You can use the command-line interface (CLI) to remove MDisks from the clustered system (system).
When you remove LUs from your storage system, the managed disks (MDisks) that represent those LUs might still exist in the system. However, the system 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.
To remove MDisks:
All of the MDisks that represent unconfigured LUs are removed from the system.
