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.
- The “Periodic Drive Check Time” setting in the firmware application is set to
disabled (this is the default setting). This prevents automatic drive rebuild, which is not
recommended for live systems or troubleshooting.
To disable the Periodic Drive Check Time
1. From the Main Menu, choose view and edit Configuration parameters → Drive-side
SCSI Parameters → Periodic Drive Check Time.
A list of Periodic Drive Check Time intervals is displayed.
2. Select Disable.
A confirmation message is displayed.
3. Choose Yes to confirm.
Caution –
To prevent any possible data loss, back up user data to another storage
device prior to replacing a disk drive.
The following flowchart provides troubleshooting procedures for the FC drive LEDs.
