If there is no write-enable ring on the tape, install one. Then attempt
the operation again.
If the reference code continues to occur, exchange the FRU. Run test
2 to verify the repair.
You have attempted to get access to the tape unit from the system
while the tape unit was not online. Press the Online button to put the
tape unit online. Then attempt the operation again.
If the reference code continues to occur, exchange the FRU. Run test
2 to verify the repair.
A tape is loaded and preventing the diagnostic from being run.

If the front door or the top cover is open, close it. Then attempt the
operation again.
If this reference code continues to occur, run test 88. The status
display will be blank if the doors are closed correctly. The word
DOOR will appear in the display if either the door or the top cover is
opened. If DOOR appears in the display when the door and top cover
are closed, exchange the FRUs as needed, and run test 88 after each
FRU is exchanged to verify the repair.

The tape unit cannot read a tape that has not been initialized or is not
written with the correct density. The tape must be initialized at 1600 or
6250 bits per inch. Also, the tape path may be dirty.
Clean the tape path; see "Cleaning Procedure" on page 4-3. Run test
150 and 177 to verify the repair. If this reference code continues to
occur, exchange the readlwrite card and run test 162 to verify the
repair.

The tape unit cannot write on the tape. Ensure that the tape is at BOT
and attempt the operation again.
If this reference code continues to occur, exchange the tape sensor
card and attempt writing from the system to verify the repair. If the
reference code continues to occur, exchange the remaining two FRUs
as needed; and run test 151 after each of these FRUs is exchanged to
verify the repair.

The tape was already at BOT when a backspace command was sent
from the system
to
the tape unit. This is not permitted.
If this did not occur, exchange the FRU and attempt the operation
again. If the reference code continues to occur, contact your next
level of support.
