Release Date

Keyword

LSI SAS3108, RAID 1, hard disk insertion and removal, recovery procedure

Symptom

A RAID 1 array of two hard disks is managed by the LSI SAS3108 RAID controller card. After one of the hard disks is removed and then inserted back, the system reports an alarm indicating failure of the disk.

Key Process and Cause Analysis

After a hard disk in the RAID 1 array is removed, the RAID 1 array is degraded. When the hard disk is inserted back, the RAID controller card identifies the hard disk as a faulty disk. You need to manually rebuild the RAID array.

Conclusion and Solution

Method 1: Restart the server, and rebuild the RAID 1 array on the BIOS screen of the RAID controller card.

  1. Restart the server, and access the BIOS screen of the RAID controller card.

  2. On the drive management screen, choose the hard disk whose status is Unconfigured Bad. Choose Operation > Make Unconfigured Good.

  3. Choose Configuration Management > Manage Foreign Configuration > Preview Foreign Configuration > Import Foreign Configuration > Yes.

  4. Access the drive management screen. The rebuild on the faulty hard disk is started.

    The system event logs show that the faulty disk alarm is cleared, and RAID rebuild is started.

  5. Access the virtual drive management screen to view the RAID status. If the status is changed from Degraded to Optimal, the RAID 1 array rebuild is complete.

    The system logs show that the RAID 1 array rebuild is complete.

Method 2: Rebuild the RAID 1 array on the OS.

  1. Visit https://docs.broadcom.com/docs/1.21.06_StorCLI to download the RAID controller card tool. Decompress the downloaded package, and copy the rpm package from the Linux folder to the OS. Run the rpm command to install the tool. After the installation is complete, the tool is saved in the /opt/MegaRAID/storcli folder.

  2. In the /opt/MegaRAID/storcli folder, run the ./storcli64 /c0 /show command to check the status of the RAID 1 array. The status of the RAID 1 array is Dgrd, and the status of a hard disk is UBad.

  3. Run the ./storcli64 /c0/eX/sX set good command to set the status of the unconfigured bad hard disk to unconfigured good. (The value of X in the command is determined according to the on-site situation. In this case, the EID:Slt value of the faulty hard disk is 8:0. Therefore, eX is e8, and sX is s0.)

  4. Run the ./storcli64 /c0 show command to check whether status of the hard disk is UGood.

  5. Run the ./storcli64 /c0/fall import preview command to check the number of foreign disks.

  6. Run the ./storcli64 /c0/fall import command to import the foreign RAID configuration.

  7. After the import, the RAID rebuild on the faulty disk starts. Run the ./storcli64 /c0/eX/sX show rebuild command to view the rebuild progress and estimated remaining time.

  8. After the rebuild is complete, run the ./storcli64 /c0 show command to check the status of the RAID 1 array. If the status is changed from Dgrd to Optl, the RAID 1 array rebuild is complete.
