5 Diagnosing and Rectifying Faults
Quick Recovery Method
1. If a RAID controller card
firmware error exists,
replace the RAID controller
card, supercapacitor, or BBU.
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 BBU or 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 BBU or
supercapacitor status. If the
BBU or supercapacitor is
abnormal, replace it.
Follow the handling procedure.
