(6321) Reference codes

An optical storage unit failure occurred.

Notes:
  1. If the system is available, use online diagnostic tests when possible.
  2. Use the Hardware Service Manager (HSM) verify function (via DST or SST) and verify that the unit is operating correctly.
  3. Search the problem log (WRKPRB) for a recent optical storage entry that might assist in analyzing the problem. The WRKPRB entry will provide a reference code that can be found in the following table.
If the system is available, attempt the failing operation again with an optical media that is known to be good. Does the operation complete successfully?
  • Yes: The original optical media may be defective, or the problem may be intermittent. Attempt the failing operation again with the original optical media to verify. This ends the procedure.
  • No: Look at the 8 rightmost characters of the Data display for word 1. These 8 characters are the reference code. Find the reference code in the following table.
