How to Remove a StorEdge 9910/9960 Array

Use this procedure to permanently remove a StorEdge 9910/9960 array and its submirrors from a running cluster. This procedure provides the flexibility to remove the host adapters from the nodes for the StorEdge 9910/9960 array you are removing.

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

During this procedure, you will lose access to the data that resides on the StorEdge 9910/9960 array you are removing.

1. Back up all database tables, data services, and volumes that are associated with the StorEdge 9910/9960 array that you are removing.

2. Detach the submirrors from the StorEdge 9910/9960 array you are removing in order to stop all I/O activity to the array.

   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 the references to the LUN(s) from any diskset or disk group.

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

4. Determine the resource groups and device groups that are running on Node A.

   # scstat

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

   # scswitch -S -h from-node

6. Stop the Sun Cluster software on Node A, and shut down Node A.

   # shutdown -y -g0 -i0

   For the procedure on shutting down a node, see the Sun Cluster 3.0 U1 System Administration Guide.

7. Disconnect the fiber-optic cable between Node A and the StorEdge 9910/9960 array.

8. Do you want to remove the host adapter from Node A?

   • If no, skip to Step 11.

   • If yes, power off Node A.

9. Remove the host adapter from Node A.

   For the procedure on removing host adapters, see the documentation that shipped with your host adapter or updated information on the manufacturer's web site.

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

    For more information, see the documentation that shipped with your server.

11. Boot Node A into cluster mode.

    {0} ok boot

12. Determine the resource groups and device groups that are running on Node A.

    # scstat

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

    # scswitch -S -h from-node

14. Stop the Sun Cluster software on Node B, and shut down Node B.

    # shutdown -y -g0 -i0

15. Disconnect the fiber-optic cable between Node B and the StorEdge 9910/9960 array.

16. Do you want to remove the host adapter from Node B?

    • If no, skip to Step 19.

    • If yes, power off Node B.

17. Remove the host adapter from Node B.

    For the procedure on removing host adapters, see the documentation that shipped with your server and host adapter.

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

    For more information, see the documentation that shipped with your server.

19. Boot Node B into cluster mode.

    {0} ok boot

    For more information, see the Sun Cluster 3.0 U1 System Administration Guide.

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

    # devfsadm -C # scdidadm -C

21. Return the resource groups and device groups you identified in Step 4 to Node B.

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