Appendix E. Message Retrieval at the Host
How error information is obtained from the host depends on the type of device driver
being utilized. Table E-1 provides instructions specific to your type of device driver.
Obtaining Error Information From an IBM™ System p
IBM device drivers for the System p operating system logs error information when an
error occurs on a tape drive or library.
The error information includes the following:
• Device VPD
• SCSI command parameters
• SCSI sense data (if available)
The AIX
®
Tape and Media Changer Device Driver for System p provides logging to
the system error log for a variety of errors. You can view the error log by following
this procedure.
1.
At the AIX command line, type
errpt |pg
to display a summary report, or type
errpt -a |pg
to display a detailed report. Press [
Enter
].
Note:
In most cases you will use the summary report to find the date and time of any
errors related to library devices, then use the detail report to obtain the sense
data needed to identify the cause of the error.
2.
Press [
Enter
] to scroll through the error log.
3. Type q and press [ Enter ], to quit the error log at any time.
