15.3 Deporting the CSM Containers with Segment Managers

If a resource’s CSM container does not have a segment manager, it contains a single volume, and the CSMPORT utility automatically converts the volume to a compatibility volume and deports the CSM container. If a resource’s CSM container has a segment manager on it, you must manually convert the Linux POSIX volumes in the container to compatibility volumes, and then deport the container by using the EVMS GUI. Special handling is also required to convert the scripts for CSM resources with a segment manager on them.

IMPORTANT:A CSM container must have its volumes converted and be deported in order to work in compatibility mode on OES 11x nodes.

Having a segment manager on the CSM container is not a typical configuration. In an OES 2 cluster, you might have added a segment manager on a CSM container in order to be able to create multiple volumes in the container as described in Adding a Segment Manager to the CSM Container in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux.

Check each of the CSM containers to determine if it contains a segment manager, and if it does, how many volumes it contains. If a resource’s CSM container contains a segment manager, convert the container’s volumes to compatibility volumes, then deport the container. If a resource’s CSM container does not contain a segment manager, continue with Section 15.4, Modifying the Scripts for CSM Resources without a Segment Manager.

Before you add OES 11x nodes to an OES 2 SP3 cluster, perform the following for each CSM cluster resource:

  1. Log in as the root user on the OES 2 SP3 server in the cluster where the Linux POSIX volume cluster resource is online, then open a terminal console.

    If the resource is offline, log in to an OES 2 SP3 node in the resource’s Preferred Nodes list, then bring the resource online by entering

    cluster online <resource_name>
  2. Launch the EVMSGUI utility by entering

  3. Check to see if the CSM container has a segment manager on it, then do one of the following:

  4. Convert each volume in the CSM container to a compatibility volume:

    1. Select the Volumes tab.

    2. Unmount the volume.

    3. Right-click the volume and select Convert to Compatibility Volume.

    4. Click Convert.

    5. Click Save to save all of the changes.

    6. Repeat Step 4.a through Step 4.e for each volume in the CSM container.

  5. Modify the CSM container’s properties to set its type to Deported:

    1. Select the Containers tab.

    2. Right-click the container and select Modify Properties.

    3. Select the container, then click Next.

    4. Select Type and change it to Deported.

    5. Click Modify, then click OK to confirm the change.

    6. Click Save to save the container type change.

  6. Repeat the previous steps for each CSM resource in the OES 2 SP3 cluster that manages a clustered Linux POSIX volume.

  7. Continue with Section 15.5, Modifying the Scripts for CSM Resources with a Segment Manager.
