Managing Hot Spare Drives

Managing Hot Spare Drives

After RAID configuration of the hard drives of a server, configuration of hot spare drives increases security and reduces impact on services from hard drive faults.

The controller card supports two types of hot spare drives:

  • Global hot spare drive: shared by all RAID arrays of a controller, which can be configured with one or more global hot spare drives. A global hot spare drive automatically replaces a failed hard drive of the same type as the hot spare drive in any RAID array.
  • Dedicated hot spare drive: replaces a failed hard drive of the same type as the hot spare drive only in a specified RAID array, which can be configured with one or more dedicated hot spare drives.
    • The HDDs and SSDs cannot be used as the hot spare drives of each other.
    • The HDDs include SAS HDDs and SATA HDDS. If the member drives of a RAID array are SAS drives, the SATA drives can be used as dedicated hot spare drives. If the member drives are SATA drives, the SAS drives cannot be used as dedicated hot spare drives.
    • An idle hard drive can be configured as a hot spare drive, but a RAID member drive cannot be configured as a hot spare drive.
    • A hot spare drive must be a SATA or SAS drive, and it must have at least the capacity of the RAID member drive with the largest capacity.
    • All RAID levels except RAID 0 support hot spare drives.
    • You cannot directly change a global hot spare drive to a dedicated hot spare drive or vice versa. You need to set the hard drive to idle state, and then set it as s global or dedicated hot spare drive as required.

Configuring a Global Hot Spare Drive

Procedure

  1. Access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.
  2. Access the Drive Management screen.

    1. On the main screen, select Main Menu and press Enter.
    2. Select Drive Management, and press Enter.
    3. Select a drive and press Enter. The drive detail screen is displayed.

  3. Set the drive as a global hot spare drive.

    1. Set Operation to Assign Global Hot Spare Drive.
    2. Select Go and press Enter.

      A confirmation screen is displayed.

    3. Set Confirm to Enable.
    4. Select Yes and press Enter.

      The message "The operation has been performed successfully" is displayed.

    5. Press Enter to finish the configuration and return to the previous screen.

Configuring a Dedicated Hot Spare Drive

Procedure

If SAS drives are grouped as a RAID array, a SATA drive can be used as a dedicated hot spare drive. If SATA drives are grouped as a RAID array, the SAS drive cannot be used as the dedicated hot spare drive.

  1. Access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.
  2. Access the Drive Management screen.

    1. On the main screen, select Main Menu and press Enter.
    2. Select Drive Management, and press Enter.
    3. Select a drive and press Enter. The drive detail screen is displayed.

  3. Set a drive as a dedicated hot spare drive.

    1. Set Operation to Assign Dedicated Hot Spare Drive.
    2. Select Go and press Enter.

      The virtual drive list is displayed.

    3. Select the virtual drive to be associated and press Enter.
    4. Select Enabled and press Enter.
    5. Select OK and press Enter.

      A confirmation screen is displayed.

    8. Press Enter to finish the configuration and return to the previous screen.

Deleting a Hot Spare Drive

Scenarios

If the number of existing hard drives in the current environment is insufficient, you can delete an existing hot spare drive so that it restores to a common hard drive.

Procedure
