Monitoring the System Activity
The LEDs on the bezel of Tiger Box allow you to monitor the system activity. You can
monitor the system activity without removing the front panel bezel:
Monitoring RAID Drives Activity
Note:
To monitor RAID drives activity, you should remove the front panel bezel.
You can monitor the activity of the RAID drives using the LED indicators on the top
of each HDD carrier:
Important:
To diagnose RAID drive failure, it is advisable to regularly check
the RAID status in the Storage page of Tiger Store’s web UI (refer to the Tiger
Store Administration Guide). Degraded RAID status indicates that a drive has
failed and needs to be replaced with the spare drive, following the steps described in
“Replacing a Failed Drive” on page 21.
