CHAPTER 8MAINTENANCE AND SERVICING

8-1 INTRODUCTI ON

This chapter describes the maintenance and servicing information for the M2488 Tape drive. The fol-

lowing information is located in this chapter:

8-2 OPERATOR PANEL DISPLAYED ERROR MESSAGES

8-3 SENSE DATA

8-4 DIAGNOSTICS

8-5 FACTORY SETTINGS

8-6 ERROR RECOV ERY PROCEDURE S

8-7 MAINTENANCE TERMIN AL

8-8 PREVENTIVE MAINTEN ANCE

8-11 REMOVE AND REPLACE P ROCEDURES

8-10 MANUAL TAPE REMOVAL PRO CEDURE

8-2 OPERATOR PANEL DISPLAYED ERROR MESSAGES

When specific error types are detected by the tape subsystem, messages are displayed on the operator

panel display. This section describes the various error types that may be displayed and the appropriate

operator and system action required when the error is displayed. Detailed information describing the

error codes is in Appendix F.

8-2.1 OZONE:xxxxyyyy <text>

Ozone messages signal the operator that a non-recoverable microcode error has just occurred. The

microcode controlling the tape unit operation has detected a condition that should “never” occur or a

condition that may compromise data integrity. The tape unit has performed an internal reset and

returns to a known state. All buffered data is discarded and tape motion is halted. Power On and Not

Ready to Ready Unit Attention check conditions are returned to the SCSI host.

Ozone messages may be caused by the following:

• Incorrect and complicated SCSI operation/sequences by

1) Host adaptor under abnormal conditions

2) incorrect conditions of SCSI termination or cables.

• Abnormal system configuration such as a duplicated SCSI ID Setting, etc.

• During an error recovery operation for excessively damaged tape medias.

• Broken hardware in a complicated manner.

xxxxyyyy specify a unique error condition that the microcode has detected. <text> gives a short

description of the condition that caused the Ozone. These error codes and text descriptions hold little

information for anyone except the firmware developers.

When an Ozone message is displayed, the current job at the host computer should be aborted as data

integrity is compromised. Data being written to tape is no longer valid. Read data on tape is not

affected on the media.
