Unloading a Tape from a Drive
If a drive has failed or had an error, the following can happen:
• The icons on the library front panel indicate a drive error.
• The library attempts to take the drive offline.
• The host indicates an error and recommends taking the drive offline.
• The host automatically takes the drive offline (if supported).
Before replacing a drive, unload any tape from the drive (if applicable).
1. From the Drive and Tape Operations menu, select Unload Tape from
Drive .
2. Use the [-] or [+] keys to select the drive you want to unload.
3. Select [Unload] to move the tape from the drive module to the original
slot where the tape was located. The tape is automatically rewound
before it is unloaded.
4. If you are unable to unload a tape from a failed drive, follow the
procedure below.
Taking a Drive Offline
Although a drive module can be removed without powering off the
library, you must first take the drive module offline. This process may be
accomplished by using the library’s front panel and following these steps:
1. Check the drive icons on the front panel display to see if the drive has
already been taken offline. Verify the drive module’s status by
checking the LEDs on the back of the drive module (Table 4-10 on
page 4-26).
2. If the drive module is not already offline, go to the Administration and
then Online Drive Repair menus.
3. Select the drive with the [-] or [+] keys, and press [OK] .
4. Select Put Drive Offline . The front panel indicates the success or failure
of this operation.
