How to Remove a Storage Array

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

This procedure defines Node N as the node that is connected to the storage array you are removing and the node with which you begin working.

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

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, seeAppendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

Before You Begin

To perform this procedure, become superuser or assume a role that provides solaris.cluster.modify role-based access control (RBAC) authorization.

1. If necessary, 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 more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

3. 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 through Step 4 for each node that is connected to the storage array.
