General Tips For Troubleshooting

In all cases:

Verify that all patches and firmware are the most recent ones available. See
“Minimum Software Component Versions and Patches” on page 36.

Verify all ports are logged in with solid green light on the switch port.

Check the array and switch cables and power cord for secure attachment.

Re-seat the cables if necessary.

Become familiar with

luxadm

and

cfgadm

outputs while the system is in a

known good state. Check the outputs during a problem.

Configure Network Storage Agent to monitor SAN devices and email
Administrator if a problem occurs.

Monitor the SANsurfer GUI for error counters. Large number of errors in a short
time can indicate a problem link. Network Storage Agent also monitors error
counters.
