To Unconfigure an HA Symmetric Deployment

Unconfiguring is done when you need to upgrade the Messaging Server or the Sun Cluster, or when you need to uninstall the Messaging Server. It is assumed that the system was configured the using the previous example.

The first step is to remove each resource group in the cluster. In the example, there are two resource groups, MS_RG_MARS and MS_RG_VENUS. Both must be removed.

1. Remove resource group MS_RG_MARS from the cluster.

   Use the following commands on just one node. You do not have to do this on each node.

   1. Brings the resource group off-line on all nodes of the cluster:

      # scswitch -F -g MS_RG_MARS

   2. Disable all the specific Messaging Server resources:

      # scswitch -n -j ms-rs-mars # scswitch -n -j meadow # scswitch -n -j ms-hasp-mars

   3. Remove all the specific MS resources:

      # scrgadm -r -j ms-rs-mars # scrgadm -r -j meadow # scrgadm -r -j ms-hasp-mars

   4. Remove the resource group:

      scrgadm -r -g MS_RG_MARS

2. Remove resource group MS_RG_VENUS from the cluster.

   Use the following commands on just one node. You do not have to do this on each node.

   1. Brings the resource group off-line on all nodes of the cluster:

      # scswitch -F -g MS_RG_VENUS

   2. Disable all the specific Messaging Server resources:

      # scswitch -n -j ms-rs-venus # scswitch -n -j pasture # scswitch -n -j ms-hasp-venus

   3. Remove all the specific MS resources:

      # scrgadm -r -j ms-rs-venus # scrgadm -r -j pasture # scrgadm -r -j ms-hasp-venus

   4. Remove the resource group:

      scrgadm -r -g MS_RG_VENUS

3. Unregister the Resource Types that are not in use.
