How to Attempt a Manual Dismount of a Tape Cartridge using ACSLS, HSC, or SLConsole

Fix

Before any physical intervention is attempted to remove a stuck tape, the following procedure should be followed to attempt to dismount the tape.

Attempt to dismount the cartridge via. ACSLS, HSC, and/or SL Console:

If the library is managed by ACSLS:
Issue a “dismount vol_id drive_id force” from the ACSLS cmd_ proc.
If you do not the cartridge’s vol_id, you can just enter a generic volser (e.g. X).

If the library is managed by HSC:
Dismount the cartridge via an HSC “DISMount volser devaddr ,, FORCE “ command.
Notes:
You can substitute a comma for the volser, e.g. “DISMount , devaddr ,, FORCE”.
You need the two commas between devaddr and FORCE. They indicate the optional host-id operand.

If the client is directly-attached to the library via the SCSI Media Changer interface over fibre, or the above attempts to dismount the cartridge via ACSLS or HSC did not work, do the following.

Dismount the cartridge via SL Console:
Select Diagnostics
Select the RcvrMove tab
After moving the cartridge, update the host’s database with the cartridge’s new location:
ACSLS – audit the LSM (or the panel, if you know it).
HSC – audit the LSM (or the panel, if you know it).
Fibre direct attached host – re-inventory the library.

Re-enter Good Cartridges Back into the Library
After the engineer has manually removed the cartridge from a tape drive, they should inspect it to see if it is damaged. If the cartridge is not damaged, ask the customer to re-enter it back into the library, so it is available for their use. When the cartridge is re-entered into the library, the customer needs to ensure that the host application is aware of the cartridge’s status and new location.

First, if the tape drive is now operational, insert it back into the library at its former location. This ensures that the library will not tell the controlling host that the cartridge is still in the tape drive. If you cannot re-insert the drive back into the library, you may/will have to logically delete the cartridge from the host’s database before re-entering the cartridge.

Please follow the appropriate procedure depending on whether the library is controlled by ACSLS, HSC, or a client application directly-attached via Fibre.

If the library is managed by ACSLS:
If you were unable to re-insert the tape drive back into the library, delete the volume from the ACSLS database with the del_vol utility with the force option (from the Unix command prompt):
    del_vol -f vol_id
Enter the cartridge back into the library.

If a CAP is in automatic mode, just open the CAP, insert the cartridge, and close the CAP.

Or, issue a manual enter:
      enter cap_id
     Open the CAP, insert the cartridge, and close the CAP.
     After ACSLS has entered the cartridge, cancel the enter.

If the library is managed by HSC:
Enter the cartridge back into the library.
If a CAP is in automatic mode, just open the CAP, insert the cartridge, and close the CAP.

Or, issue a manual enter:
      ENter cap_id
      Open the CAP, insert the cartridge, and close the CAP.
      After HSC has entered the cartridge, Drain the CAP:
               DRAin cap_id

If the client is directly-attached to the library via the SCSI Media Changer interface over fibre, or the above attempts to dismount the cartridge via ACSLS or HSC did not work, import the cartridge via the CAP.
