Network Storage Agent can help in patch and firmware maintenance and to display a topology view of the entire SAN.

You can use Stortools to capture a snapshot of the system configuration, as well as to assist in component and system-wide testing and verification.

See TABLE 6-1for download URLs for StorTools and Network Storage Agent packages and documentation.

Common Problems

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.
