How to Remove a Storage System

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

This procedure defines Node N as the node that is connected to the storage system 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 system that you are removing.

Before You Begin

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, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

To perform this procedure, become superuser or assume a role that provides solaris.cluster.modify 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 system 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 system.

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 system.
