How to Remove a Storage Array

Use this procedure to permanently remove a storage array from a running cluster.

During this procedure, you lose access to the data that resides on the storage array that you are removing. Back up the data before you proceed.

1. If you are using Sun Cluster Geographic Edition, you might need to back up all database tables, data services, and volumes that are associated with each partner group that is affected.

2. Remove references to the volumes that reside on the storage array that you are removing. For instructions, see How to Remove a Volume From a Device Group (VERITAS Volume Manager) in Sun Cluster System Administration Guide for Solaris OS.

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

3. If you have a Fibre Channel array, disconnect the cables that connected Node N to the FC switches in your storage array.

4. On all nodes, remove the obsolete Solaris links and device IDs.

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

     # devfsadm -C # cldevice clear

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

     # devfsadm -C # scdidadm -C

5. Repeat Step 3 and Step 4 for each node that is connected to the storage array.
