Software and Microcode Errors
Some failures might be caused by software errors or by microcode errors. If you think
you have a software or microcode error:
1. Ensure that your system software, adapter microcode, disk drive microcode, and
enclosure microcode are all at the latest levels. Information about the latest levels of
software and microcode is given on the web support page (see “Web Support Page”
on page 131).
2. Make a note of all failure indicators: for example, the contents of error logs, or
physical symptoms.
3. For AIX Versions 4.2 and above, run the snap -g command to collect system
configuration data, and to dump data.
For AIX versions below 4.2, go to the using-system service aids and select Display
Vital Product Data to display the VPD of the failing system. Make a note of the
VPD for all the SCSI adapters and disk drives.
4. Report the problem to your support center. The center can tell you whether you
have a known problem, and can, if necessary, provide you with a correction for the
software or microcode.
Diagnostics Information
Note: If you were sent here from other instructions, return to those instructions when
you have finished running the diagnostics.
Concurrent Diagnostics
When the instructions tell you to run concurrent diagnostics, run diagnostics (not
Advanced Diagnostics) in System Verification mode (see the using-system Installation
and Service Guide).
Nonconcurrent Diagnostics
When the instructions tell you to run nonconcurrent diagnostics, run Advanced
Diagnostics in System Verification mode (see the using-system Installation and Service
Guide).
Problems Corrected
Run Advanced Diagnostics in System Verification mode only to the device that you
have just repaired. You can then enter information to prevent the generation of another
SRN for the problem that you have just solved. If you do not enter that information, the
errors that were previously logged for your problem might generate another SRN.
