9.6 Enabling Linux POSIX File Systems to Run on Secondary Clusters

If you are using Linux POSIX* file systems in cluster resources on the clusters in your BCC and you want to migrate or fail over those file systems to peer clusters, you must add a script to convert the EVMS CSM (Cluster Segment Manager) container for the file system. Without the script, the file system cannot be mounted and the cluster resource cannot be brought online on another cluster.

NOTE:The script is necessary only for Linux POSIX file systems, and not for NSS pools.

  1. Start your Internet browser and enter the URL for iManager.

    The URL is http://server_ip_address/nps/iManager.html. Replace server_ip_address with the IP address or DNS name of the server that has iManager and the Identity Manager preconfigured templates for iManager installed.

  2. Specify your username and password, specify the tree where you want to log in, then click Login.

  3. In Roles and Tasks, click Clusters, then click the Cluster Options link.

  4. Specify a cluster name, or browse and select one.

  5. Under Cluster Objects, select the business-continuity-enabled cluster resource that contains the Reiser or Ext3 file system, then click Details.

    Cluster resources that are enabled for business continuity have the BCC label on the resource type icon.

  6. Click the Business Continuity tab, then click Storage Management.

  7. Under BCC Load Scripts, click New to bring up a wizard that lets you create a new script.

  8. In the wizard, specify the following information:

    • Name: Convert CSM container.

    • Description: Converts the EVMS Cluster Segment Manager (CSM) container so the specified container is available on the secondary cluster.

    • CIM Enabled: Ensure that this option is deselected (not checked).

    • Synchronous: Ensure that this option is selected (checked)

    See Step 7.b in Adding Storage Management Configuration Information for more information and descriptions of the information in the value fields.

  9. Under Script Parameters, click New, then specify the following:

    • Name: Specify the variable name as CONTAINER_NAME. This value is case-sensitive and should be entered as

      CONTAINER_NAME

    • Value: Specify the name of the EVMS CSM (Cluster Segment Manager) container. You assigned this name to the EVMS CSM container when you created it. This value is case-sensitive and should exactly match the container name.

  10. Using a text editor, copy and paste the bcc_csm_util.pl script into the Script Parameters text box.

    The script is located in the /nsmi_scripts/linux/ directory on the Business Continuity Clustering 1.2 CD or ISO image.

  11. Click Apply to save your changes.

  12. Repeat Step 1 through Step 11 for the peer clusters in your BCC.

    The information you provide in the steps should be unique for each cluster.
