Explanation: A request was made to delete a volume pool. The pool was not empty, or it could not be determined whether or not volumes were still associated with the specified volume pool.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Use a media management interface to query for the volumes that are associated with the pool specified for deletion. Ensure that all volumes in a volume pool are associated again with another pool before trying to delete the volume pool. Use change volume operations to change the volume pool for a volume.
