How to Remove a Dual-Controller Configuration

Use this procedure to remove a dual-controller configuration from a running cluster.
This procedure defines

Node A

as the node with which you begin working.

Node B

another node in the cluster.

Caution –

During this procedure, you lose access to the data that resides on each

partner group that you are removing.

1. If necessary, back up all database tables, data services, and volumes that are

associated with each partner group that you are removing.

2. If necessary, detach the submirrors from each storage array or partner group that

you are removing. Detach the submirrors to stop all I/O activity to the storage
array or partner group.

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

3. Remove references to each LUN. This LUN belongs to the storage array or

partner group that you are removing.

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

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

Record this information because you use this information in

Step 19

of this

procedure to return resource groups and device groups to these nodes.

scstat

5. Shut down

Node A

For the procedure about how to shut down and power off a node, see your Sun
Cluster system administration documentation.

6. Disconnect from both storage arrays the fiber-optic cables that connect to the FC

switches. Then disconnect the Ethernet cables.

7. Is any storage array that you are removing the last storage array that is connected

to an FC switch that is on

Node A

■

If no, skip to

Step 11

■

If yes, disconnect the fiber-optic cable between

Node A

and the FC switch

that was connected to this storage array.

For the procedure about how to remove a fiber-optic cable, see the
