How to Remove StorEdge 3900 or 6900 Series Systems From a Running Cluster

Use this procedure to permanently remove a StorEdge 3900 or 6900 Series system and its associated submirrors from a running cluster.

This procedure defines "Node A" as the cluster node you begin working with, and "Node B" as the other node.

During this procedure, you lose access to the data that resides on each StorEdge T3+ array partner-group in the StorEdge 3900 or 6900 Series system you are removing.

1. If necessary, back up all database tables, data services, and volumes associated with each StorEdge T3+ partner-group in the StorEdge 3900 or 6900 Series system you are removing.

2. If necessary, run the appropriate Solstice DiskSuite or VERITAS Volume Manager commands to detach the submirrors from each StorEdge T3+ partner-group in the StorEdge 3900 or 6900 Series system that you are removing to stop all I/O activity to the partner-groups.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

3. Run the appropriate Solstice DiskSuite or VERITAS Volume Manager commands to remove references to each LUN or VLUN in the StorEdge 3900 or 6900 Series system that you are removing.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

4. Determine the resource groups and device groups running on all nodes.

   Record this information because you will use it in Step 17 of this procedure to return resource groups and device groups to these nodes.

   # scstat

5. Move all resource groups and device groups off Node A.

   # scswitch -S -h nodename

6. Shut down Node A.

   # shutdown -y -g0 -i0

   For the procedure on shutting down a node, see the Sun Cluster 3.0 12/01 System Administration Guide.

7. Disconnect the cables that connected Node A to the FC switches in your StorEdge 3900 or 6900 Series system.

8. Without allowing the node to boot, power on Node A.

   For more information, see the Sun Cluster 3.0 12/01 System Administration Guide.

9. Boot Node A into cluster mode.

   {0} ok boot

10. Move all resource groups and device groups off Node B.

    # scswitch -S -h nodename

11. Shut down Node B.

    # shutdown -y -g0 -i0

12. Disconnect the cables that connected Node B to the FC switches in your StorEdge 3900 or 6900 Series system.

13. Without allowing the node to boot, power on Node B.

    For more information, see the Sun Cluster 3.0 12/01 System Administration Guide.

14. Boot Node B into cluster mode.

    {0} ok boot

    For more information, see the Sun Cluster 3.0 12/01 System Administration Guide.

15. On all nodes, update the /devices and /dev entries.

    # devfsadm -C # devfsadm

16. On all nodes, update the paths to the DID instances

    # scdidadm -C # scdidadm -r

    .

17. Return the resource groups and device groups you identified in Step 4 to all nodes.

    # scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
