9.1 Cluster Migrating the Shared NSS Volume for the VLDB

Use this method if you want to use the same shared disk where the VLDB is currently stored.

  1. For each Linux node where you expect to run the VLDB service, install Novell Storage Services and any of its dependent services on the Linux node, then add it to the mixed cluster that you are converting.

  2. For each of the Linux nodes, assign the node’s nssadmin user as a trustee of the container that is configured as the Management Context for the VLDB, and give the user at least the Read and Compare rights to the [All Attribute Rights] property.

    IMPORTANT:If the Management Context is configured to use the container that contains a node’s Server object, the nssadmin User object for that server is already a trustee of the container and has the Supervisor right. Do not modify the existing rights settings for this nssadmin User object when you add rights for the [All Attribute Rights] property.

    1. In iManager, select Rights > Modify Trustees.

    2. Select the container that is configured as the Management Context, then click OK.

    3. Click Add Trustee, select the nssadmin User object, then click OK.

      The nssadmin User object is in the same container as its server. The user name format is servnameadmin.context. For example, if the server name is server1.ou1.mycompany, then server1admin.ou1.mycompany is the nssadmin user name.

    4. Click Assigned Rights for the selected nssadmin User object.

    5. Assign the Read and Compare rights to the [All Attribute Rights] property, then click Done.

    6. Click Apply to save and apply the changes.

    7. Repeat Step 2.c through Step 2.f for each of the Linux nodes where you expect to run the VLDB service.

  3. Cluster migrate the DFS cluster resource from NetWare to Linux.

  4. On the Linux node where the VLDB is active, offline the DFS cluster resource.

  5. Remove the NetWare clusters from the cluster by using the cluster leave command, then finish the cluster conversion.

    This automatically updates the basic cluster commands in the cluster resource scripts.

  6. Using the Clusters plug-in in iManager, modify the load script of the DFS cluster resource to change the vldb command to the Linux format. For example, change it from

    vldb /dir=vldbpath

    to

    vldb -dir /vldbpath

  7. Online the cluster resource.

  8. Run a VLDB repair to ensure that the database is correct.
