9 CHAPTER 1 About EMC Virtual Storage Integrator for VMware vsphere IMPORTANT EMC recommends that you read this chapter in its entirety before installing and configuring the VSI for vsphere Client plug-in. This chapter presents the following topics: VSI for VMware vsphere overview Storage Viewer software requirements Note: Previously released versions of this product were called EMC Storage Viewer for vsphere Client. VSI for VMware vsphere version 5.6 includes all of the functionality available with previous versions of Storage Viewer. About EMC Virtual Storage Integrator for VMware vsphere 9

10 About EMC Virtual Storage Integrator for VMware vsphere VSI for VMware vsphere overview VSI is a plug-in developed by EMC for the VMware vcenter management software. VSI enables the VMware administrator to easily provision, monitor, and manage VMware vsphere datastores on EMC storage arrays. VSI supports all EMC arrays including VNX, Next-Generation VNX, XtremIO, VNXe, VMAX 10K, VMAX 20K, VMAX 40K, CLARiiON, and Celerra arrays, and VPLEX systems. It is available with VSI at no charge. Features can be added and removed from VSI independently, providing flexibility for customizing VSI user environments. You can manage features using the VSI Feature Manager. VSI provides a unified user experience, allowing you to update each of the features independently and to introduce new features rapidly in response to changing customer requirements. Features available for VSI include Storage Viewer, Path Management, Symmetrix storage replication adapter (SRA) Utilities, Unified Storage Management, AppSync Management, and EMC RecoverPoint Management. The Storage Viewer feature extends the functionality of the VMware vsphere Client to facilitate the discovery and identification of VMAX, CLARiiON, Celerra, VPLEX, VNX, VNXe, and XtremIO storage devices that are allocated to VMware ESX and ESXi hosts and virtual machines. Storage Viewer presents the underlying storage details to the virtual data center administrator by merging the data of several storage mapping tools into a few seamless vsphere Client views. Storage Viewer enables you to resolve the underlying storage of Virtual Machine File System (VMFS) and network file system (NFS) datastores and virtual disks, as well as raw device mappings (RDMs). The Path Management feature for VMware Native Multipathing and EMC PowerPath/VE enables you to change the multipath policy for groups of LUNs according to storage class and virtualization object. The Symmetrix SRA Utilities feature helps you to more efficiently manage vcenter Site Recovery Manager (SRM) configurations in Symmetrix Remote Data Facility (SRDF ) environments. It provides SRM diagnostic tools that easily identify configuration errors. The SRA Utilities feature allows you to view and create consistency groups and test failover settings. The Unified Storage Management feature provides array-based storage management and provisioning for XtremIO, CLARiiON, Celerra, VMAX, VNX, and VNXe series and VPLEX systems, and allows for virtual machine decompression, compression, cloning, and extending storage for arrays. The AppSync Management feature provides VMware vsphere datastore protection management based on EMC AppSync server with service plan configuration and datastore copy mount, unmount, restore, and expire functions. The EMC RecoverPoint Management feature assists in recovering data when you are using VMware vcenter Site Recovery Manager (SRM). With EMC RecoverPoint Management, you can select specific point-in-time backups for data protection and disaster recovery. 10 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

11 About EMC Virtual Storage Integrator for VMware vsphere Storage Viewer software requirements VMware vsphere Client Operating systems Ensure that your environment meets the requirements listed in this section. VSI requires VMware vsphere Client version 5.0 or later. Before installing VSI features, you must install the vsphere Client on the host where VSI will be installed. VSI for VMware vsphere is supported on the same operating systems supported by the VMware vsphere Client. The VMware Infrastructure Compatibility Matrixes with the complete list of supported operating systems can be found at the VMware website: Note: For x64 operating systems, all installed software components are x86 images that are running in compatibility mode. VMware vcenter server The VMware vsphere Client is used to connect to a VMware vcenter server that manages the entire virtual data center, including any number of ESX and ESXi hosts. VSI 5.6 requires VMware vcenter Server version 5.0 or later. Attempting to connect to a version of VMware vcenter Server earlier than this results in changes to the VMware vsphere Client that VSI does not support. Note: EMC VSI for VMware vsphere does not support VMware vcenter Linked Mode. VMware ESX and ESXi EMC PowerPath/VE Remote Tools Although the vsphere Client is typically used to connect to a vcenter server, connecting directly to an ESX or ESXi host is possible and sometimes necessary. In such a case, Storage Viewer version 5.6 requires VMware ESX/ESXi 5.0 or later. Attempting to connect to a version of VMware ESX or ESXi earlier than 5.0 results in changes to the vsphere Client that VSI does not support. You can operate VSI with versions of VMware ESX and ESXi earlier than 5.0 by using VMware vcenter Server version 5.0 to manage those ESX and ESXi hosts. In this case, the vsphere Client must always connect to the vcenter server and never connect directly to the ESX/ESXi host. The vcenter Server documentation provides information on the supported versions of ESX and ESXi. When PowerPath/VE is installed on an ESX or ESXi host, VSI presents important multipath details for a given device, such as the multipath policy employed, the number of active paths, the number of dead paths, and so on. Storage Viewer software requirements 11

12 About EMC Virtual Storage Integrator for VMware vsphere For VSI to obtain and present PowerPath/VE multipath details for the underlying storage, the PowerPath Remote Tools for Windows package must be installed. VSI currently supports PowerPath Remote Tools version 5.8 or later. If this software is not installed, VSI features are still installed successfully, but the PowerPath details will not be available. Note: The VSI Path Management feature is supported only when the vsphere Client is connected to a vcenter Server. If the VMware vsphere Client is connected directly to an ESX or ESXi server, the Path Management feature is disabled. EMC Solutions Enabler Installation of Solutions Enabler software is required for the Storage Viewer feature to enable the browsing capabilities of Symmetrix, CLARiiON, and VNX-Block device attributes. Solutions Enabler version for VSI is packaged with Storage Viewer version 5.6 and can be installed automatically. Chapter 2, Installation, provides more information. The steps required to configure Solutions Enabler for client/server operation can be found in Configuring Solutions Enabler for Storage Viewer on page 58. Solutions Enabler is not required for use with Celerra, VNX-File, VNXe, XtremIO, and VPLEX systems. Note: On an x64 platform, the x86 version of Solutions Enabler must be installed because both the VMware vsphere Client and the VSI are x86 applications that are running in compatibility mode. Unisphere CLI Navisphere CLI Symmetrix arrays To manage EMC VNXe storage systems, EMC Unisphere CLI version 1.5 or later must be installed on the vsphere Client host. To manage CLARiiON and VNX systems, EMC Navisphere Secure CLI version 7.32 or later must be installed on the vsphere Client host. VSI for VMware vsphere currently supports all Symmetrix storage arrays that are supported with the versions of Solutions Enabler and VMware ESX/ESXi that you are using. For detailed interoperability information, refer to the EMC E-Lab Interoperability Navigator. For VSI to resolve Symmetrix LUNs properly, all of the front-end ports that are used in the VMware environment must have the SPC-2 flag enabled. Without the SPC-2 flag enabled, the unique World Wide Name (WWN) of each LUN is not reported properly, and the plug-in is not able to identify the LUN in the virtual environment. To confirm that your current level of EMC Enginuity supports the SPC-2 flag, review the Knowledgebase article emc on EMC Online Support. Security considerations on page 60 provides more information. 12 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

13 About EMC Virtual Storage Integrator for VMware vsphere CLARiiON arrays VSI for VMware vsphere Client currently supports CLARiiON storage arrays that are running EMC FLARE release 19 or later. Celerra arrays VSI for VMware vsphere currently supports any Celerra arrays that are running network-attached storage (NAS) release or later. The Storage Viewer feature only supports Celerra NFS storage. Ensure that the Celerra NFS license is enabled on the Control Station: From the Celerra Manager, click Licenses in the Celerra home page and select NFS License. The Celerra documentation provides instructions on enabling licenses. Note: The Storage Viewer feature does not support Celerra iscsi storage. Celerra iscsi LUNs appear as Unknown in Storage Viewer. Solutions Enabler is not used to manage Celerra systems. Instead, a client-side library is used to communicate with the Celerra system over TCP/IP, and a list of available Celerra systems are maintained locally in a private, encrypted file. The username, password, and Celerra system details are stored in this encrypted file and retrieved at runtime. VNX series arrays VSI for VMware vsphere version 5.6 supports VNX series storage arrays that are running VNX Operating Environment (OE) for Block software version 5.31 or later and VNX OE for File software version 7.0 or later. Note: Solutions Enabler is used to manage VNX-Block, while a separate client-side library is used to manage VNX-File. VNXe series arrays VSI for VMware vsphere version 5.6 supports VNXe series storage arrays that meet the following requirements: VNXe OE software version or later is installed. NFS license is enabled (to view file-based storage). iscsi license is enabled (to view block storage). Each ESX host that will access the iscsi storage is connected to the iscsi target on the array. Unisphere CLI version 1.5 or later is installed on the VMware vsphere Client host. Storage Viewer software requirements 13

14 About EMC Virtual Storage Integrator for VMware vsphere VPLEX systems VSI for VMware vsphere version 5.6 supports any VPLEX system running EMC GeoSynchrony version 4.0 to 5.2. Local, and Metro, configurations are supported. Note: Solutions Enabler is not used to manage VPLEX systems. Instead, a client-side library is used to communicate with the VPLEX systems over TCP/IP, and a list of available VPLEX systems are maintained locally in a private, encrypted file. The username, password, and VPLEX system details are stored in this encrypted file and retrieved at runtime. XtremIO storage systems VSI for VMware vsphere version 5.6 supports XtremIO 2.2. Note: Solutions Enabler does not manage XtremIO systems. Instead, a client-side library communicates with the XtremIO systems over TCP/IP, and a list of available XtremIO systems is maintained locally in a private, encrypted file. The username, password, and XtremIO system details are stored in this encrypted file and retrieved at runtime. 14 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

15 CHAPTER 2 Installation This chapter presents the following topics: Installation overview Installing VSI features Enabling VSI Disabling VSI Uninstalling VSI Installation 15

16 Installation Installation overview Ensure that the requirements in Storage Viewer software requirements on page 11 have been met before installing VSI Storage Viewer. Features are installed separately and contain the complete VSI plug-in framework for using the feature. Storage Viewer and EMC Solutions Enabler Solutions Enabler provides the libraries necessary for VSI Storage Viewer to properly discover and map the Symmetrix, CLARiiON, and VNX block storage arrays. If you are performing a custom installation of Solutions Enabler, the only required components are the Core and Base Storage components. The storage does not have to be directly connected to the host where VSI is installed. Instead, it is possible to use a Solutions Enabler server (such as the Solutions Enabler Virtual Appliance) elsewhere in the data center as the source for storage array information. Even in that case, Solutions Enabler must be installed on the VSI host to make the client libraries available. The steps required to configure Solutions Enabler for client/server operation can be found in Configuring Solutions Enabler for Storage Viewer on page 58. Note: Using VSI Storage Viewer does not require any Solutions Enabler licenses. Installing VSI features Upgrading After you have installed the VMware vsphere Client, you can install VSI for VMware vsphere features: 1. Download the VSI for VMware vsphere feature Zip file from EMC Online Support. 2. Unzip the file and run the emc-vsi-sv vmware-vsphere-windows-x86.exe file. The installation wizard copies all of the necessary files. Each feature is installed separately and contains all of the necessary components for that feature. No configuration or input is required during the installation other than accepting the prompts to move forward with the installation. The installation directory cannot be changed because the VMware vsphere Client requires the plug-in files to be saved in a specific location. If VSI version 3.x or later is installed, you can upgrade the software to a newer version using the installation wizard. The upgrade to version 5.6 does not retain any of the configuration options, but the log files are retained for Storage Viewer and the Solutions Enabler server. IMPORTANT After you upgrade VSI, certain features may be removed and must be reinstalled. 16 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

19 CHAPTER 3 Using VSI This chapter presents the following topics: Getting started with VSI Using Storage Viewer Viewing ESX or ESXi storage Viewing virtual machine storage Viewing datastore storage Performance monitoring Using VSI 19

20 Getting started with VSI You can use VSI to connect to either a vcenter Server or directly to an ESX/ESXi host. To open the VSI plug-in, open the VMware vsphere Client and navigate to Home > Solutions and Applications > EMC VSI. Figure 1 shows the VSI window. The main window displays information related to the selection in the Settings or Features pane. These panes provide the following functionality: Settings Provides access to the Feature Manager function, which is used to manage the plug-in features. It also provides access to logging information for each installed feature. VSI logging on page 61 provides information for using the VSI logging function. Features This pane displays information related to the VSI features that are installed. With Storage Viewer installed, this pane lists all of the storage arrays and servers that VSI has discovered and allows for the discovery of new arrays and the deletion of previously discovered arrays. Figure 1 VSI plug-in features To view the installed VSI features, under Settings, select Feature Manager. All installed VSI features are displayed in a list. Figure 1 shows an example with multiple features installed and enabled. 20 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

21 Using the vsphere Client and VSI The EMC VSI tab in the vsphere Client provides context-sensitive storage information depending on the object that is selected from the inventory navigation tree located in the left pane. Figure 2 shows an ESX/ESXi host selected from the inventory list. The related information for the host is displayed in the EMC VSI window. Using Storage Viewer Viewing storage array information Figure 2 Opening an ESX or ESXi host view The Storage Viewer feature facilitates the discovery and identification of supported storage devices that are allocated to VMware ESX/ESXi hosts and virtual machines. With Storage Viewer you can resolve the underlying storage of VMFS and NFS datastores and virtual disks, as well as RDM. You can view lists of storage arrays and devices that are accessible to the ESX and ESXi hosts in the virtual data center. Storage Viewer provides storage mapping and connectivity details for supported devices. From the vsphere Client, navigate to Home > Solutions and Applications > EMC. From the Features pane in the EMC VSI window, you can view all of the storage systems that VSI recognizes. You can use the Solutions Enabler to manage Symmetrix, CLARiiON, and VNX-Block storage arrays. Celerra, VPLEX, VNXe, and VNX file systems are managed independently. Using Storage Viewer 21

22 As shown in Figure 3, the EMC VSI window allows you to discover new arrays, synchronize the Solutions Enabler data for a given array, and remove arrays. The list displays the properties related to each array. Note: Symmetrix arrays cannot be removed by using VSI. Figure 3 Viewing Symmetrix arrays The following information is displayed for supported storage systems: Auto Sync This column is displayed for Symmetrix storage arrays, CLARiiON storage arrays, and VNX systems and indicates whether the array or system is automatically synchronized by VSI. When selected, VSI automatically synchronizes with the array or system to update details, such as storage group, friendly names, and so on. When cleared, VSI does not automatically synchronize with the array or system. You can manually synchronize with the array by clicking Sync Array or Sync All Arrays for CLARiiON and Symmetrix arrays, or Sync System or Sync All Systems for VNX systems. Selecting Auto Sync makes VSI more responsive to changes, but it can have a negative effect on performance. For this reason, you should carefully evaluate which arrays and systems to auto-synchronize. Note: Check All toggles to Uncheck All depending on Auto Sync selections. Name Displays the serial number or friendly name, if configured, of the array or system. Name - IP Address Displays the hostname or IP address that was used to discover the VPLEX system. Management IP Displays the IP address that was used to discover the CLARiiON array or VNX/VNXe system. 22 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

23 Model Displays the model of the array or system, such as VMAX-1, DMX3-6, CX4-480, NS500, and VNX5500. For VPLEX systems, displays Local, Metro, or Geo as possible values. Block OE Displays the VNX OE for Block software version. File OE Displays the VNX OE for File software version. ID Displays the serial number of the Symmetrix, Celerra array, VNXe, or VPLEX system. Firmware Displays the level of firmware that is running on the array. For Symmetrix arrays, this is the level of Enginuity. For CLARiiON arrays, this is the level of FLARE. For Celerra, this is the level of NAS software (DART). For VPLEX, this is the version of GeoSynchrony. Note: As a known issue with VPLEX, this column shows 4.1 when version 4.0 of GeoSynchrony is installed. Attachment Displays whether the Symmetrix or CLARiiON storage array is local or remote to Solutions Enabler. CLARiiON arrays are always displayed as local. Symmetrix arrays also are displayed as local, with the exception of those that have been discovered over an SRDF connection, which are displayed as remote. LUNs Displays the total number of LUNs configured on the Symmetrix or CLARiiON array or VNX or VNXe system. For CLARiiON arrays, this also includes snapshot LUNs. Disks Displays the total number of physical disks that are contained within the Symmetrix or CLARiiON array or VNX system. Front-End Ports Displays the total number of ports on the Symmetrix or CLARiiON array or VNX system to which a host can connect. Data Movers Displays the number of data movers in the Celerra array or VNX system. File Systems Displays the number of file systems configured on the Celerra array or VNX system. Distributed Volumes Displays the number of distributed virtual volumes configured on the VPLEX system. Local Volumes Displays the number of local virtual volumes configured on the VPLEX system. Shared Folders Displays the number of shared folders in the VNXe system. Note: If an array is missing from the list, LUNs from that array are displayed as Unknown throughout the other VSI views. Using Storage Viewer 23

24 Discovering storage arrays The storage array information views provide a means for discovering new storage arrays and systems as described in the following sections for supported storage systems. Symmetrix arrays CLARiiON arrays The Symmetrix storage array view provides the ability to perform an in-band discovery of Symmetrix arrays. Discovering an array in-band indicates that Solutions Enabler has direct access to the array through a LUN (such as a gatekeeper device), with all discovery being performed over a fibre connection. Clicking Discover New Symmetrix discovers all Symmetrix arrays that have a LUN accessible to the Solutions Enabler server. Each new Symmetrix array discovered is displayed in the Symmetrix arrays list. User credentials are not required to perform this discover operation. The CLARiiON storage array view provides the ability to perform an assisted discovery of CLARiiON arrays. Assisted discovery indicates that you have directed Solutions Enabler to a particular storage array, with all discovery being performed over the TCP/IP network. The view allows you to input the IP address of the CLARiiON storage processors, as well as the username and password for gaining access to the CLARiiON array. After populating these fields, you can click Discover New CLARiiON Array to discover the new CLARiiON array. Each CLARiiON array discovered appears in the CLARiiON arrays list. Each CLARiiON array must be discovered separately. As part of the assisted discovery, VSI adds the user credentials to Solutions Enabler for the purpose of discovering the CLARiiON array. If Solutions Enabler already contains user credentials for these storage processors, these credentials are overwritten with the ones entered. Users with the role of Administrator or Manager can discover a CLARiiON array. The Celerra storage array view provides the ability to perform an assisted discovery of Celerra arrays without involving Solutions Enabler. Instead, a client-side library is used to discover the array and to persist the user credentials. The view allows you to input the network name or IP address of the Celerra Control Station, as well as the username and password for gaining access to the Celerra array. After populating these fields, clicking Discover New Celerra System discovers the new Celerra array. Each Celerra array discovered appears in the list. Each Celerra array must be discovered separately. As part of the assisted discovery, the Celerra user credentials are encrypted and stored locally to be used for seamless access. Future assisted discover operations for the same Celerra array will overwrite these user credentials; therefore, if the credentials need to change, repeat this assisted discovery operation. It is not necessary to remove the array first. VPLEX systems The VPLEX systems view provides the ability to discover a new VPLEX system, without involving Solutions Enabler. The view allows you to input the hostname or IP address of the VPLEX Management Station, as well as the username and password for gaining access to the system. After populating these fields, click Discover New VPLEX System to discover the new VPLEX system. Each VPLEX system discovered appears in the list. Each VPLEX system must be discovered separately. 24 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

25 As part of the assisted discovery, the VPLEX user credentials are encrypted and stored locally to be used for seamless access. Future assisted discovery operations for the same VPLEX system will overwrite these user credentials; therefore, if the credentials need to change, repeat this assisted discovery operation. It is not necessary to remove the system first. XtremIO systems The XtremIO system view provides the ability to discover a new XtremIO system. The view allows you to input the XtremIO Management host name or IP address, as well as the host username, host password, command line console username, and command line console password. After populating these fields, click Discover New XtremIO System to discover the new XtremIO system. Each XtremIO system must be discovered separately, and then appears in the list. VNX systems The VNX systems list includes support for VNX-File and VNX-Block. Although the two are discovered separately, with potentially different credentials, they are displayed as a single storage system. Since it is possible to have a file-only VNX or block-only VNX system, it is normal for half of the fields to display NA. For example, if you discover a file-only VNX, the Block OE column is displayed as NA. It is also possible to discover only the file portion or block portion of a VNX system that has both. In that case, it is all right to discover the other half later, or even both of the systems at a later time, to update the existing VNX system with all of the details that were previously NA. The Scope list for both VNX-Block and VNX-File allows you to choose either Global, Local, or LDAP credentials for the discovery. Global is the default for both VNX-Block and VNX-File. When discovering a VNX-Block using LDAP, you are not required to enter a domain name, as this is already configured on the system. However, when discovering a VNX-File system using LDAP, you are required to enter a domain name. The Domain box is disabled until LDAP is selected for the scope. When LDAP is selected, the box is colored red to alert you that a value is required. Note: LDAP discovery of a VNX-Block requires Solutions Enabler version or later on both the client and server. In some cases, the same credentials can be used to discover both the VNX-Block and VNX-File. In that case, you can select Use same credentials from bloc and the VNX-File credentials mirror those entered for VNX-Block. Clearing the checkbox resets the VNX-File credentials back to their default values. Certain user-defined roles can be used to discover a VNX system. VNX-Block discovery is successful for users with the following roles: Administrator Storage administrator SAN administrator Using Storage Viewer 25

26 To discover VNX-Block arrays, use Solutions Enabler. To discover VNX-File, use independent APIs. This means that if you use a Solutions Enabler server, the VNX-Block systems travel from client to client (as long as the client uses that same Solutions Enabler server). However, the VNX-File systems do not travel from client to client and are required to be discovered separately on each client. Figure 4 shows the VNX system information that is displayed in VSI. Figure 4 VNX system information VNXe systems In order to discover new VNXe systems, you must provide the management IP address or host name, as well as the username and password with permission to access the storage system. The Scope list for VNXe allows you to choose either Local (default) or LDAP credentials to be used for the discovery. When discovering a VNXe system using LDAP, you must enter a domain name into the Domain box. This box is disabled until LDAP is selected for the scope. Synchronizing array data The Symmetrix and CLARiiON views provide the following two ways of synchronizing the Solutions Enabler data for discovered arrays: Sync All Arrays Click Sync All Arrays to update Solutions Enabler with new data for all of the arrays shown in the Arrays view. Sync Array After selecting a storage array, click Sync Array to update Solutions Enabler with data for the selected array. Synchronizing the Solutions Enabler data with the arrays is important when configuration changes have occurred on the array, such as creating a new LUN, converting an existing LUN to a meta or composite, changing a LUN's RAID type, or reconfiguring front-end port settings. If VSI is not synchronized with the array, these changes might not be displayed. Similarly, for VNX systems, click Sync System or Sync All Systems to update system data. 26 EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

27 Removing arrays The performance of VSI can be negatively affected by the number of arrays in the lists, since VSI often needs to iterate through each of the arrays. For this reason, it is good practice to keep the list as short as possible. If a CLARiiON, Celerra, VPLEX, VNX, or VNXe storage system is no longer being used, you can click Remove Array/System to remove the array or system from the list. Removing the system does not remove the associated user privileges. Note: Symmetrix arrays cannot be removed by using VSI. Refreshing the array lists To force VSI to refresh the list of arrays and their properties, click Refresh List. Refresh List does not cause a synchronization of data with the array. It simply gathers a new list of arrays for the given type and displays them in their respective lists. Status pane The Status pane communicates progress, failures, and success for all of the storage view operations described above. Many of the array operations, such as discovery and synchronization, are long running tasks, so animated icons are used to show that the operation is progressing. When a failure occurs, important error messages are posted in the Status pane. Successful operations are also noted in the Status pane. Viewing ESX or ESXi storage To access the ESX/ESXi host view, select an ESX/ESXi host, and then select EMC VSI. The Features pane provides access to details for Datastores, LUNs, and Targets. Figure 5 shows the EMC VSI window with Datastores selected. Figure 5 ESX/ESXi host view Note: The LUNs view presents the option to show or hide the Storage Details pane. Viewing ESX or ESXi storage 27

44 Viewing virtual disks The Virtual Disks view provides an easy way to map virtual disks to their respective EMC storage devices. As shown in Figure 15 on page 44, the data is presented Virtual Disks and Storage Details views. The Virtual Disks pane lists the virtual disks for the selected virtual machine. To refresh the information in this pane, click Refresh. To map virtual disks to the underlying storage devices, follow these steps: 1. In the Features pane, select Virtual Disks. 2. Select a virtual disk in the Virtual Disks list. The storage detail information for the selected virtual disk is displayed in the Storage Details pane. Figure 15 Virtual Machine level Virtual Disks subview The Virtual Disks pane includes the following fields: Name Shows the name of the selected virtual disk. ID Shows the ID of the selected virtual disk. Size Shows the size of the selected virtual disk. Datastore Shows the name of the datastore for the virtual disk. Filename Shows the name and the full path to the virtual disk file, including the datastore name in brackets. Mode Shows the mode of the virtual disk, such as persistent, non-persistent, independent persistent, or independent non-persistent. Type Shows the type of provisioning for the virtual disk, such as Thin, Thick, or Eager Thick. Note: For a Celerra or VNX NFS virtual disk, the Storage Details pane displays a different set of criteria as described in NFS virtual disks on page EMC VSI for VMware vsphere: Storage Viewer Version 5.6 Product Guide

45 Note: For a VPLEX virtual disk, the Storage Details pane displays a different set of criteria as described in VPLEX virtual disks on page 49. VMFS virtual disks Common view The Storage Details pane provides these views: Common, Storage Pools, and Paths. Click a button to change the view in the Storage Details pane. Total LUNs shows the total number of LUNs that comprise the datastore. This field is empty when no virtual disk is selected and displays 1 when a virtual disk is selected that does not reside on EMC storage. The Common view lists the storage devices that comprise the underlying storage for the datastore that contains the selected virtual disk. Note: Right-click the column headers to view a list of available column headers that can be displayed or hidden. The Common view lists the following column information: Runtime Name Shows the runtime name of the device hosting the datastore. This value can be used when trying to cross-reference LUNs from this pane and other VMware panes, such as when creating a new datastore. Product Shows the product type of underlying storage, such as Symmetrix or CLARiiON. Model Shows the model type of the underlying storage, such as DMX-3, VMAX-1 SE, or CX4_240. Revision Shows the revision level returned by the device in response to the SCSI inquiry data command. For Symmetrix LUNs, it is the Enginuity level. For CLARiiON LUNs, it is the FLARE level. Array Shows the serial number of the array on which the LUN resides. If a friendly name is configured for the array, it appears in place of the serial number. Device Name Shows either the Symmetrix device number or the CLARiiON device number for the LUN. If a friendly name is configured for the device, it appears in place of the device number. Virtual Volume Name Shows the name of the virtual volume within the VPLEX system. Device ID Shows either the Symmetrix device number or the CLARiiON device number for the LUN. Type Shows any special attributes of the device such as BCV, VDEV, R1, and so on. RAID Shows the RAID protection type for the LUN. Capacity Shows the total capacity of the LUN. Locality Identifies where the virtual volume resides in the VPLEX system, relative to the local and remote clusters. Possible values are: Distributed, Local, and Remote. Viewing virtual machine storage 45

46 Visibility Identifies where the virtual volume can be viewed within the VPLEX system, relative to the local and remote clusters. Possible values are: Global, Local, and Remote. Storage Group Shows the name of the storage group to which the LUN is assigned. Rule Set Identifies the name of the rule set that is currently active for the virtual volume. The rule set determines the actions of the VPLEX system if a split-brain scenario is encountered for this virtual volume. This field is only applicable for distributed virtual volumes. META Indicates whether the LUN is a metavolume. If it is, then this field indicates the type, such as concatenated or striped. This column is not shown by default, right-click on the column headers to add. Pool Indicates the name of the Storage Pool that the LUN belongs to. FAST VP Policy Indicates the name of the FAST VP policy if the LUN is associated with one. Paths Shows the number of paths from the ESX/ESXi host to the LUN. At least one path should be available at any given time, so this value should always be greater than zero. When PowerPath/VE is installed on the ESX/ESXi host, the active paths are shown in relation to the total paths, such as 4/4 or 2/4. Owner Shows the multipath entity that owns this particular LUN. For example, NMP is VMware's Native Multipathing Plug-in, and is shown as the default owner. When PowerPath/VE is installed on the ESX/ESXi host, the owner appears as PowerPath. Policy Shows the multipath policy that is currently set for the LUN. Some possible policy values for PowerPath owned LUNs are CLAROpt, SymmOpt, and RoundRobin. Used by Indicates whether a LUN is used by a datastore or as an RDM to a virtual machine. For RDM, displays the name of the datastore or virtual machine that is using the LUN as an RDM. Storage Type Shows the name (label) of the Storage Type for the associated LUN. Storage Pools view Paths view Storage Pools view on page 31 provides details. The Paths view contains multipath information for PowerPath and NMP, depending on which type of multipathing is used. Paths view on page 32 provides more information.
