Troubleshooting This chapter describes common problems and probable causes, known issues, and provides general troubleshooting advice. To begin troubleshooting deployment problems, review the list of Known Issues below first to see if any issues match the environment and symptoms. If none of the known issues apply, see "Common " for issue diagnosis. For general troubleshooting advice, see "Basic troubleshooting techniques." Known issues The following is a list of known issues associated with Solaris deployment and ProLiant servers.

Express slots 1, 2, 4, 5, 7, or 8 on a DL580 G5 server.
•
OS releases affected—Solaris 10 8/07, 5/08
•
Hardware affected—HP ProLiant DL580 G5
•
Description—Solaris may stop responding, or will not respond properly during deployment if a
PCI-Express Controller, such as a Smart Array P800 is installed in slots 1, 2, 4, 5, 7, or 8.
