Unmounting volumes

To unmount cartridges or volumes, the unmount command must be used. Without specifying the -d or -t option, the unmount command is only able to unmount volumes that were previously mounted with TSLM. Therefore, there must be Task and MountLogical objects present in the TSLM database that reflect a successful mount operation.

Verifying successful execution of unmount commands

Successful execution of an unmount command deletes the following objects:

• The MountLogical object that was created by the mount command
• The Task object that was created by the mount command

Additionally, a DriveCartridgeAccess object is created, which acts as status information about the previous mount/unmount operation. You can use the lsdca command to list these objects.
