Issue 12 (2022-08-30)
Diagnosis Procedure
1. Check whether the target drive is compatible by using
Computing Product Compatibility
2. Check whether the cable connection between the RAID
controller card and the drive backplane is correct. For
details, see the internal cabling section in the maintenance
and service guide of the corresponding server.
3. Ensure that the target drive is identified by the RAID
controller, and check the BIOS to see whether the target
storage devices, including SATADOMs, SD cards, and built-
in USB flash drives, are identified.
4. Check the model of the RAID controller card and
determine whether to configure a RAID array. For details,
see the user guide of the RAID controller card.
5. Check the RAID array properties to ensure that the boot
drive and the target drive are the same or in the same
RAID array.
6. Check whether the drive is a 4K drive.
7. Check whether the loaded RAID controller card driver is
correct.
8. Format the drive or reconfigure the RAID array.

information contains crashed
process names or board
vendor names. For example,
FC_XX indicates an FC device
breakdown.
Check whether it is a PCIe
card compatibility issue:
● Check the power supply.
● Check whether the PCIe
protocol is supported by
the PCIe card.
● Check the drivers.
