CMMVC8573E The action failed because there is one special volume owned by metadata volume in this storage pool.

Explanation

The rmmdiskgrp command failed even though the -force parameter was specified. One special volume in the specified storage pool is owned by the metadata volume.

User response

Complete the following steps:
  1. Run the lsmetadatavdisk command to find the special volume that is owned by the metadata volume.
  2. Either use the migratevdisk or addvdiskcopy/rmvdiskcopy commands to move the special volume from the specified storage pool to a different storage pool. (If vVols or metadata volume or both are no longer needed, run the rmmetadatavdisk command to remove.)
  3. Retry the rmmdiskgrp command.
