    Parameter

    Description

    Array #00N

    Specifies the ID of the array.

    Array Size

    Specifies the capacity of the array.

    Array Status

    Specifies the status of the array. The value options are as follows:

    • Optimal: The virtual drive is running properly, and all member drives are in the Online state.
    • Degraded: The virtual drive is running abnormally, and a member drive is faulty or offline.
    • Failed: The virtual drive is faulty and cannot run properly.
    • Offline: The virtual drive is not enabled.

    Array Block Size

    Specifies the strip size of the array.

    Type

    Specifies the RAID level of the array.

    Array Members

    Specifies the list of member drives in the array.

Create Array

On the Create Array screen, you can create arrays.

Screen Introduction

On the Main Menu screen shown in Figure 10-153, select Create Array. The hard drive list is displayed, as shown in Figure 10-154.

Figure 10-154 Main Menu

Create a RAID array.

  1. On the screen shown in Figure 10-154, press Insert or the space key to add member hard drives to the Selected Drives area.
  2. Press Enter.

    The array configuration main screen is displayed, as shown in Figure 10-155. Table 10-28 describes the parameters displayed on the screen.

    Figure 10-155 Configuring the array

    Table 10-28 Parameter description

    Parameter

    Description

    Array Type

    Specifies the RAID level of the array.

    Array Label

    Specifies the array name.

    Array Size

    Specifies the capacity of an array.

    Stripe Size

    Specifies the stripe size (64 KB, 128 KB, 256 KB, 512 KB, and 1024 KB for option).

    If Array Type is set to RAID 1 or Volume, the parameter cannot be modified.

    Read Caching

    Enables or disables the cache read function.

    Write Caching

    Specifies the write caching policy. Values are as follows:

    • Enable Always: RAID cache is enabled in case of no capacitor protection, and data may be lost if a power failure occurs.
    • Enable With Backup Unit: RAID write cache is disabled when there is no capacitor protection or the capacitor is not in the Ready state. (recommended)
    • Disable: RAID cache write is disabled.

    Create RAID via

    Performs operations after an array is created.

    • For RAID 0, RAID 1, or Volume, the operations include Quick Init and Skip Init. Quick Init allows you to quickly initialize array data, and Skip Init allows you to recover the array and to set the RAID relationship among hard drives without clearing the data.
    • For an array with the redundancy function, in addition to Quick Init and Skip Init, the operations include Build/Verify and Clear, which allow you to initialize or clear array data.

  3. Configure array parameters based on Table 10-28.
  4. Select Done and press Enter.

    If hard drives added to the array are SSDs, a confirmation dialog box is displayed, indicating whether to disable Cache settings. Choose to enable or disable the function based on actual conditions.

    The system creates an array and performs the operations defined in Create RAID via.

    After the creation is complete, the system returns to the Main Menu screen.
