A tape drive head with abrasive particles can permanently damage a new
tape. A worn tape may leave abrasive particles in the tape drive head.
Follow the tape head cleaning instructions that appear at the end of the
test descriptions for TAPE.
2.
Avoid saving translations or announcements
on the backup tape cartridge
if all other Tape Drive and Host Adapter problems have not been resolved.
If there is something wrong with the Mass Storage System, an attempt to
save translations or announcements could destroy a good copy of the files
on the tape cartridge.
3. In a system configured with duplicated SPEs, the tests run on the standby
Tape circuit pack are identical to those run on the active Tape circuit pack.
Communications between the active and standby SPEs is provided by the
DUPINT circuit pack for both the control channel and memory shadowing.
Therefore, problems with the DUPINT circuit pack may affect maintenance
tests of the standby Tape circuit pack.
4. Check the error log for power related problems and refer to the
maintenance documentation on power.
5. The
data on the tape cartridge will likely be destroyed
if:
■ The tape cartridge is removed when the amber LED on the Tape
circuit pack is on.
■ The Tape circuit pack is removed while the amber LED on the Tape
Circuit is on.
■ Power is removed from the Tape Drive while the amber LED on the
Tape circuit pack is on.
6. The
data on the disk will likely be destroyed
if the Tape circuit pack is
removed while the amber LED on the Disk Drive is on.
7. Dirty Tape Drive heads may cause problems that appear to be hardware
related. To clean the tape heads in the Tape Drive, follow the tape head
cleaning procedure at the end of this section.
8. Since maintenance software cannot always distinguish between errors
caused by the tape cartridge and those caused by the Tape Drive or Host
Adapter, check for tape cartridge errors first.
■ Make sure there is a tape cartridge in the Tape Drive.
■ Make sure that the write protect lock is not active. To deactivate
write protect, slide the
RECORD
switch on the tape cartridge in the
direction of the arrow on the switch.
