How to Remove a Disk Drive From a StorEdge A5x00 Disk Array in a Running Cluster

Use this procedure to remove a disk drive from a StorEdge A5x00 disk array. "Example--Removing a StorEdge A5x00 Disk Drive" shows you how to apply this procedure. 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 are removing is a quorum device.

   # scstat -q

   • If the disk drive you are replacing 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 you are replacing is not a quorum device, go to Step 2.

2. If possible, back up the metadevice or volume.

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

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

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

4. Identify the disk drive that 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

5. On any node that is connected to the StorEdge A5x00 disk array, run the luxadm remove command.

   Physically remove the disk drive, then press Return when prompted.

   # luxadm remove -F /dev/rdsk/cNtXdYsZ

6. On all connected nodes, remove references to the disk drive.

   # devfsadm -C # scdidadm -C
