How to Remove a Disk Drive From a StorEdge MultiPack Enclosure in Running Cluster

Use this procedure to remove a disk drive from a StorEdge MultiPack enclosure. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster 3.0 U1 System Administration Guide and your server hardware manual.

For conceptual information on quorum, quorum devices, global devices, and device IDs, see the Sun Cluster 3.0 U1 Concepts document.

1. Determine if the disk drive you want to remove is a quorum device.

   # scstat -q

   • If the disk drive you want to replace is a quorum device, put the quorum device into maintenance state before you go to Step 2. For the procedure on putting a quorum device into maintenance state, see the Sun Cluster 3.0 U1 System Administration Guide.

   • If the disk is not a quorum device, go to Step 2.

2. Perform volume management administration to remove the disk drive from the configuration.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

3. Identify the disk drive that needs to be removed and the slot from which the disk drive needs to be removed.

   If the disk error message reports the drive problem by DID, use the scdidadm -l command to determine the Solaris device name.

   # scdidadm -l deviceID # cfgadm -al

4. Remove the disk drive.

   For more information on the procedure for removing a disk drive, see the Sun StorEdge MultiPack Storage Guide.

5. On all nodes, remove references to the disk drive.

   # cfgadm -c unconfigure cN::dsk/cNtXdY # devfsadm -C # scdidadm -C
