Diagnosing Port Connections; Using System Logs; Using Alom Event Logs - Sun Microsystems IB Switch 9P Administration Manual

Diagnosing Port Connections

If a port does not work, check the following:
Ensure that the cable connections are secure and the cables are connected to the
■
correct ports at both ends of the link.
Ensure that the LED lights are green. (If LED lights are amber, a fault has
■
occurred and the port requires attention.)

Using System Logs

The Sun IB switch logs information about important system events to both internal
non-volatile event logs and Solaris host-based system logs (using syslog
mechanism). The internal non-volatile event log is used only by ALOM. You can
view its contents by using the ALOM showlogs command.
The Solaris host based system log is used by both InfiniBand management software
and ALOM. System logs can be accessed through usual Solaris syslog means.

Using ALOM Event Logs

The contents of the switch's non-volatile event log can be seen using the ALOM
showlogs command.
If a fault occurs, ensure that the problem you encountered is actually caused by the
switch. If the problem appears to be caused by the switch, then follow these next
steps.
1. Use the showlogs command with the appropriate option.
