Upgrading from HAStorage to HAStoragePlus

HAStorage might not be supported in a future release of Sun Cluster. Equivalent functionality is supported by HAStoragePlus. To upgrade from HAStorage to HAStorage, see the following sections.

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

HAStorage might not be supported in a future release of Sun Cluster. Equivalent functionality is supported by HAStoragePlus. To upgrade from HAStorage to HAStoragePlus when using device groups or CFS, complete the following steps.

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

  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.

    To specify a filesystem mount point, input the following text.


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

    To specify global device paths, input the following text.


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

    Instead of using the ServicePaths property for HAStorage, you must use the GlobalDevicePaths or FilesystemMountPoints property for HAStoragePlus. The FilesystemMountPoints extension property must match the sequence specified in /etc/vfstab.

  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

How to Upgrade from HAStorage With CFS to HAStoragePlus With Failover Filesystem

HAStorage might not be supported in a future release of Sun Cluster. Equivalent functionality is supported by HAStoragePlus. To upgrade from HAStorage with CFS to HAStoragePlus with Failover Filesystem (FFS), complete the following steps.

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

  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.

    To specify a filesystem mount point, input the following text.


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

    To specify global device paths, input the following text.


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

    Instead of using the ServicePaths property for HAStorage, you must use the GlobalDevicePaths or FilesystemMountPoints property for HAStoragePlus. The FilesystemMountPoints extension property must match the sequence specified in /etc/vfstab.

  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
