For overview information about drive LEDs and how they work, see “Front-Panel LEDs” on page 6-2.

You can check physical drive parameters using the firmware application. From the firmware Main Menu, choose view and edit scsi drives. For more information about the firmware application, refer to the SANnet II Family RAID Firmware User’s Guide.

Caution – When you rotate or replace drives, make sure that:

-All I/O is stopped.

A list of Periodic Drive Check Time intervals is displayed.
