How to Upgrade From HAStorage to HAStoragePlus When Using Device Groups or CFS

The following example uses a simple HA-NFS resource that is active with HAStorage. The ServicePaths are the disk group nfsdg and the AffinityOn property is True. Furthermore, the HA-NFS resource has Resource_Dependencies set to the HAStorage resource.

1. Bring offline the resource group nfs1-rg.

   # clresourcegroup offline nfs1-rg

2. Remove the dependencies the application resources has on HAStorage.

   # clresource set -p Resource_Dependencies="" nfsserver-rs

3. Disable the HAStorage resource.

   # clresource disable nfs1storage-rs

4. Remove the HAStorage resource from the application resource group.

   # clresource delete nfs1storage-rs

5. Unregister the HAStorage resource type.

   # clresourcetype unregister SUNW.HAStorage

6. Register the HAStoragePlus resource type.

   # clresourcetype register SUNW.HAStoragePlus

7. Create the HAStoragePlus resource.

   Note –

   Instead of using the ServicePaths property of HAStorage, you must use the FilesystemMountPoints property or GlobalDevicePaths property of HAStoragePlus.

   ---

   • To specify the mount point of a file system, type the following command.

     The FilesystemMountPoints extension property must match the sequence that is specified in /etc/vfstab.

     # clresource create -g nfs1-rg -t \ SUNW.HAStoragePlus -p FilesystemMountPoints=/global/nfsdata -p \ AffinityOn=True nfs1-hastp-rs

   • To specify global device paths, type the following command.

     # clresource create -g nfs1-rg -t \ SUNW.HAStoragePlus -p GlobalDevicePaths=nfsdg -p AffinityOn=True nfs1-hastp-rs

   The resource is created in the enabled state.

8. Disable the application server resource.

   # clresource disable nfsserver-rs

9. Bring online the nfs1-rg group on a cluster node.

   # clresourcegroup online nfs1-rg

10. Set up the dependencies between the application server and HAStoragePlus.

    # clresource set -p Resource_dependencies=nfs1-hastp-rs nfsserver-rs

11. Bring online the nfs1-rg group on a cluster node.

    # clresourcegroup online -eM nfs1-rg
