CMMVC9197E Cloud snapshot and restore operations are not allowed because of a generation delete abandon. Use rmvolumebackupgeneration to retry the delete operation.
Explanation
A previous generation delete operation was abandoned. You must complete this operation before further snapshot or restore operations can be run.
User response
Rerun the abandoned generation delete operation for the volume. When the operation is complete, new snapshot and restore operations are possible. Use the management GUI or the lsvolumebackupgeneration and rmvolumebackupgeneration commands to list and remove snapshot generations.
