5 – Status LED Indications
System Powered, No Drive Activity
When the Fusion QR is powered on, and no data is being
written to or read from the drives, the Power and Drive LEDs
stay on
(Figure 10).
Drive Activity
When data is being read from or written to a drive, its
corresponding LED will flash
(Figure 11).
Drive Not Recognized
When a drive LED stays off while the others remain lit, the
corresponding drive(s) is not recognized
(Figure 12). There
are a few possible causes for a drive to not be recognized,
including: the corresponding drive module is not plugged
securely into the enclosure or the drive itself has failed. If
reseating the drive does not fix the situation, replace the
drive as soon as possible.
RAID 5 or RAID 10 Rebuild
After inserting a drive into the QR enclosure to replace a failed
drive from a RAID 5 or RAID 10 group, the corresponding
LED alternately flashes orange and green until the RAID
volume has been rebuilt
(Figure 13). Once the rebuild is
complete, the LED returns to normal operation.
Bad Drive Detected
When the QR determines a drive has gone bad, the
corresponding LED lights red continuously
(Figure 14).
Causes for this condition include the drive’s failure to spin
up, too many physical errors on the drive, drive BIOS failure,
etc. Replace the drive as soon as possible.
