Table 10-27 RAID property parametersParameter
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

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.
Create a RAID array.
- On the screen shown in Figure 10-154, press Insert or the space key to add member hard drives to the Selected Drives area.
- 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.
Table 10-28 Parameter descriptionParameter
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.
- Configure array parameters based on Table 10-28.
- 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.
Initialize Drives
On the Initialize Drives screen, you can initialize hard drives.
Before creating a RAID array, you must initialize member hard drives.
Screen Introduction
On the Main Menu screen shown in Figure 10-153, select Initialize Drives. The hard drive selection screen is displayed, as shown in Figure 10-156.
Procedure
- In the Select drives for initialization area, press the space key or Insert to select the hard drives to be initialized.
The selected hard drives are displayed in the Select Drives area, as shown in Figure 10-157.
To deselect hard drives, press Del.
- Press Enter.
A confirmation dialog box is displayed.
![]()
Initialization clears all the data on hard drives. Exercise cautious to perform the operation.
- Enter Y.
The initialization starts, which takes approximately 10s.
- Press any key to return to Main Menu.
Secure Erase
On the Secure Erase screen, you can erase all information from hard drives.
This operation will delete all data from the hard drive. Before performing the operation, check whether the data needs to be backed up.

- Press any key to return to Main Menu.
Uninitialize Drives
On the Uninitialize Drives screen, you can initialize hard drives to change them into pass-through hard drives.
This operation will delete all data from the hard drive. Before performing the operation, check whether the data needs to be backed up.
