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.

Creating RAID 0

Creating RAID 0

Scenarios

For details about the number of hard drives supported by different RAID levels, see Table 9-2.

The LSI SoftRAID BIOS allows you to create a RAID array using any of the following methods:

  • Easy Configuration: This is a fast creation mode. In this mode, the existing RAID configuration data on hard drives is not deleted during RAID creation, but the RAID storage capacity cannot be configured.
  • New Configuration: This is a common creation mode. In this mode, the existing RAID configuration data on hard drives is deleted during RAID creation, and the RAID storage capacity can be configured.
  • View/Add Configuration: This creation mode does not affect the existing RAID configuration data, and the RAID storage capacity can be configured.

The procedures and screens of the three modes are similar. This section describes only the New Configuration mode as an example.

  • The LSI SoftRAID supports SATA HDDs and SATA SSDs. Hard drives in one RAID array must be of the same type, but can have different capacities or be provided by different vendors.
  • Data on a hard drive will be deleted after the hard drive is added to a RAID array. Before creating a RAID array, check that there is no data on hard drives or the data on hard drives is not required.

Procedure

  1. Back up data on hard drives and access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.
  2. On the Configuration Utility main screen, choose Configure > New Configuration.

    A confirmation dialog box is displayed, as shown in Figure 9-5.

    Figure 9-5 Proceeding to RAID array creation

  3. Use and to select Yes and press Enter.

    The hard drive list is displayed, as shown in Figure 9-6.

    Figure 9-6 Hard drive list

  4. Use and to select hard drives to be added to the RAID array and press the space bar to change the drive status from READY to ONLINE, as shown in Figure 9-7.

    You can select an idle hard drive and press F4 to configure the hard drive as a hot spare drive.

  5. Press Enter.

    The drive array selection screen is displayed, as shown in Figure 9-8.

  7. Press F10 to save the configuration.

    The RAID array properties are displayed, as shown in Figure 9-10.

    Parameter

    Operation and Description

    RAID

    Select RAID and press Enter to display the available RAID levels.

    For details about the number of hard drives supported by different RAID levels, see Table 9-2.

    Units

    Select Units and press Enter to set the storage capacity unit. The unit can be MB, GB, or TB.

    Size

    Select Size and press Enter to set the RAID storage capacity.

    NOTE:

    The size of a RAID 10 array is automatically generated and cannot be configured.

    DWC (Disk Write Cache)

    Indicates whether drive write caching is enabled for member drives. It is disabled by default.

    Select DWC and press Enter to set this parameter.

    RA (Read Ahead)

    Indicates whether the Read Ahead (RA) mode is enabled. It is enabled by default.

    Select RA and press Enter to set this parameter.

    SPAN

    Indicates whether spans are included. This parameter is valid only for RAID 10.

  9. Select RAID 0 and press Enter.
  10. Set other properties of the virtual drive by referring to Table 9-4
  11. After the configuration, select Accept and press Enter.

    The screen shown in Figure 9-7 is displayed.

  12. Press Enter to complete the configuration.

    A confirmation dialog box is displayed, as shown in Figure 9-11.

    The Virtual Drive(s) Configured pane displays the RAID configuration. Determine whether to save the configuration based on the displayed information.

    Figure 9-11 Confirming the configuration

  13. Select Yes and press Enter.
  14. Press Esc to return to the Configuration Utility main screen.
  15. Initialize the created RAID array.

    1. On the Configuration Utility main screen, choose Initialize and press Enter.

      The virtual drive list is displayed, as shown in Figure 9-12.

    2. Press the space bar to select the virtual drive to be initialized and press F10.

      A confirmation dialog box is displayed.

    3. Select Yes and press Enter to start initialization.

      When the initialization is complete, "100% Completed" is displayed, as shown in Figure 9-13.

    4. Press Esc to exit the initialization progress screen.
    5. Press Esc to exit the virtual drive selection screen.

      The Configuration Utility main screen is displayed.
