11 1 Introduction This chapter provides an overview of the Hitachi RAID storage systems and host attachment: About the Hitachi RAID Storage Systems Device Types Host Attachment Roadmap Introduction 1-1

12 About the Hitachi RAID Storage Systems The Hitachi RAID storage systems offer a wide range of storage and data services, including thin provisioning with Hitachi Dynamic Provisioning software, application-centric storage management and logical partitioning, and simplified and unified data replication across heterogeneous storage systems. These storage systems are an integral part of the Services Oriented Storage Solutions architecture from Hitachi Data Systems, providing the foundation for matching application requirements to different classes of storage and delivering critical services such as: Business continuity services Content management services (search, indexing) Non-disruptive data migration Volume management across heterogeneous storage arrays Thin provisioning Security services (immutability, logging, auditing, data shredding) Data de-duplication I/O load balancing Data classification File management services The Hitachi RAID storage systems provide heterogeneous connectivity to support multiple concurrent attachment to a variety of host operating systems, including Windows as well as VMware, UNIX, Linux, and mainframe servers, enabling massive consolidation and storage aggregation across disparate platforms. The storage systems can operate with multi-host applications and host clusters, and are designed to handle very large databases as well as data warehousing and data mining applications that store and retrieve terabytes of data. The Hitachi RAID storage systems are configured with OPEN-V logical units (LUs) and are compatible with most fibre-channel (FC) host bus adapters (HBAs) and FC-over-ethernet (FCoE) converged network adapters (CNAs). Users can perform additional LU configuration activities using the LUN Manager, Virtual LVI/LUN (VLL), and LUN Expansion (LUSE) features provided by the Storage Navigator software, which is the primary user interface for the storage systems. For further information about storage solutions and the Hitachi RAID storage systems, please contact your Hitachi Data Systems account team. 1-2 Introduction

13 Device Types Table 1-1 describes the types of logical devices (volumes) that can be installed and configured for operation with the Hitachi RAID storage system on a Microsoft Windows operating system. Table 1-2 lists the specifications for devices supported by the Hitachi RAID storage system. Logical devices are defined to the host as SCSI disk devices, even though the interface is fibre channel. For information about configuring devices other than OPEN-V, contact your Hitachi Data Systems representative. The sector size for the devices is 512 bytes. Table 1-1 Device Type OPEN-V Devices OPEN-x Devices LUSE Devices (OPEN-x*n) VLL Devices (OPEN-x VLL) VLL LUSE Devices (OPEN-x*n VLL) FX Devices (3390-3A/B/C, OPEN-x-FXoto) Logical Devices Supported by the Hitachi RAID storage systems Description OPEN-V logical units (LUs) are disk devices (VLL-based volumes) that do not have a predefined size. The OPEN-x logical units (LUs) (for example, OPEN-3, OPEN-9) are disk devices of predefined sizes. Hitachi RAID storage system supports OPEN-3, OPEN-8, OPEN-9, OPEN-E, and OPEN-L devices. For information about usage of these device types, please contact your Hitachi Data Systems account team. LUSE devices are combined LUs that can be from 2 to 36 times larger than standard OPEN-x LUs. Using LUN Expansion (LUSE) remote console software, you can configure these custom-size devices. LUSE devices are designated as OPEN-x*n, where x is the LU type (for example, OPEN-9*n) and 2< n < 36). For example, a LUSE device created from 10 OPEN-3 LUs is designated as an OPEN-3*10 disk device. This lets the host combine logical devices and access the data stored on the Hitachi RAID storage system using fewer LU numbers. VLL devices are custom-size LUs that are smaller than standard OPEN-x LUs. Using Virtual LVI/LUN remote console software, you can configure VLL devices by slicing a single LU into several smaller LUs that best fit your application needs to improve host access to frequently used files. The product name for the OPEN-x VLL devices is OPEN-x-CVS (CVS stands for custom volume size). The OPEN-L LU type does not support Virtual LVI/LUN. VLL LUSE devices combine Virtual LVI/LUN devices (instead of standard OPEN-x LUs) into LUSE devices. Use the Virtual LVI/LUN feature to create custom-size devices, then use the LUSE feature to combine the VLL devices. You can combine from 2 to 36 VLL devices into one VLL LUSE device. For example, an OPEN-3 LUSE volume created from a0 OPEN-3 VLL volumes is designated as an OPEN-3*10 VLL device (product name OPEN-3*10-CVS). The Hitachi Cross-OS File Exchange (FX) feature allows you to share data across mainframe, UNIX, and PC server platforms using special multiplatform volumes. The VLL feature can be applied to FX devices for maximum flexibility in volume size. FX devices are not SCSI disk devices, and must be installed and accessed as raw devices. Windows hosts must use FX to access the FX devices as raw devices (no file system, no mount operation). The B devices are write-protected from Windows host access. The Hitachi RAID storage system rejects all Windows host write operations (including fibre-channel adapters) for B devices. The A/C and OPEN-x-FXoto devices are not write-protected for Windows host access. Do not execute any write operations on these devices. Do not create a partition or file system on these devices. This will overwrite data on the FX device and prevent the FX software from accessing the device. For more information about FX, see the Hitachi Cross-OS File Exchange User s Guide, or contact your Hitachi Data Systems account team. Introduction 1-3

15 Notes 1. The availability of specific device types depends on the storage system model and the level of microcode installed on the storage system. 2. The category of a device (SCSI disk or FX) determines its volume usage. Table 1-3 below shows the volume usage for SCSI disk and FX devices. The SCSI disk devices (OPEN-V, VLL, LUSE, and VLL LUSE) are usually formatted with file systems for Windows operations. The FX devices (3390-3A/B/C, and OPEN-x-FXoto) must be installed as raw devices and can only be accessed using the FX software. Do not partition or create a file system on any device used for FX operations. Do not write a signature on an FX device unless used in an MSCS environment. 3. The command device (used for Command Control Interface (CCI) operations) is distinguished by CM on the product name (for example, OPEN-3-CM, OPEN-3-CVS-CM). The product name for VLL devices is OPEN-x-CVS, where CVS = custom volume size. 4. This capacity is the maximum size which can be entered using the lvcreate command. The device capacity can sometimes be changed by the BIOS or host bus adapter. Also, different capacities may be due to variations such as 1 MB = or bytes. 5. The number of blocks for a VLL volume is calculated as follows: # of blocks = (# of data cylinders) (# of heads) (# of sectors per track) The number of sectors per track is 128 for OPEN-V and 96 for the other emulation types. Example: For an OPEN-3 VLL volume with capacity = 37 MB: # of blocks = (53 cylinders see Note 3) (15 heads) (96 sectors per track) = The number of data cylinders for a Virtual LVI/LUN volume is calculated as follows ( means that the value should be rounded up to the next integer): Number of data cylinders for OPEN-x VLL volume (except for OPEN-V) = # of cylinders = (capacity (MB) 1024/720 Example: For OPEN-3 VLL volume with capacity = 37 MB: # of cylinders = /720 = = 53 cylinders Number of data cylinders for an OPEN-V VLL volume = # of cylinders = (capacity (MB) specified by user) 16/15 Example: For OPEN-V VLL volume with capacity = 50 MB: # of cylinders = 50 16/15 = = 54 cylinders Number of data cylinders for a VLL LUSE volume (except for OPEN-V) = # of cylinders = (capacity (MB) 1024/720 n Example: For OPEN-3 VLL LUSE volume with capacity = 37 MB and n = 4: # of cylinders = /720 4 = = 53 4 = 212 Number of data cylinders for an OPEN-V VLL LUSE volume = # of cylinders = (capacity (MB) specified by user) 16/15 n Example: For OPEN-V VLL LUSE volume with capacity = 50 MB and n = 4: # of cylinders = 50 16/15 4 = = 54 4 = 216 Number of data cylinders for a A/C = # of cylinders = (number of cylinders) + 9 Number of data cylinders for a B VLL volume = # of cylinders = (number of cylinders) The size of an OPEN-x VLL volume is specified by capacity in MB, not number of cylinders. The size of an OPEN-V VLL volume can be specified by capacity in MB or number of cylinders. The user specifies the volume size using the Virtual LVI/LUN software. Introduction 1-5

19 2 Installing the Storage System This chapter describes how to install the Hitachi RAID storage system on a Microsoft Windows operating system: Requirements Preparing for Host Attachment Connecting to the Windows Host Configuring the Verifying the Disk and Device Parameters Installing the Storage System 2-1

20 Requirements Table 2-1 lists and describes the requirements for installing the Hitachi RAID storage system on the Windows operating system. Table 2-1 Requirements Requirements Hitachi RAID storage system Windows server or workstation Windows operating system Fibre-channel HBAs Fibre-channel over ethernet CNAs Setup utilities and tools for host adapters FC and FCoE drivers Description The availability of features and devices depends on the level of microcode installed on the Hitachi RAID storage system. The LUN Manager software on Storage Navigator is used to configure the fibre-channel ports. Refer to the Microsoft user documentation for PC server hardware requirements. Please refer to the Hitachi Data Systems interoperability matrix for specific support information for the Windows operating system: The Hitachi RAID storage system supports fibre-channel HBAs equipped as follows: 8-Gbps fibre-channel interface, including shortwave non-ofc (open fibre control) optical interface and multimode optical cables with LC connectors. 4 Gbps FC interface, including shortwave non-ofc optical interface and multimode optical cables with LC connectors. 2 Gbps FC interface, including shortwave non-ofc optical interface and multimode optical cables with LC connectors. 1 Gbps FC interface, including shortwave non-ofc optical interface and multimode optical cables with SC connectors. If a switch or HBA with a 1 Gbps transfer rate is used, configure the device to use a fixed 1 Gbps setting instead of Auto Negotiation. Otherwise, it may prevent a connection from being established. However, the transfer speed of CHF port cannot be set as 1 Gbps when the CHF is 8US/8UFC/16UFC. Therefore 1 Gbps HBA and switch cannot be connected. Do not connect OFC-type fibre-channel interfaces to the Hitachi RAID storage system. For information about supported fibre-channel adapters, cables, hubs, and switches, refer to the Hitachi Data Systems interoperability matrix: The Hitachi Virtual Storage Platform supports FCoE CNAs equipped as follows: 10 Gbps fibre-channel over Ethernet interface, including shortwave non- OFC (open fibre control) optical interface and multimode optical cables with LC connectors. For information about supported CNAs, cables, hubs, and switches, refer to the Hitachi Data Systems interoperability matrix: Refer to the documentation for your host adapter for information about installing and using the setup utilities and tools. Do not install/load the drivers yet. When instructed in this guide to install the drives for your host adapter, refer to the documentation for your adapter. 2-2 Installing the Storage System

21 Preparing for Host Attachment This section describes the tasks that must be performed before attaching the Hitachi RAID storage system to the host: Installing the Hitachi RAID Storage System Hardware Setting the System Option Modes Installing the LUN Manager Software Setting the Host Mode Options Configuring the Fibre-Channel Ports Installing the Hitachi RAID Storage System Hardware The Hitachi Data Systems representative performs the hardware installation by following the precautions and procedures in the Maintenance Manual for the storage system. Hardware installation activities include: Assembling all hardware and cabling. Installing and formatting the logical devices (LDEVs). Be sure to obtain the desired LDEV configuration information from the user, including the desired number of OPEN-x, LUSE, VLL, VLL LUSE, and multiplatform (FX) devices. Installing fibre-channel HBAs/FCoE CNAs and cabling. The total fibre cable length attached to each HBA must not exceed 500 meters (1,640 feet). Do not connect any OFC-type connectors to the Hitachi RAID storage system. Do not connect/disconnect fibre-channel cabling that is being actively used for I/O. This can cause the Windows system to hang. Always confirm that the devices on the fibre cable are offline before connecting/disconnecting the fibre cable. Configuring the fibre port topology. The fibre topology parameters for each fibre-channel port on the storage system depend on the type of device to which the port is connected, and the type of port. Determine the topology parameters supported by the device, and set your topology accordingly (see Configuring the USP V/VM Fibre-Channel Ports). Before starting the installation, check all specifications to ensure proper installation and configuration. Installing the Storage System 2-3

22 Setting the System Option Modes To provide greater flexibility and enable the Hitachi RAID storage system to be tailored to unique customer operating requirements, additional operational parameters called system option modes are available. At installation, the system option modes are set to their default values. The system option modes are set on the service processor (SVP) and can only be changed by the Hitachi Data Systems representative. To ensure that the appropriate system option modes are set: 1. Review the system option modes for your storage system model. The system option modes are listed and described in the User and Reference Guide for your storage system model: HUS VM User and Reference Guide, MK-92HM7005 Hitachi VSP User and Reference Guide, MK-90RD7042 Hitachi USP V/VM User and Reference Guide, MK-96RD Discuss the system option modes with your Hitachi Data Systems representative, and ask the representative to set the system option modes that apply to your configuration and environment. Installing the LUN Manager Software The LUN Manager software on Storage Navigator is used to configure the fibre-channel ports on the Hitachi RAID storage system. The user or Hitachi Data Systems representative installs the LUN Manager software. For instructions on installing LUN Manager, see the Storage Navigator User Guide for the storage system. For instructions on using LUN Manager, see the Provisioning Guide or the LUN Manager User s Guide for the storage system. 2-4 Installing the Storage System

23 Setting the Host Modes You can connect multiple server hosts of different platforms to a single port, but you must group server hosts connected to the storage system by host groups, which are segregated by platform. For example, if both Windows and VMware hosts are connected to a single port, you must first create a separate host group for each platform, and then register the hosts to the corresponding host group. When you create a host group, you need to set the host mode and host mode options for the group. Use Storage Navigator to create host groups, register hosts in host groups, and set host modes and host mode options. For instructions see the Provisioning Guide or the LUN Manager User s Guide. The required host mode for Windows is 0C Windows or 2C Windows Extension. Do not select a host mode other than 0C or 2C for Windows. Either setting is required to support MSCS failover and to recognize more than eight LUs. If you plan to create LUSE volumes, use host mode 2C Windows Extension. If you plan to create a LUSE volume using a volume to which an LU path has already been defined, you must use host mode 2C Windows Extension. WARNING: Changing host modes on a Hitachi RAID storage system that is already installed and configured is disruptive and requires the server to be rebooted. Installing the Storage System 2-5

24 Setting the Host Mode Options When each new host group is added, the storage administrator must make sure that the host mode options (HMOs) are set for all host groups connected to Windows hosts. Table 2-2 lists and describes the HMOs that can be used for Windows operations. Use the LUN Manager software on Storage Navigator to set the HMOs. WARNING: Before setting any HMO, review its functionality carefully to determine whether it can be used for your configuration and environment. If you have any questions or concerns, contact your Hitachi Data Systems representative or the Support Center. Changing HMOs on a Hitachi RAID storage system that is already installed and configured is disruptive and requires the server to be rebooted. Table 2-2 Host Mode Options for Windows Operations HMO Storage System Function Host mode Comments 2 HUS VM Veritas DBE+RAC Common Mandatory. VSP USP V/VM (1) The response of Test Unit Ready(TUR) for Persistent Reserve is changed.

27 HMO Storage System Function Host mode Comments 48 USP V/VM By setting this option to ON, in normal operation, the pair status of S-VOL is not changed to SSWS even when Read commands exceeding the threshold (1,000/6 min) are issued while a specific application is used. ON: The pair status of S-VOL is not changed to SSWS if Read commands exceeding the threshold are issued. OFF (default): The pair status of S-VOL is changed to SSWS if Read commands exceeding the threshold are issued. Note: 1. Set this option to ON for the host group if the transition of the pair status to SSWS is not desired in the case that an application that issues Read commands (*1) exceeding the threshold (1,000/6 min) to S-VOL is used in HAM environment. *1: Currently, the vxdisksetup command of Solaris VxVM serves. 2. Even when a failure occurs in P-VOL, if this option is set to ON, which means that the pair status of S-VOL is not changed to SSWS (*2), the response time of Read command to the S-VOL whose pair status remains as Pair takes several msecs. On the other hand, if the option is set to OFF, the response time of Read command to the S-VOL is recovered to be equal to that to P-VOL by judging that an error occurs in the P-VOL when Read commands exceeding the threshold are issued. *2: Until the S-VOL receives a Write command, the pair status of S-VOL is not changed to SSWS.
