Appendix E. Message retrieval at the host

Retrieving messages from different hosts are discussed in this appendix.
Obtaining error information from the host
How error information is obtained from the host depends on the type of device driver being utilized.
Refer to the table for instructions specific to your type of device driver.
If you are...

Retrieving from an IBM System p or IBM Power

IBM device drivers for the System p system logs error information when an error occurs on a tape drive
or library.
The error information includes:
1. Device VPD
2. SCSI command parameters
3. SCSI sense data (if available)
The AIX Tape and Media Changer Device Driver for the System p provides logging to the system error
log for various 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, use the summary report to find the date and time of any errors that are related
to library devices, then use the detail report to obtain the sense data that is 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.
To correct a problem you noticed in the errpt report, determine the type of error by using the examples
that follow:
v For library errors [Resource Name = smcn (for example, smc0) and Resource Type = 3573-TL]), refer to
"SCSI sense data definition" on page 314 and Sense Data in Appendix C.
v For drive errors [Resource Name = rmtn (for example, rmt0) and Resource Type = LTO], refer to "SCSI
sense data definition" on page 314 and Sense Data in Appendix C.
v For Fibre Channel errors (not Fibre Channel adapter errors), determine which host adapter and device
are affected, and go to that host documentation to resolve any Fibre Channel problems. If unsuccessful,
call for IBM support.
