5 Diagnosing and Rectifying Faults
Quick Recovery Method
1. If a RAID controller card
firmware error exists,
replace the RAID controller
card or supercapacitor. Then
check whether the fault is
rectified.
● If yes, no further action is
required.
● If no, go to 2.
2. Check whether the drives,
drive backplane, and SAS
cables are faulty.
● If yes, replace faulty
components.
● If no, go to 3.
3. If the RAID array is offline,
import it again. Then check
whether the fault is
rectified.
● If yes, no further action is
required.
● If no, go to 4.
4. If the supercapacitor runs
out of power, follow the
instructions shown in the
displayed messages to keep
the server running. After the
server runs for 30 minutes,
check the supercapacitor
status. If the supercapacitor
is abnormal, replace it.
Follow the handling procedure.
