Responding to Error Messages and Check
Codes
Error messages and check codes can appear in the following formats:
•
CHK XX, where XX represents a hexadecimal error code
For example, CHK 98
•
XXXXXXXX, which can represent any characters or a hexadecimal code
For example, CTRL ERR FRU = E024
These error messages and check codes indicate a hardware or software problem that
might require CRU replacement. If you receive an error message or check code, take
the following steps:
1. Write down the complete message. To view the complete message, press and
hold down the TEST button to scroll the message from right to left across the
message panel.
2. Press the RESET button twice to clear the message.
3. Retry the operation (usually by pressing the START button).
4. If the message persists, stop all applications using the tape drive, bring down the
drive, and cycle power to the drive.
5. If cycling power to the drive does not clear the message, use TMDS diagnostics
(for NonStop Himalaya K-series servers) or use SCF commands (for NonStop
Himalaya S-series servers) to isolate the problem in the tape drive CRU or its
controller.
6. If you believe the drive has a malfunction, remove the tape drive CRU from the
tape drive module (see Replacing a 5190 or 5194 Tape Drive CRU on page 6-5). If
you believe the 3216 controller logic board or BIC has a malfunction, replace it and
contact your service provider for instructions about shipping the malfunctioning
hardware back to Compaq. Be sure to include a description of the problem, the
operations that preceded the problem, and any messages you observed.
