Adding a disk drive enables you to increase your storage space after a storage array has been added to your cluster.
If the disk drive that you are adding was previously owned by another controller module, reformat the disk drive to wipe clean the old DacStore information before adding the disk drive to this storage array. If any old DacStore information remains, it can cause aberrant behavior including the appearance of ghost disks or LUNs in the RAID Manager interfaces.
This procedure relies on the following prerequisites and assumptions.
Your cluster is operational.
Your storage array contains an empty disk slot.
Your nodes are not configured with dynamic reconfiguration functionality.
If your nodes are configured for dynamic reconfiguration, see the Sun Cluster system administration documentation and skip steps that instruct you to shut down the node. For a list of Sun Cluster documentation, see Related Documentation.
Verify that the new disk drive is formatted.
For information about how to move drives between storage arrays, see the Sun StorEdge RAID Manager Release Notes.
Install the new disk drive to the storage array.
For the procedure about how to install a disk drive, see your storage documentation. For a list of storage documentation, see Related Documentation.
Enable the disk drive to spin up approximately 30 seconds.
Run Health Check to ensure that the new disk drive is not defective.
For instructions about how to run Recovery Guru and Health Check, see the Sun StorEdge RAID Manager User’s Guide.
Fail the new drive, then revive the drive to update DacStore on the drive.
For the procedure about how to fail and revive drives, see the Sun StorEdge RAID Manager User’s Guide.
To create LUNs for the new drives, see How to Create a LUN for more information.
