I would like to ask a question, if it's possible to use some king of PRE_CLONE_CREATE_CMD in Mount action. This command is lauched only in cloneLun or cloneVol action, not in Mount action.
What is my problem?
Customer creates clones from existing snapshots with Mount action. It works fine, but sometimes it would be very helpful if you can stop the action (in case of some errror) and exit with an error code/message forwarded to DFM before creating snapshot. In Umount action it's ok - PRE_UMOUNT_CMDs run before physical clone destroy. In Mount action, PRE_MOUNT_CMDs are running after the clone is created. It means that clone is created every time if Mount action is started and you have now change to break the clone creation process. And such "zombie" clones stay on the controller and cause problems in snapshot retentoin - snapshots are busy and can't be deleted.
