1 Preparing to install HP EVA Cluster Extension This chapter provides information about general environment considerations and pre-installation requirements. Ideal environment The ideal configuration environment consists of at least five servers (two at each data center site and one as an arbitrator at a third site) with separate, redundant communications links for cluster heartbeats, client access, and HP EVA Continuous Access.
Failover function HP EVA Cluster Extension Software requires cluster software to automatically fail over among systems on a local site or between sites. Because the software manipulates the application startup process before storage system vdisks are accessed, it must be integrated as the first resource (in the order of resources). The software must be installed on all servers in the cluster that can run the application service.
Figure 1 Zoning example Disk space and system memory requirements • 50 MB for the HP EVA Cluster Extension installation directory (%ProgramFiles%\ Hewlett-Packard\Cluster Extension EVA) • At least 25 MB of system memory Required firmware and software For specific firmware and software versions, see the HP SPOCK website: http://www.hp.com/ storage/spock.
2 Installing HP EVA Cluster Extension Software This chapter describes the HP EVA Cluster Extension installation in Failover Cluster (MSCS) environments with HP EVA disk arrays. This version of HP EVA Cluster Extension allows you to install, uninstall, modify, and repair HP EVA Cluster Extension on all of the nodes in a cluster by running the installer from one node in the cluster. This feature is not available for performing HP EVA Cluster Extension upgrade procedures.
to one of the storage systems. However, a connection to either storage system is not necessary for the node to act as a tiebreaker. • SAN fabrics can be extended to allow array-based data replication. Consult the HP EVA Continuous Access Implementation Guide and the HP SAN Design Reference Guide for supported SAN extension configuration and instructions on setting up your HP EVA Continuous Access environment.
Creating vdisks and adding a LUN presentation Create the storage (vdisks) for your application data using the SSSU or the P6000 Command View GUI, and then present the vdisks to the cluster nodes connected to that HP EVAarray. NOTE: At a later time in this installation process, you can create a LUN presentation for your remote destination vdisk and set the access mode property for the destination vdisk to read-only.
Creating DR groups Before you can use HP EVA Cluster Extension, you must create a DR group that includes your previously created vdisk(s). When you create the DR group with a local vdisk (or vdisks), a replica of the vdisk(s) on the remote destination storage system is created automatically. The disk pair is known as a DR group member or copy set. When you create a DR group, note the following: • Set Write mode to Synchronous or Asynchronous.
1. Before installing MSCS, create your disk configuration through the Disk Manager. If the disks are not visible, re-scan your disks in the Disk Manager. NOTE: You might need to shut down all except one server on the source storage system to successfully configure your disks in the Disk Manager. Errors might occur during partitioning and formatting because all servers on the local storage that are presented to the same disk compete to access the disk.
NOTE: • Installing the CLI is not required if you are using HP EVA Cluster Extension Software with MSCS. • If you are installing CLX product on a cluster whose nodes contain both Server Core and Non-Server Core, then you must install the CLX product from the Non-Server Core cluster node. To install HP EVA Cluster Extension: 1. Ensure that the cluster service is running. 2.
7. Select the cluster nodes for HP EVA Cluster Extension installation, and then click Next. The Choose Destination Location dialog box appears. 8. 14 Accept the default location, or click Browse and specify a new destination.
9. Specify whether the installation directory will apply to all nodes selected for installation: • If you want to use the same destination location for all nodes selected in the previous step, select the Use the same destination location for all the selected remote cluster nodes check box, and then click Next.
Upgrading HP EVA Cluster Extension Software This version of HP EVA Cluster Extension Software supports upgrading from version 4.00.01 or later. You can also upgrade HP EVA Cluster Extension concurrently with HP P6000 Command View. Use one of the following procedures: • “Upgrading from HP EVA Cluster Extension 4.00.01 or later (Windows Server 2008/2008 R2/2012)” (page 16) • “Upgrading from HP EVA Cluster Extension 5.00.
Resetting the DR group GUI display After the upgrade is complete, the HP EVA Cluster Extension resource configuration GUI displays a blank value for the DR group Write mode property for existing Cluster Extension EVA resources. HP EVA Cluster Extension works as expected even though the Write mode is not displayed in the GUI. If you want to view the correct Write mode value in the GUI, perform the following procedure: 1.
“Upgrading from HP EVA Cluster Extension 5.00.00 (Windows Server 2012)” (page 17) (Only Windows Server 2012). 4. 5. In the second data center, move all the cluster resources to a node in the first data center. Upgrade HP P6000 Command View on the management server in the second data center. Configure the same SMI-S user information that is being used, with the existing version of HP EVA Cluster Extension. For instructions, see your HP P6000 Command View documentation. 6.
Repairing the HP EVA Cluster Extension installation Once HP EVA Cluster Extension is installed, you can repair the installation. 1. Start the HP EVA Cluster Extension InstallShield wizard: a. Depending on your version of Windows, perform one of the following steps: b. • For Windows Server 2008/2008 R2/2012: Select Start→Control Panel→Programs and Features. • For Server Core or Hyper-V Server: Run the HP EVA Cluster Extension installation package from the command line. Continue to Step 2.
7. Click OK. The install wizard checks if you want to unregister the cluster resource type from all the nodes in the cluster. HP recommends that you do not unregister the cluster resource type until you are uninstalling HP EVA Cluster Extension from the last node in the cluster. Execute one of the following operations: • If you have not unregistered the cluster resource type, and this is the last node in the cluster, click Yes.
NOTE: If cluster installation fails with the message Could not get the system drive for the cluster node... or Setup was unable to run the installation in remote machine..., confirm that the WMI service is running. To use the HP EVA Cluster Extension cluster-wide installation feature, the WMI service must be running. On Windows Server 2012, installation of the CLX product registers the CLX resource type, and registration of resource type copies the CLX resource DLL files clxevamscs.dll and clxevavmmscs.
Table 1 Windows remote installation error codes (continued) ERROR code Description Corrective action used instead of cluster.exe to perform the registration. For more information, see Microsoft documentation. ERROR_CLXMSCSEX_REGISTER_FAILED Installation completed on the local cluster node. Register the resource extension DLL by running the following cluster command: Setup was unable to register the Cluster Cluster / regadminext:clxevamscsex.dll. Extension EVA DLL.

Setup was unable to register resource type Cluster Extension EVA for VM Management. Register the Resource type “Cluster Extension EVA for VM Management”.
2. Registration of resource extension DLL must not be performed on Server Core environments.
If the Cmdlet is registered, the following output is displayed: Name:CLXEVACmdletsSnapin PSVersion : 6.0 Description : This PowerShell SnapIn provides cmdlets to help you manage the CLX EVA with Microsoft Windows PowerShell. If the Cmdlet is not registered, then you have to manually register the Cmdlet DLL by running the following command from the CLX product bin directory: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe CLXEVACmdlets.
3 Licensing This chapter explains how to obtain and install the product license keys. A license key is required to use all of the product features. The License Entitlement Certificate provides instructions on how to obtain a license key. In the interim, a temporary, instant-on license key is available so that you can immediately start using all the features. The instant-on key is valid for 60 days from the first use.
Importing a license key from a file When you receive the license key file by email, import the license key by running the following command: clxautopass -addpasswords license file path Where license file path is the full (absolute) path name to the license key file. This command is equivalent to using the Install/Restore License Key from file option in AutoPass. Using the HP EVA Cluster Extension registration tool To install a license key: 1.
3. Select any installed instant-on license key and click Remove.
