Huawei V2 and V3 Server RAID Controller Card User Guide 36

This document describes the appearances and features of the redundant array of independent disks (RAID) controller cards, how to configure properties for the RAID controller cards, and how to install drivers. The RAID controller cards include the LSI SAS2208, LSI SAS2308, LSI SAS3008, LSI SAS3108, LSI SoftRAID, PM8060, and PM8068.

Hard Drive Fault

Hard Drive Fault


A hard drive fault occurs if any of the following symptoms occurs on a server:

  • The hard drive fault indicator is on.
  • The hard drive activity indicator is off.
  • A hard drive fault alarm was generated.


  • Before removing a hard drive, determine its location to prevent misoperations. If another hard drive is removed, the RAID array will fail.
  • After a failed hard drive is disconnected from the hard drive backplane, wait for 30 seconds before removing it and inserting a new one. The alarm persists after a new hard drive is installed and will be cleared after the RAID array is rebuilt. Do not frequently hot-swap a hard drive to prevent new alarms.
  1. Remove the faulty hard drive.
  2. Determine whether data can be restored.

    • For RAID 0, data cannot be restored. Install a new hard drive and reconfigure the RAID array. No further action is required.
    • If the RAID array has a hot spare drive, the hot spare drive automatically replaces the failed hard drive and rebuilds data.
    • If the RAID array is redundant but does not have a hot spare drive, install a new hard drive.

  3. Install a new hard drive.

    • If the new hard drive does not contain data, it works as follows:
      • If the RAID array has a hot spare drive, data of the hot spare drive will be automatically copied to the newly inserted hard drive. Then, the original hot spare drive is still the hot spare drive. No further action is required.
      • If the original RAID array is redundant but does not have a hot spare drive, data is automatically rebuilt to the new hard drive. No further action is required.
    • If the new hard drive already contains RAID information, go to Step 4.

  4. Safely erase data from the inserted hard drive.
  5. Manually rebuild a RAID array.
