Upgrading From HAStorage to HAStoragePlus

HAStorage might not be supported in a future release of Sun Cluster software. Equivalent functionality is supported by HAStoragePlus. For instructions for upgrading from HAStorage to HAStorage, see the subsections that follow.

ProcedureHow 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.

Steps

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


    # 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. Register the HAStoragePlus resource type.


    # scrgadm -a -t SUNW.HAStoragePlus

  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

ProcedureHow 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
