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 1

Creating RAID 1

Scenarios

  • 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. If the hard disk data needs to be retained, back up the data first.
  • The LSI SAS3008IR supports SAS/SATA HDDs and SSDs. Hard drives in one RAID array must be of the same type, but can have different capacities or be provided by different vendors.
  • RAID 0, 1, 10, and 1E lists the number of hard drives required by each RAID level.

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. Create RAID 1.

    1. On the Adapter Properties screen, select RAID Properties and press Enter.

      The Select New Volume Type screen is displayed, as shown in Figure 6-14.

      Figure 6-14 Select New Volume Type screen
    2. Select Create RAID 1 Volume and press Enter.

      The Create New Volume screen is displayed, as shown in Figure 6-15. Table 6-7 describes the parameters on the screen.

      Table 6-7 Parameters

      Parameter

      Description

      Volume Type

      RAID level.

      Volume Size

      RAID array capacity.

      Slot Num

      Slot number of a hard drive.

      Device Identifier

      Hard drive name.

      RAID Disk

      Indicates whether the hard drive is a member of the RAID array.

      • Yes: The hard drive is a member of the RAID array.
      • No: The hard drive is not a member of the RAID array.

      Drive Status

      Hard drive status.

      If the status displays Inc RAID, it indicates that the hard drive does not support the SMART or SATA expansion command. You are advised to replace the hard drive or link.

      Pred Fail

      Indicates whether the hard drive is to be identified as failed by the controller card.

      • Yes: The hard drive is to be identified as failed by the RAID controller card and you need to replace it.
      • No: The hard drive is working properly.

      Disk Size

      Hard drive capacity.

    3. Add hard drives to the RAID array.

      Press the space bar to specify whether to add a hard drive to the RAID array, as shown in Figure 6-16.

      In the RAID Disk column:

      • Yes indicates that the hard drive will be added to the RAID array.
      • No indicates that the hard drive will not be added to the RAID array.
      • A RAID 1 array supports two hard drives.
      • If the total number of hard drives in all RAID arrays under a RAID controller card exceeds 14, no hard drive can be added to RAID arrays.
      • The first added hard drive is the primary drive, and the other added hard drives are secondary drives. The secondary drives synchronize data from the primary drive.
      • To facilitate identification of the positions of primary and secondary drives in future maintenance, add the hard drives in ascending order of slot numbers.
      Figure 6-16 Adding hard drives
    4. Press C.

      The RAID array creation confirmation screen is displayed.

    5. Select Save changes then exit this menu and press Enter.

      RAID array creation takes about 1 minute, during which the Configuration Utility is in the suspended state. Do not perform any other operations during this period.

      After the configuration is complete, the Figure 6-10 screen is displayed.

After the RAID 1 array is created, the LSI SAS3008IR automatically starts a background initialization. The background initialization synchronizes data from the primary drive to the secondary drive. It does not affect the use of the RAID array but affects the performance.

Additional Information

Related Tasks

After creating the RAID array, check the configuration result as follows:

  1. On the Adapter Properties screen, select RAID Properties and press Enter.

    The Select New Volume Type screen is displayed.

  2. Select View Existing Volume and press Enter.

    RAID information is displayed.
