How error information is obtained from the host depends on the type of device driver that is used.
Table 42 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.
v Device VPD
v SCSI command parameters
v SCSI sense data (if available)
The AIX Tape and Media Changer Device Driver for 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: 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 = 3572-TL]), see
"SCSI sense data definition" on page 218 and the SCSI sense data in "Library sense data" on page 208.
v For drive errors [Resource Name = rmtn (for example, rmt0) and Resource Type = LTO], see "SCSI
sense data definition" on page 218 and locate the SCSI sense data in "Tape drive sense data" on page
209.
