Tape Write Reference Codes

Ref.
Code
0044
One track was in error during a write operation. This problem may be
caused by a bad tape or a dirty tape path. Clean the tape path; see
"Cleaning Procedure" on page 4-3. Load a tape that is known
to
be
good and attempt the operation again, or run test 12 (with parameter A
set to 0) to verify the repair.

If this reference code continues to occur, run test 98 to check the read
channel gain values. If these values are not good, run test 99 to set
new values and run test 2 to verify the repair.
Action
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 (with parameter A set
to
0) after each FRU is
exchanged to verify the repair.
A cyclical redundancy check (CRC) error occurred during a write oper-
ation. This problem may be caused by a bad tape or a dirty tape path.
Clean the tape path; see "Cleaning Procedure" on page 4-3. Load a
tape that is known
to be
good and attempt the operation again, or run
test 12 (with parameter A set to 0) to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 (with parameter A set
to
0) after each FRU is
exchanged to verify the repair.

An auxiliary cyclical redundancy check (ACRC) error occurred during
a write operation. This problem may be caused by a bad tape or a
dirty tape path. Clean the tape path; see "Cleaning Procedure" on
page 4-3. Load a tape that is known to be good and attempt the oper-
ation again: or run test 12 (with parameter A set to 0) to verify the
repair.
If this reference code continues to occur, run test 98 to check the read
channel gain values. If these values are not good, run test 99 to set
new values and run test 2 to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 (with parameter A set
to
0) after each FRU is
exchanged to verify the repair.

An error that could not be recovered occurred during a write opera-
tion. This problem may be caused by a bad tape or a dirty tape path.
Clean the tape path; see "Cleaning Procedure" on page 4-3. Load a
tape that is known to be good and attempt the operation again, or run
test 2 to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 2 after each FRU is exchanged to verify the
repair.

The error detection circuits detected one track in error during a write
operation. This problem may be caused by a bad tape or a dirty tape
path. Clean the tape path; see "Cleaning Procedure" on page 4-3.
Load a tape that is known to be good and attempt the operation again,
or run test 12 (with parameter A set to 0) to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 (with parameter A set to 0) after each FRU is
exchanged to verify the repair.
