Sense data

When a drive encounters an error, it provides sense data as a response to the host.
Refer to the IBM TS4300 Tape Library SCSI Reference for library sense data information. Refer to the IBM
LTO Ultrium Tape Drive SCSI Reference for tape drive sense data information.
In addition, you can use the IBM Tape Diagnostic Tool (ITDT) to further examine data and determine
errors. See "IBM Tape Diagnostic tool (ITDT)" on page 83.

Drive Error Codes: Single-character display (SCD)

SCD drive error codes give descriptions of the errors and messages that pertain to the drive.
If you encounter problems while the tape drive is running, refer to "Finding event information" on page
77.
The SCD display appears on the inside back of an installed library and can be seen through the front
window of an expansion unit. It is seen on the lower center of a full-height drive. Each drive has a status
light and single-character display, that when visible provides drive informational and error conditions. The
single-character display shows either a single character, a dot (in the lower right of the display), or both.
Note: The SCD can be seen through the windows of expansion units, and for full-height drives only. If you
have a base unit without expansion units, or if you have half-height drives, the SCD cannot be seen.
"Single-character display (SCD) codes" on page 115 lists the codes for error conditions and informational
messages. If multiple errors occur, the code with the highest priority (represented by the lowest number)
displays first. When the error is corrected, the code with the next highest priority displays until no errors
remain.

e
35h Set when the tape system area
cannot be read successfully at
load time.
37h The operation failed because the
media cannot be loaded and
threaded.
38h The operation failed because the
media cannot be unloaded.
3Bh Set when the drive determines
that the data on tape is suspect
from a WORM point of view.
3Ch Set when the drive rejects a write
operation because the rules for
allowing WORM writes are not
met. Data can be appended only
to WORM media. Overwrites to
WORM media are not allowed.
Action Required
Copy the data to another tape
cartridge, and discard the old
cartridge.
Remove the tape and try
another. If the problem persists,
®
contact your IBM service
representative.
Ensure that tape drive firmware
is at the latest version. See
"Minimum firmware levels for
common library features" on
page iii.
®
Contact your IBM service
representative.
1. Copy the data to another
WORM tape cartridge.
2. Discard the faulty WORM
tape.
Write the data to a WORM tape
cartridge or write the data to a
non-WORM tape cartridge.
