How to Remove a Disk Drive (Sun Cluster 3.1 - 3.2 With Fibre Channel JBOD Storage Device Manual)

Sun Cluster 3.1 - 3.2 With Fibre Channel JBOD Storage Device Manual

How to Remove a Disk Drive

For conceptual information about quorum, quorum devices, global devices, and device IDs, see your Sun Cluster concepts documentation. For a list of Sun Cluster documentation, see Related Documentation.

Example 1–5 shows you how to apply this procedure.

Before You Begin

This procedure assumes that your cluster is operational.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

To perform this procedure, become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization.

Determine whether the disk drive that you want to remove is configured as a quorum device?
- If you are using Sun Cluster 3.2, use the following command:
  # clquorum show
- If you are using Sun Cluster 3.1, use the following command:
  # scstat -q

If the disk drive you want to remove is configured as a quorum device, choose and configure another device to be the new quorum device. Then remove the old quorum device.

For procedures about how to add and remove quorum devices, see Sun Cluster system administration documentation.

If possible, back up the metadevice or volume.

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

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

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

Identify the disk drive that needs to be removed.

If the disk error message reports the drive problem by DID, determine the Solaris device name.
- If you are using Sun Cluster 3.2, use the following command:
  # cldevice list -v
- If you are using Sun Cluster 3.1, use the following command:
  # scdidadm -l deviceID

On any node that is connected to the storage array, run the luxadm remove_device command.

Remove the disk drive. Press the Return key when prompted.
# luxadm remove_device -F /dev/rdsk/cNtXdYsZ

On all connected nodes, remove references to the disk drive.
- If you are using Sun Cluster 3.2, use the following command:
  # devfsadm -C # cldevice clear
- If you are using Sun Cluster 3.1, use the following command:
  # devfsadm -C # scdidadm -C

Example 1–5 Removing a Disk Drive in a Sun StorEdge A5x00 Storage Array When Using Sun Cluster 3.2 Software

The following example shows how to remove a disk drive from a Sun StorEdge A5x00 storage array in a cluster running Sun Cluster version 3.2 software. The disk drive to be removed is d4 and is a virtual table of contents (VTOC) labelled device.

# cldevice list -v
