7.4 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 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 that were created on OES 2 systems and used EVMS Cluster Segment Manager containers. It is not used for clustered NSS pools or LVM volume groups.

  1. Log in to iManager as the BCC Administrator user.

  2. In Roles and Tasks, click Clusters > My Clusters, then click the cluster name.

  3. Click the Cluster Options tab.

  4. Under Cluster Objects, select the BCC-enabled cluster resource that contains the Linux file system, then click Details.

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

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

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

  7. In the wizard, specify the following information:

    • Name: Convert CSM container.

    • Description: Converts the 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 6.b in Adding BCC Load and Unload Scripts for more information and descriptions of the information in the value fields.

  8. 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

    • Value: Specify the name of the container. You assigned this name to the container when you created it. This value is case-sensitive and should exactly match the container name.

  9. 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 CD or ISO image.

  10. Click Apply to save your changes.

  11. Repeat Step 1 through Step 10 for each peer cluster in your BCC.

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