How to Upgrade From HAStorage With CFS to HAStoragePlus With Failover File System

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 HAStorage resource.

Steps

1. Remove the dependencies the application resource has on HAStorage resource.

   # scrgadm -c -j nfsserver-rs -y Resource_Dependencies=""

2. Disable the HAStorage resource.

   # scswitch -n -j nfs1storage-rs

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

   # scrgadm -r -j nfs1storage-rs

4. Unregister the HAStorage resource type.

   # scrgadm -r -t SUNW.HAStorage

5. Modify /etc/vfstab to remove the global flag and change “mount at boot” to “no”.

6. 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.

     # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \ SUNW.HAStoragePlus -x FilesystemMountPoints=/global/nfsdata -x \ AffinityOn=True

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

     # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \ SUNW.HAStoragePlus -x GlobalDevicePaths=nfsdg -x AffinityOn=True

7. Enable the HAStoragePlus resource.

   # scswitch -e -j nfs1-hastp-rs

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

   # scrgadm -c -j nfsserver-rs -y \ Resource_Depencencies=nfs1=hastp-rs
