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.
