Rebuilding an MIR

Rebuilding an MIR
This section discusses the rebuilding of the MIR. This is an abnormal situation as the
tape drive automatically builds and changes the MIR as the tape is used. The rebuild
process is only used in the event that the MIR on a tape becomes damaged or
corrupted.
Note –
Make sure the write protect switch on the data cartridge is set to the Unlocked
position.
Operator Panel MIR Rebuilds
This process rebuilds an MIR from the rack mount drive tray operator panel.
1. Set the drive to the offline state.
(see “Place the Drive Offline (Operator Panel)” on page 41 , if required)
2. Press the Menu button until
Drv Menu?
appears in the display window.
3. Press the Select button (Yes) once.
The display window now shows the beginning of drive utilities submenus.
4. Press the Menu button until Build MIR appears.
5. Press the Select button to begin the MIR rebuilding process.
Ld Cust Tp appears in the display window.
Note – Any loaded cartridge unloads at this time.
If present, remove any unloaded cartridge.
6. Insert a cartridge with a defective MIR.
(see “Load a Cartridge” on page 46 , if required)
Note – Rebuilding an MIR could take 90 minutes (T10000A formatted cartridge) or
longer (T10000 B formatted cartridge) for a full data cartridge. When the rebuild is
complete, the cartridge unloads.
Caution – Tape damage : Any resistance to removing the cartridge, beyond the usual
friction between the data cartridge case and the tape drive, probably indicates that the
leader is not fully rewound.
If you believe the leader is not fully rewound, attempt another load operation by
pushing the cartridge back into the tape drive. If it loads OK, use the tape operator
panel
Unload
button to attempt an unload operation. Should that fail to correct the
situation, contact your service representative about a possible stuck cartridge. Do not
forcibly remove a cartridge .
