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.
  • 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.

Configuring a Global Hot Spare Drive

Prerequisites

Conditions

The following requirements must be met before you configure hot spare drives:

  • The server has idle hard drives, that is, hard drives in the Unconfigured Good state.
  • You have logged in to the server through a remote virtual console and can manage the server on a real-time basis.
  • You have accessed the main screen. For details, see Logging In to the Configuration Utility.

Data

Data preparation is not required for this operation.

Procedure

  1. In Logical View on the right of the main screen, select an idle hard drive to be configured as a hot spare drive, as shown in Figure 4-145.

    The idle hard drives are presented in blue text and are in the Unconfigured Good state.

    Figure 4-145 Selecting an idle hard drive

  2. Select Make Global hot spare on the physical drive property screen.

    Figure 4-146 Configuring a global hot spare drive

  3. Click Go.
  4. Click Home to go back to the main screen, as shown in Figure 4-147.

    In the Logical View area, the configured hot spare drive is displayed.

    The hot spare drive is presented in pink text under the Global Hot Spares node.

Configuring a Dedicated Hot Spare Drive

Prerequisites

Conditions

The following requirements must be met before you configure hot spare drives:

  • The server has idle hard drives, that is, hard drives in the Unconfigured Good state.
  • You have logged in to the server through a remote virtual console and can manage the server on a real-time basis.
  • You have accessed the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.

Data

Data preparation is not required for this operation.

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. In Logical View on the right of the Configuration Utility main screen, select an idle hard drive to be configured as a hot spare drive, as shown in Figure 4-148.

    The idle hard drives are presented in blue text and are in the Unconfigured Good state.

  2. Select Make Dedicated hot spare on the physical drive property screen.

    Figure 4-149 Configuring a dedicated hot spare drive

  3. Select a RAID array from Drive Groups.
  4. Click Go.
  5. Click Home to go back to the Configuration Utility main screen, as shown in Figure 4-150.

    In the Logical View area, the dedicated hot spare configured is displayed.

    The dedicated hot spare drive is presented in pink text under Dedicated Hot Spares.

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 left of the Configuration Utility main screen, select Physical View.

      The hard drives are listed.

      Figure 4-151 Hard drive list
    2. Select the hot spare drive to be deleted.

      The hot spare drive properties are displayed.

      Figure 4-152 Properties of a hot spare drive
    3. Select Remove HOTSPARE and click Go.

      The common hard drive property screen is displayed.
