A Problem Occurs
You locate the Web application. It is running in a processor in processor enclosure 01.
The Web application’s TCP/IP connection is through an Ethernet adapter located in
slot 53 in I/O enclosure 31—that is, the first I/O enclosure attached to processor
enclosure 03.
At this point, you cannot tell whether the problem is an Internet issue outside the
company firewall, a hardware failure in system \2DIE4, or a problem with one of the
communications subsystems.
You check the event log for further clues and discover these multiple events:
•
A total of eight “path down” error messages: four generated by processors 0 and 1
in group 01, and four generated by processors 4 and 5 in group 03
•
Four “port error” messages from group 01: three from the PMF CRU in slot 55, and
one from the SEB in slot 52
