Hi,

If you like to configure the unit with RAID6 then you have to delete the existing array and have to create a new array, once the array is created with RAID6 the unit will start the synchronization process. The synchronization process will take 12 hours to complete. Kindly make sure that the system doesn't go to sleep during the process.

Note: Please make sure to backup your data (if you have any) before deleting and recreating the Disk Array and Logical Drive.

Follow the below steps to delete Disk Array.

To delete a disk array:

1. Open Promise utility and click the padlock on the left bottom corner to unlock the utility.

Once the Utility is unlocked, do one of the following actions:

• From the Dashboard window, click the Disk Array link.
• From the Storage menu, choose Disk Array.

2. Mouse-over the disk array you want then click the Delete button.

3. In the Confirmation box, type the word “confirm” in the field provided and click the Confirm
button.

Note: Deleting the array will delete the logical drive as well. If you have any data on the unit, it will be deleted, so please back up all your data before deleting the array.

To create a disk array:

1. From the Dashboard menu, click the Disk Array link.

2. Click the Create Disk Array button.

3. Accept the defaults or make changes:

• Enter an alias in the Alias field
Maximum of 32 characters; letters, numbers, space between characters, and underline.
• Enable Media Patrol – Uncheck to disable on this array.
• Enable PDM – Uncheck to disable on this array.

4. In the Select Physical Drives diagram, click the drives to add them to your array.
The drive carriers turn blue when you click them. The physical drives’ ID numbers appear in the field below the diagram.

5. When you have finished your settings and choices, click the Submit button.
The new array appears in the list.

• If you are done creating disk arrays, click the Finish button.
• To create additional disk arrays, click the Create More button.

Once the disk array is created you can go have to create the Logical Drives. Follow the steps below to create a new Logical Drive.

To create a logical drive manually:

1. Do one of the following actions:
• Click the Logical Drive icon.
• From the Storage menu, choose Logical Drive.

2. Click the Create Logical Drive button.

3. Click the radio button of the disk array you want to use and click the Next button.

4. Accept the defaults or make changes:
• Optional. Enter an alias in the Alias field.
Maximum of 32 characters; letters, numbers, space between characters, and underline.
• Choose a RAID level.
The choice of RAID levels depends the number of physical drives in the disk array.
• In the Capacity field, accept the default maximum capacity or enter a lesser capacity and
size in MB, GB or TB.
Any remaining capacity is available for an additional logical drive.
• Choose a Stripe size.
64 KB, 128 KB, 256 KB, 512 KB, and 1 MB are available.

The Write Cache is always set to WriteThru when the Read Cache is set to NoCache.
• For RAID 6 logical drives, choose a Codec Scheme from the dropdown menu.
P+Q and Q+Q are available.
• If you want the PROMISE Utility to format your logical drives, leave the Format box
checked.

5. Click the Add button.
The new logical drive appears on the list at the right.
If there is capacity remaining, you can create an additional logical drive. Pegasus supports up to 32 logical drives.
