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.

Managing Spare Drives

Managing 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. Configure a global hot spare drive.

    1. Press Ctrl+N to switch to the PD Mgmt tab.
    2. Select the hard drive to be configured.
    3. Press F2 and choose Make Global HS from the shortcut menu.

    4. Press Enter.

      The hot spare drive status changes to Hotspare.

  3. Check the configuration result.

    1. Press Ctrl+P to switch to the VD Mgmt tab.
    2. On the VD Mgmt tab, view details about the global hot spare drive, as shown in Figure 8-55.

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. Configure a dedicated hot spare drive.

    1. On the VD Mgmt tab, select a RAID.
    2. Press F2 and choose Make Ded. HS from the shortcut menu, as shown in Figure 8-56.
      Figure 8-56 Configuring a dedicated hot spare drive
    3. Press Enter.

      The screen for configuring the dedicated hot spare drive is displayed.

    4. Select a hot spare drive and press Enter.

      [X] is displayed on the left of the selected hot spare drive, as shown in Figure 8-57.

  3. Check the configuration result.

    On the VD Mgmt tab, view details about the dedicated hot spare drive, as shown in Figure 8-58.

Deleting a Hot Spare Drive

Scenarios

If the number of member hard drives in a RAID array is insufficient, you can delete a hot spare drive to enable it to function as a common hard drive.

Procedure

  1. Access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.
  2. Delete a hot spare drive.

    1. On the PD Mgmt tab, choose the hot spare drive to be deleted.
    2. Press F2 and choose Remove Hot Spare drive from the shortcut menu, as shown in Figure 8-59.
      Figure 8-59 Deleting a hot spare drive
    3. Press Enter.

      The drive status changes to UG as shown in Figure 8-60.
