2 Introduction VMware vsphere 5.0 is a virtualization platform for building cloud infrastructures using existing IT assets and resources. vsphere 5.0 runs on the new VMware ESXi 5.0 architecture, which provides a smaller, more secure footprint than the ESX architecture it replaces. We offer a portfolio of VMware software products that integrate with vsphere 5.0 to take advantage of its new capabilities. New options let you modify the vsphere environment to meet your specific needs, as well as make it easy to deploy vsphere 5.0 on HP ProLiant servers. This paper provides instructions for deploying and updating VMware vsphere 5.0 on ProLiant servers. Deployment vsphere 5.0 has multiple options to deploy ESXi 5.0 in the configuration that best meets your requirements. vsphere 5.0 supports only the ESXi 5.0 hypervisor architecture, and vsphere 5.0 requires a vcenter host. You can use either an interactive or a scripted installation when installing ESXi software. ESXi 5.0 deployment location options You must install ESXi 5.0 before deploying vsphere 5.0. You can manually deploy ESXi 5.0 to a local hard drive, a local flash device, or a SAN and network attached storage. Local disk drive: You can configure ESXi5.0 to local SAS/SATA disk drives directly or to local drives attached behind a Smart Array Controller. Both Smart Array-attached and local SAS-attached drives provide drive health data for all local drives. If you use SATA drives without a Smart Array controller, local health data is not available. Using drives behind a Smart Array Controller lets you increase redundancy and improve data integrity with RAID capabilities. You can also use locally attached drives as data stores to host virtual machines. Deployment to a local flash device: You can install ESXi 5.0 to an HP-tested and certified USB drive key or a Secure Digital (SD) card. Using local flash devices for deployment lets you deploy servers that do not have local hard drives. You can access a list of approved devices from the HP ESXi 5.0 product page at Deployment to SAN or network attached storage: You can deploy ESXi 5.0 to SAN or network attached storage using iscsi, FC, or FCoE connectivity. The HP custom image available from the HP Online Depot includes the required NIC, iscsi, FC, and FCoE drivers. After deploying the image, you can use the same SAN or network attached storage as data stores to host virtual machines. ESXi 5.0 image options ESXi 5.0 offers different image options. You can set up either the VMware base image, an HP custom image, or your own custom image. An image profile defines what loads at boot time, and includes the base image, additional drivers, HP components, and other third-party components. VMware base image: The VMware base image includes the base ESXi 5.0 hypervisor and initial set of drivers. This image does not include server-specific management components, or new or updated drivers. You can use the VMware base image with a large number of ProLiant servers. If you choose to use the VMware base image, we recommend that you add HP management components to the image after initial installation of ESXi 5.0. For more information, see the Creating a custom image section later in this paper. 2

3 HP custom image: The HP VMware ESXi 5.0 Customized Image (HP custom image) offers the easiest method to deploy ESXi 5.0 on ProLiant servers. This image includes HP management tools, utilities, and drivers that allow easy deployment of a fully managed ProLiant server. The HP custom ISO image is available at Custom ISO image: You can create your own custom ISO image for deploying ESXi 5.0. To create a custom ISO image, use the VMware ESXi Image Builder to customize a VMware base image or HP custom image to include the vsphere Installation Bundles (VIBs) that you want to load at boot time. VIBs can include additional drivers, HP components, and other third-party components. Then, use the customized image profile to create your custom ISO image. VMware ESXi Image Builder The VMware ESXi Image Builder PowerCLI snap-in lets you create and edit image profiles and VIBs. This snap-in adds new cmdlets to and is included with ESXi PowerCLI. You can use these cmdlets to manage the software you deploy to your ESXi hosts, including creating custom images and adding HP custom bundles. The Image Builder PowerCLI cmdlets run on a Windows client. Image Builder PowerCLI cmdlets take image profiles and VIBs as input and then produce a different ISO image or ZIP file that contain the image profile and all the VIBs referenced by it. You can export the image profiles to an ISO image or offline depot ZIP file. Depots are locations where Image Builder can find installation components. An offline depot is typically a.zip file containing the installation files for a specific version of ESXi. The offline depot can contain the desired components you retrieve from the HP Online Depot. You can use the ZIP depot with vsphere Update Manager or the ESX command line interface (ESXCLI) software VIB commands to update or install images. You can also use image profiles in vsphere Auto Deploy to specify the software to provision ESXi hosts. For more information about ESXCLI commands, see We publish our own image profile in the HP Online Depot ( that defines all the components contained in the HP custom image and all the individual HP-specific components for use with Image Builder. The HP Online Depot also offers the individual HP-specific component bundles for use with Image Builder PowerCLI snap-in or direct deployment. If you want to create your own custom image profile, we recommend the following: Boot using an unchanged HP image profile. Start with the HP image profile and add or remove components as necessary. Optionally, you can start with the VMware base image, and then use Image Builder to customize the base image by adding driver and management components. Before deploying your image, use Image Builder to create an offline bundle ZIP and unzip it to a local depot. Auto Deploy and ESXi 5.0 The new vsphere 5.0 Auto Deploy feature lets you perform unattended installations of ESXi 5.0 on multiple ProLiant servers. Auto Deploy runs as a stateless operation, which is an execution mode that has no record of local installations of ESXi 5.0 and requires no local storage. Using Auto Deploy, you can specify the image to deploy and the hosts to provision with the image. Auto Deploy uses a PXE boot infrastructure along with vsphere host profiles to provision and customize hosts. You can deploy HP management components as part of the Auto Deploy option by including them in the image profile, which results in a fully managed HP server operating in stateless mode. The HP Online Depot offers HP-specific components for use with vsphere 5.0 Auto Deploy. 3

4 Auto Deploy stores the information in different locations for the ESXi hosts to provision. The rules that map machines to image profiles and host profiles initially specify information about the location of image profiles and host profiles. When a host boots for the first time, the vcenter Server system creates a corresponding host object and stores the information in the vcenter Server database. Install the tools for Auto Deploy on the same server as vcenter. VMware s Linux-based vcenter appliance also includes these tools. For more information, see For more information about using Auto Deploy, see the vsphere Installation and Setup Guide at installation-setup-guide.pdf. HP Online Depot The HP Online Depot is a web-based repository that hosts our vsphere 5.0 HP custom image profile and the individual components, bundles, and VIBs. The HP Online Depot bundles provide solutions for the management and configuration of HP servers. HP Online Depot contains: The HP custom image profile that specifies all the bundles in the HP custom ISO image HP ESXi 5.0 Management bundle Management Providers, HP Integrated Lights-Out (ilo) drivers, and HP Customer Replaceable Unit (CRU) drivers. HP ESXi 5.0 Utilities such as HPBOOTCFG (boot order configuration) and HPONCFG (remote ilo configuration) that you can remotely execute with ESXCLI HP ESXi 5.0 NMI bundle with the Non Maskable Interrupt (NMI) driver that writes NMI error source to the Insight Management Log (IML). You can use the HP custom image profile with: The VMware vsphere 5.0 Image Builder You can use the HP custom image profile to: Create custom images Create Auto Deploy image profiles You can use the components with: The VMware vsphere 5.0 Image Builder The VMware Update Manager (VUM) The ESX command line interface You can use the components to: Add to Auto Deploy image profiles Update existing systems The HP Online Depot offers browser-based directory listings that let you copy components for alternative use cases. For example, if you require use of specific software we have yet to include in our mainstream bundles or images, you might need to include directories that contain special bundle zip files with VIBs until we permanently integrate them. 4

5 The HP custom image is available at The HP Online Depot is available at HP Online Depot use cases Examples of how to use HP Online Depot include: Use vsphere 5.0 Image Builder to connect to HP Online Depot, and then customize your image by adding or removing bundles. For example: Connect to HP Online Depot using the Image Builder PowerCLI command Add-EsxSoftwareDepot to and then add the HP-specific bundles using the Add-EsxSoftwarePackage command. Use vsphere Update Manager (VUM) to connect to HP Online Depot and apply the contents of a specific bundle to a custom image. For example: Directly connect VUM to HP Online Depot ( or to a specific bundle subdirectory on HP Online Depot ( Use VUM to compare versions in the depot with deployed versions, and then update the contents of the bundle as needed. Manually copy content from HP Online Depot to your local VMware depot or directly to a host. When using a local depot, you do not need Internet access from VUM. You can also use ESXCLI commands (for more information, see vmware.vcli.ref.doc_50/esxcli_command.html) to apply the contents of a bundle to a host. For example: To download bundles to use with VUM, manually copy the contents of HP Online Depot ( to your local VMware depot. Use VUM to apply the contents of the bundle from your local VMware depot to the host. To download bundles to use with ESXCLI, manually copy the contents of HP Online Depot ( or a specific bundle on HP Online Depot ( to either your local management console or the host. Use ESXCLI commands to deploy the bundle to the host. Note that you must always use the full path name when executing a ESXCLI command. A typical directory on HP Online Depot has the following structure and includes the following elements: HP_EULA.htm End User License Agreement index.xml Image Builder default index file that points to vendor-index.xml (available in main and each bundle directory) vendor-index.xml Lists product ID, version number and points to the hp-esxi metadata.zip (available in main and each bundle directory) hp-esxi metadata.zip A collection of VIB xml files along with the Image Profile that defines the initial image /hp-esxi5.0x-bundle Contains the HP Management Providers 5

6 /hp-hputil-esxi5.0-bundle Contains the HP Utility Bundle /hp-nmi-esxi5.0-bundle Contains the HP NMI Driver Using HP Online Depot to create a custom image This section describes the process for accessing VMware and HP Online Depot, then creating a new custom image (an ISO file) for ESXi 5.0 that includes the HP Management Providers and the HP ilo and HP CRU drivers. The custom image is stored locally. You can use it as a new template for ProLiant server installations. We assume that the following components have been installed: Windows PowerShell VMware PowerCLI/Image Builder snap in NOTE The HP custom image profile provides everything listed in the following procedure, plus the utilities, NMI driver, and up-to-date storage and networking drivers for the HP ProLiant servers. The process for creating a customized image includes using the vsphere 5 Image Builder tool and connecting to the VMware and HP Online Depot. Then, adding the HP Management, ilo, and CRU drivers into a clone of the VMware base image profile. This process creates a new custom integrated ISO. The following steps detail the commands necessary to create a custom image. 1. Start a VMware PowerCLI session by double-clicking on its icon. 2. Display the PowerCLI and Snap-in version information. Type PowerCLI > Get-PowerCLIVersion 3. Make a directory for the custom image. Type PowerCLI > md c:\myimage 4. Link to the VMware depot. Type PowerCLI > Add-EsxSoftwareDepot 5. Link to HP Online Depot. Type PowerCLI > Add-EsxSoftwareDepot 6. List the image profiles. Type PowerCLI > Get-EsxImageProfile 7. List the software packages. Type PowerCLI > Get-EsxSoftwarePackage Vendor Hewlett-Packard 8. Assign the specified ESXi Standard Image Profile to the $iptmp variable. Type $iptmp = Get-EsxImageProfile Name ESXi standard 9. Display the $iptmp variable list. Type PowerCLI > $iptmp format-list 6

7 10. Create a clone of the ImageProfile. Type PowerCLI > $ip = New-EsxImageProfile CloneProfile $iptmp Name Example: ESXi_5.0_ImageProfile Description Example_ImageProfile 11. Display the cloned ImageProfile variable. Type PowerCLI > $ip format-list 12. Add the hp-smx-provider software package or VIB. Type PowerCLI > Add-EsxSoftwarePackage ImageProfile $ip SoftwarePackage hp-smx-provider 13. Add the hpcru software package or VIB. Type PowerCLI > Add-EsxSoftwarePackage ImageProfile $ip SoftwarePackage char-hpcru 14. Add the hpilo software package or VIB. Type PowerCLI > Add-EsxSoftwarePackage ImageProfile $ip SoftwarePackage char-hpilo 15. List the HP VIB packages. Type PowerCLI > $ip.viblist more 16. Create the ISO file. This may take a few minutes. In this example, the ISO file is named Example_ESXi_5.0_image.iso. Type PowerCLI > Export-EsxImageProfile ImageProfile $ip ExportToISO Filepath c:\myimage\example_esxi_5.0_image.iso 17. Display the new ISO file. Type PowerCLI C:\Program Files (x86)\vmware\infrastructure\vsphere PowerCLI> dir c:\myimage Creating and deploying HP custom images The HP custom image profile provides an integrated, well-tested image. We test our customized images against all supported servers. Our tests include scenarios for updates and upgrades and for configuration changes. HP custom images simplify configuring and deploying ESXi 5.0 on ProLiant servers. You can use an HP custom image with any ProLiant server; however, certain servers require an HP custom image. For a list of servers that require a custom image, see the HP ProLiant Server VMware Support Matrix at Because of our testing, you will avoid the following installation issues when using an HP custom image: The inability to add or update components during the installation process The inability to install ESXi if a NIC driver for at least one NIC device does not load The inability to install ESXi to a SAN for a boot from SAN configuration if the required SAN device drivers are not in the ESXi installation image The inability to use Auto Deploy via a NIC device if the required NIC device driver is not in the ESXi installation image Key components of an HP custom image The HP custom image starts with the same base image that VMware provides to customers. We use VMware tools and processes to add the following components to the image: HP WBEM Providers, the HP ilo management driver, and HP CRU driver, which simplify deployment of a managed server 7

8 Required device drivers (NIC, FC, FCoE, iscsi, and storage), which enable installing the ESXi image on ProLiant servers with new network technology or options HP NMI driver, which will log NMI source into IML HP ESXCLI utilities: HPBOOTCFG and HPONCONFIG Two of the most critical components are the HP WBEM providers and boot from SAN drivers. HP WBEM Providers The HP custom image includes the HP WBEM providers, which are key components of a managed ESXi server. WBEM Providers allow a management client, such as HP Systems Insight Manager (SIM), to monitor and display information about server health. If you use the VMware base image, the HP WBEM providers are not included, resulting in extra installation steps to install them separately. SAN configuration One common implementation for ESXi is a boot from SAN configuration. Installing ESXi in this configuration means that the enabling device drivers must be available in the ESXi installation images. To simplify installing a boot from SAN configuration on ProLiant servers, we include the required drivers (FC, FCoE, and iscsi) for both embedded and supported optional devices that provide SAN connectivity. The result is a seamless process for setting up a boot from SAN ESXi environment on ProLiant servers. HP-custom image updates We release new custom ESXi images whenever there is a need to update any critical components of the image. VMware typically releases major, minor, or updated releases of ESXi several times a year. HP does not deliver a new custom image based on VMware patches or hot fixes. When we introduce a new server that needs a new or updated networking driver, we release a custom ESXi image that includes the drivers. You can get HP custom ESXi images from the HP Software Depot website: From this site, you can also download your required version of ESXi. Deploying and updating with HP Insight Control for VMware vcenter We are the first partner to integrate both physical and virtual management into VMware vcenter Server, which you can use to control and manage vsphere 5.0. vcenter Server performs the following tasks: Manages and provisions large numbers of ESXi hosts from either a physical or a virtual Windows machine. Stores and manages ESXi updates and patching through an image profile. Manages host configuration through a host profile. Uses Auto Deploy to load an ESXi image into host memory, downloads the image over the network when the host boots, and then executes the image out of RAM. Insight Control for VMware vcenter is a plug-in to vcenter Server that delivers HP hardware management capabilities to administrators. It enables comprehensive monitoring, remote control, and 8

9 power optimization directly from the vcenter console. Insight Control for VMware vcenter lets you manage multiple generations of HP servers. You can monitor your entire network as it leverages the industry s leading management tools from Insight Control. You can manage your virtualization environment from a single pane of glass from the vcenter console, including server, storage, and network infrastructure. Deploying hosts You can deploy ESXi hosts on bare-metal ProLiant servers directly from VMware vcenter using the new HP Insight Control Deployment Wizard. Available in the Home section of the vsphere client, the deployment wizard facilitates the HP RDP (Server Deployment) distribution. Insight Control for VMware vcenter lets you automatically add newly deployed hosts into the vcenter environment. This feature simplifies the deployment process compared to using RDP, in which you first deploy and then manually add the hosts to the vcenter environment. Insight Control for VMware vcenter brings deployment in to the environment you are already using. You do not have to leave the vsphere environment to perform a bare-metal deployment. NOTE You must have an HP SIM server and an RDP server to use the deployment feature in HP Insight Control for VMware vcenter. To use the HP Insight Control Deployment Wizard: 1. Navigate to the vsphere Client Home page. 2. Click HP Insight Control Deployment Wizard in the Management section. 3. In Step 1 Choose Targets window, select each system to which you want to deploy ESX/ESXi images, and click Next. 4. In Step2 Configure Networking window, do one of the following for each network adaptor shown below the listed systems: Select the DHCP check box. or Enter a static IP address, network domain, gateway, and DNS server information. 5. Click Next. 6. In Step 3 Deploy window, drag and drop the desired OS onto all or selected host systems, and then click Next. 7. In Step 4 Add to vcenter window, select the host systems you want to configure, enter the user names and passwords, select the cluster to which you want to add the system, and then click Next. 8. In Step 5 Summary window, monitor the status of the deployment and click the Finish button when the process is complete. Viewing firmware inventory and updating firmware The Firmware page in Insight Control for VMware vcenter lets you view firmware inventory and export to a CSV file, as well as update and manage smart components. To view firmware inventory information and update firmware for the selected cluster or server in the cluster, you must: 1. Log in to the vsphere Client. 2. Select a server or cluster in the inventory tree. 9

10 3. Click the HP Insight Software tab. 4. Click Firmware in the Server or Cluster Management section of the HP Management pane. 5. Select the Firmware Inventory tab to display the following: Server name or IP address Installed firmware-related component Firmware version Firmware manufacturer Component type (function) You can also generate a firmware inventory list in CSV file format by selecting Export to CSV. Update firmware using one of these methods: Enter the URL of a web server you have set up for downloading firmware updates. Use Insight Control for VMware vcenter to manage smart components. To update firmware for a cluster or selected systems in a cluster, complete the following steps: 1. Select the Smart Component Update tabbed page. 2. Select one of the following options: - Update from URL Type the URL of a web server from which to distribute the firmware update. - Update from Managed Smart Components Select one or more uploaded updates using the Managed Smart Components tabbed page. The Manage Smart Components capability lets you keep track of firmware versions on a host system by automatically inventorying firmware versions after you download them. To use the Manage Smart Components tabbed page, download smart components from and then upload the smart component files to Insight Control for VMware vcenter using the Managed Smart Components tabbed page. Customizing VUM for your HP servers VMware Update Manager (VUM) lets you upgrade and update software on a single or multiple ESXi hosts. This makes VUM the primary tool for keeping ESXi hosts current. Using the depots with VUM To use HP Online Depot and the VMware depot in VUM, add the depot URL to the VUM download source. You can configure the VUM download source in VUM from the Update Manager Admin View by selecting Configuration tab > Download Settings. By default, the main VMware depot is in the list of download sources. To add the HP Online Depot: 1. Click the Add Download Source link 2. Add the depot s main URL ( as shown in Figure Click OK to add the HP Online Depot to the Download Source list and set VUM to connect to the URL. 10

11 Figure 1: The VUM Download Settings Add Download Source dialog box lets you add download sources for future updates. Click the Download Now button to download all patches and upgrades available from the enabled sources (Figure 2). 11

12 Figure 2: The Configuration tab lets you select sources from which to download patches and upgrades. After the download is complete, you can find a list of downloaded patches and upgrades in the Patch Repository tab as shown in Figure 3. Figure 3: The Patch Repository tab lists downloaded patches and upgrades. 12

HP CIM Provider Bundle for Server Management HP Utility Bundle for Server Configuration HP NMI Driver Bundle for NMI Sourcing To install all HP Software Bundles available on ESXi 5.0 hosts, create a baseline that includes only the HP ESXi Depot Bundle as shown is Figure 4. For more detailed information about creating baselines, see Figure 4: The Baselines and Groups tab lets you install all HP Software Bundles. To install a specific HP Software Bundle, create a baseline that includes only that bundle (for example HP CIM Provider Bundle) and shown in Figure 5. For more detailed information about creating baselines, see 13

14 Figure 5: The Baselines and Groups tab lets you install a specific HP Software Bundle. Attach the data center or individual ESXi 5.0 hosts to the baseline. To upgrade the hosts with the HP Software Bundles for ESXi 5.0 included in the baseline, perform scan and remediate functions in the VUM Compliance View. Using VUM to keep HP servers up to date We recommend using the following procedures to keep HP servers updated with the latest patches from the depot. Configuring a download schedule With a download schedule, you can specify the download frequency, start time, and an address to receive notifications when the system downloads new patches. To configure the download schedule: 1. Go to VUM Admin View (Figure 6). 2. Select Configuration. 3. Select Download Schedule. 14

15 Figure 6: The Download Schedule link lets you configure the download schedule. Creating a dynamic baseline Creating a new dynamic baseline allows you to add downloaded patches that match the criteria you specify. This procedure adds the patches to the baseline. You can then attach your data center or selected HP ESXi hosts to this dynamic baseline. To create a new dynamic baseline: 1. Go to VUM Admin View. 2. Select Baselines and Groups (see Figure 7). 3. Select Create Baseline. 4. Under Baseline, type Host Patch. 5. Select Dynamic. 6. Select both the vendor names hp and Hewlett-Packard. 7. Under Criteria, leave Severity, Category, Product set to Any. The system lists the downloaded patches associated with the new dynamic baseline. 15

16 Figure 7: The Patch Details dialog box lets you create a new dynamic baseline. Scheduling tasks for a new dynamic baseline To create a scheduled task to schedule scans on the data center or selected ESXi hosts attached to the new dynamic baseline: 1. Go to vcenter Home. 2. Select Management. 3. Select Scheduled Tasks. 4. Select New. 5. Select Scan For Updates from the task selection pull-down list. 6. Specify update types, frequency, start time, and address for notification of results (Figure 8). Figure 8: The Schedule a Scan dialog box lets you create a scheduled task to schedule scans. 16

17 Scheduling remediate processes To create a task to schedule remediate processes for the data center of HP ESXi hosts: 1. Go to vcenter Home 2. Select Management. 3. Select Scheduled Tasks. 4. Select New. 5. Select Remediate from the task selection pull-down list. 6. Specify the HP Dynamic Patch Baseline and a time for the remediation process as shown in Figure 9. Figure 9: The Remediate dialog box lets you create a task to schedule remediate processes. You can configure all the scheduled tasks listed here to scan after the download completes. Also, the system will perform the remediate process after the scan completes. Or, you can manually create fixed baselines, perform scans and remediate tasks.
