How to Reconnect the Node to Shared Storage

1. Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

2. (Optional) If necessary, detach the submirrors on the storage array.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

3. Disconnect the SCSI terminator. Reattach the SCSI cable between the storage array and Node A.

   ---

   Caution –

   Connect this storage array to the same host adapter that the storage array was connected before you disconnected the SCSI cable.

4. Boot Node A into cluster mode.

   For the procedure about booting cluster nodes, see Chapter 3, Shutting Down and Booting a Cluster, in Sun Cluster System Administration Guide for Solaris OS.

5. If you detached submirrors in Step 1, reattach the submirrors on the storage array. Wait for the submirrors to resynchronize.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

6. Repeat Step 1 through Step 5 for the remaining storage array that you want to reconnect to Node A.

7. (Optional) If you moved device groups off the node in Step 4 of the disconnect procedure, move all device groups back to the node.

   Perform the following step for each device group you want to return to the original node.

   • If you are using Sun Cluster 3.2, use the following command:

     # cldevicegroup switch -n NodeA devicegroup1[ devicegroup2 ...]

     -n NodeA

     The node to which you are restoring device groups.

     devicegroup1[ devicegroup2 ...]

     The device group or groups that you are restoring to the node.

   • If you are using Sun Cluster 3.1, use the following command:

     # scswitch -z -D devicegroup -h NodeA

8. (Optional) If you moved resource groups off the node in Step 4 of the disconnect procedure, move all resource groups back to the node.

   Perform the following step for each resource group you want to return to the original node.

   • If you are using Sun Cluster 3.2, use the following command:

     # clresourcegroup switch -n NodeA resourcegroup1[ resourcegroup2 ...]

     -n NodeA

     For failover resource groups, the node to which the groups are returned. For scalable resource groups, the node list to which the groups are returned.

     resourcegroup1[ resourcegroup2 ...]

     The resource group or groups that you are returning to the node or nodes.

   • If you are using Sun Cluster 3.1, use the following command:

     # scswitch -z -g resourcegroup -h NodeA
