Issue Description

Configuration: a Huawei Tecal RH2288H V3 server+ an LSISAS3108 RAID controller card + 6 x 2 TB SATA hard disk + 2 x 300 GB SAS hard disk

 

RAID configuration: Five 2 TB SATA hard disks are configured for a RAID 5, one 2 TB SATA hard disk is configured as a dedicated hot spare disk, and two 300 GB SAS hard disks are configured for RAID 1.

 

The hard disk in slot0 is in the unconfig bad (UB) state. The hot spare disk in slot5 is added to RAID 5 and the RAID 5 rebuild is complete. After the hard disk in slot0 is replaced, fail to import the configuration of the hard disk in slot0 back to RAID 5.

Solution

1.    In the RAID configuration window, set slot0 to foreign and then clear the foreign configuration. For details, see "Importing or Clearing a Foreign Configuration" in Huawei V2 and V3 Server RAID Controller Card User Guide and Huawei V5 Server RAID Controller Card User Guide.

1.       On the VD Mgmt page, select slot5 (the hot spare disk) and select Copyback to copy the data back to the target disk in slot0.

Conclusion

The hot spare disk is added to RAID5 and the RAID5 rebuild is complete. Remove and insert the hard disk back to slot0, but the hard disk cannot be added to the RAID group.

Solution

Because the hard disk cannot be removed and inserted back again, you are advised to clear the RAID configuration of the faulty hard disk in slot0 and copy data back from slot5 to slot0 remotely. If you can remove the faulty hard disk from the slot, manually remove the hard disk and insert back. The RAID controller card supports automatic configuration copyback.
