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.
Caution - During this procedure, you lose access
to the data that resides on the storage system that you are removing.
If necessary, back up all database tables, data services, and volumes that are associated with each partner group that is affected.
Remove references to the volumes that reside on the storage system that you are removing.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Disconnect the cables that connected Node N to the FC switches in your storage system.
On all nodes, remove the obsolete Solaris links and device IDs (DIDs).
# devfsadm -C # scdidadm -C
Repeat Step 3 through Step 4 for each node that is connected to the storage system.
How to Replace a Node-to-Switch Component
Use this procedure to replace the following node-to-switch components in a running cluster.
Node-to-switch fiber-optic cable
FC host adapter
FC switch
GBIC or an SFP
On the node that is connected to the node-to-switch connection that you are replacing, determine the resource groups and device groups that are running on this node.
# scstat
Move all resource groups and device groups to another node.
# scswitch -S -h from-node
Replace the node-to-switch component.
For the procedure about how to replace a fiber-optic cable, see the Sun StorEdge 6320 System Reference and Service Manual.
For the procedure about how to replace an FC switch, see the documentation that shipped with your FC switch hardware.
For the procedure about how to replace an FC host adapter, see your host adapter documentation.
For the procedure about how to replace GBIC or an SFP, see your switch documentation.
Return the resource groups and device groups that you identified in Step 1 to the node that is connected to the node-to-switch connection that you replaced.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
How to Replace a Host Adapter
Use this procedure to replace a failed host adapter in a running cluster. This procedure defines Node N as the node with the failed host adapter that you are replacing.
Determine the resource groups and device groups that are running on all nodes.
Record this information because you use this information in Step 9 of this procedure to return resource groups and device groups to these nodes.
# scstat
Move all resource groups and device groups off Node N.
# scswitch -S -h from-node
Shut down Node N.
For the procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.
Power off Node N.
For more information, see your Sun Cluster system administration documentation.
Replace the failed host adapter.
For the procedure about how to remove and how to add host adapters, see the documentation that shipped with your nodes.
Power on and boot Node N into noncluster mode.
For more information about how to boot nodes, see your Sun Cluster system administration documentation.
If necessary, upgrade the host adapter firmware on Node N.
See the Sun Cluster release notes documentation for information about accessing Sun's Info Docs on http://sunsolve.sun.com. The Info Docs list information about required patches and firmware that are available for download. For the procedure about how to apply host adapter firmware, see the firmware patch README file.
Boot Node N into cluster mode.
For more information about how to boot nodes, see your Sun Cluster system administration documentation.
Return the resource groups and device groups that you identified in Step 1 to the original nodes.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
For more information, see your Sun Cluster system administration documentation.
