V-76-58645-598 "The specified disk is not empty, operation not allowed" when removing disk from Veritas Dynamic Diskgroup

Problem

When attempting to remove a disk from a diskgroup, the "Remove Disk from Dynamic Diskgroup" fails.

Error Message

Error V-76-58645-598
The specified disk is not empty, operation not allowed.

Cause

This error appears when attempting to remove the disk from the diskgroup while it still holds a subdisk/plex for a volume from the diskgroup. 

Solution

1) If the volume present on the problem disk is no longer required, then delete the volume and try the operation again.

2) If the disks owns subdisk(s) which belongs to a volume that cannot be deleted then perform a "move subdisk" to move all subdisks from that disk to any one of the existing disks from the diskgroup.
