Removing MDisks that represent unconfigured LUs using the CLI

You can use the command-line interface (CLI) to remove MDisks from the cluster.

When you remove LUs from your storage system, the managed disks (MDisks) that represent those LUs might still exist in the cluster. However, the cluster cannot access these MDisks because the LUs that these MDisks represent have been unconfigured or removed from the storage system. You must remove these MDisks.

Perform the following steps to remove MDisks:

Run the svctask includemdisk CLI command on all the affected MDisks.
Run the svctask rmmdisk CLI command on all affected MDisks. This puts the MDisks into the unmanaged mode.
Run the svctask detectmdisk CLI command. The cluster detects that the MDisks no longer exist in the storage system.

All of the MDisks that represent unconfigured LUs are removed from the cluster.
