Handling Process
Step 1  Reinsert the SAS cable of the RAID card.
Step 2  Replace the RAID card.
Step 3  Replace the hard disk with the port, or check whether the hard disk is faulty on the SAS card interface.
Note: If the fault is rectified by any of the three steps, the other two steps are not required.
Root Cause
The link of the corresponding port is unstable, for example, the hard disk is faulty and the RAID card cable is loosely connected.
Suggestions
This type of faults is mainly caused by the fault of the hard disk with the port. The hard disk cannot be formatted during operating system installation.
