Replacing a Sun StorEdge A3x00 or Sun StorEdge A1000 Disk

The Sun Cluster sees Sun StorEdge A3x00 or Sun StorEdge A1000 disks as logical units (LUNs) and not as physical disks. Because of this:

• As long as the LUN is available, no action is necessary when replacing a failed physical disk.

• If the LUN is not available (or not in an optimal state) and was used as a quorum device, you need to use the scconf -q command to change the quorum device to a different LUN (disk) before proceeding with the disk replacement procedure.

For additional information regarding logical units and physical disks, refer to your expansion unit documentation. See also Chapter 3 and Chapter 9 in the Sun Cluster 2.2 Hardware Service Manual.

Note that some administrative procedures on the Sun StorEdge A3x00 or Sun StorEdge A1000s require replacement of UDWIS cards. For this procedure, see Chapter 12 in the Sun Cluster 2.2 Hardware Service Manual.
