Configuring the RAID Manually

Configuring the RAID Manually

If the server supports the RAID function, configure the RAID for the server to improve system reliability. This section describes how to configure the RAID for Huawei 2288H V5 and RH5885H V3 servers. If you use servers of other models, see the product documentation of the server or consult the supplier about RAID configuration.

NOTE:

The RAID needs to be configured on each distributed server.

Configuring the RAID on the iBMC Web Page (Huawei 2288H V5 Servers)

Before installing the operating system, configure the RAID for the server to ensure storage performance and data security of the disks. This chapter describes how to configure the RAID on the iBMC web page for Huawei 2288H V5 servers.

Prerequisites

You have planned the RAID for the server based on eSight Server Installation Plan.

Procedure
  1. Log in to the iBMC web management page.

    1. Open Internet Explorer, enter https://IP address of the iBMC management port in the address box, and press Enter. The default IP address of the iBMC management port is 192.168.2.100.
    2. (Optional) If the security alarm window is displayed, click Continue to this website.
    3. Enter the user name and password, and click Log In.
      NOTE:

      The default user name is Administrator and the default password is Admin@9000.

  2. On the iBMC web management page, choose Information from the main menu.
  3. Power on the server.

    1. Choose Overview from the navigation pane on the left.
    2. If Power Status is displayed as , go to 5. Otherwise, go to 3.c.
    3. Click Power On.

      The system displays a message indicating that the operation is successful. The power status changes to .

  4. Choose System Info from the navigation pane on the left, and choose Storage tab on the right.
  5. Click the Configure tab and click the arrow icon next to Logical Drive to expand the options.

    Under Logical Drive, select Delete. If the logical disk configuration has been performed, select the Operation column of each row and click Save.

  6. Configure RAID 1 using Disk0 and Disk1.

    1. Under Logical Drive, select Create, set Write Policy to Write Back with BBU, set Init State to Quick Init, set Level to 1, and configure two physical disks.
      NOTE:

      If Write Back with BBU does not exist, set Write Policy to Write Back.

    2. Click Save.
    3. In the dialog box that is displayed, click Yes.

      If a message indicating that the operation succeeded is displayed, the RAID configuration is complete.

  7. Click Views to check whether the RAID level, write policy, and capacity are the same as planned. If they are consistent, the configuration is correct.

Configuring the RAID Manually (Huawei RH5885H V3 Server)

This section describes how to configure the RAID for Huawei RH5885H V3 server manually.

Prerequisites
  • The server has been connected to the keyboard, video, and mouse.

      Table 5-40 Parameters in the Virtual Drive Definition window

      Parameter

      Description

      How to Set

      RAID Level

      RAID level.

      Select a value from the drop-down list box.

      Strip Size

      Data strip size on each hard disk under the RAID configuration. The default value is 256 KB.

      Use the default value.

      Access Policy

      Data access policy. The options are as follows:

      • RW: Indicates that the data access is read-write. This option is selected by default.
      • Read Only: Indicates that the data access is read-only.
      • Blocked: Indicates that the data access is rejected.

      Use the default value.

      Read Policy

      Data read policy of a virtual disk. The options are as follows:

      • Normal: Disables the Read Ahead function.
      • Ahead: Enables the Read Ahead function. A controller reads-ahead sequential data or data to be used based on predictions and saves it to the cache. This function increases the read speed for sequential data access, but has little influence on the read speed for random data access.
      • Adaptive: When a virtual disk is set to the Adaptive Read Ahead mode, the controller enables the Read Ahead mode during two data access operations in successive sectors. The controller switches the mode to Normal (no-read-ahead) for random data access operations.

      Use the default value.

      Write Policy

      Data write policy of a virtual disk. The options are as follows:

      • Always Write Back: In this policy, the controller cache sends the host a signal indicating that data transmission is complete after receiving all transmitted data.
      • Write Through: In this policy, the controller cache sends the host a signal indicating that data transmission is complete after the subsystem of a virtual disk receives all transmitted data.
      • Write Back with BBU: If no battery backup unit (BBU) is configured or the configured BBU is faulty, the controller switches the mode to Write Through.

      Use the default value Write Back with BBU.

      IO Policy

      Policy for reading data in special virtual disks. The IO policy does not affect the read-ahead cache. The options are as follows:

      • Direct: Data is read directly and is not cached. This option is selected by default.
      • Cached: All read data is cached.

      Use the default value.

      Drive Cache

      Cache policy for special virtual disks.

      Use the default value.

      Disable BGI

      Indicates whether to disable the background initialization (BGI) function. The options are as follows:

      • No: Enables the BGI function. The system automatically initializes a new configuration that is used by the WebBIOS for configuring other items. This option is selected by default.
      • Yes: Disables the BIG function.

      Use the default value.

      Select Size

      Virtual disk space. When multiple virtual disks are created in a disk group, the specified space for virtual disks must be smaller than the total space of the disk group.

      Click Update Size or enter a value in the text box.

      NOTE:

      The Update Size button is frequently used in the following scenarios:

      • Only one virtual disk is created in a disk group.
      • Multiple virtual disks are created in a disk group and the virtual disk that is being created is the last one in the disk group.
    4. Set RAID Level to RAID 5 and click Update Size.

    5. Click Accept.

      The Confirm Page window is displayed, prompting you to confirm whether to set Write Policy to Write Back with BBU.

    6. Click Yes.

  11. Click Next.

    The Preview window is displayed.

  12. Click Accept.

    The Confirm Page window is displayed, prompting you to confirm whether to save the configuration.

  13. Click Yes.

    NOTE:

    If a RAID key for the CacheCade function is configured for the LSI SAS2208, the SSD caching configuration interface is displayed.

    The Manage SSD Caching window is displayed.

  14. If the Manage SSD Caching window is displayed, click Cancel.

    The Confirm Page window is displayed, prompting you to confirm whether to initialize the created RAID group. The initialization operation will delete all data in the created RAID group.

  15. Click Yes.

    The system starts initialization. When the initialization is complete, the Virtual Drives window is displayed.

  16. Click Home or Back.

  17. Configure the eighth hard disk as the global hot spare disk.

    1. In the Logical View window, click the eighth hard disk.

    2. In the window that is displayed, select Make Global HSP.

    3. Click Go.

    4. Click Back.

      The Logical View window is displayed.

  18. Click Exit.

    The Exit Confirmation dialog box is displayed.

  19. Click Yes.

    The Reset Page dialog box is displayed.

  20. Press Ctrl+Alt+Del to restart the server. If you log in to the server remotely through a maintenance network interface, click in the toolbar on the Remote Virtual Console page and choose Cold Reset. In the dialog box that is displayed, click Yes.
