Working with RAID6 (Double Xor) Presets


R-Studio allows you to create and process RAID 6 Double Xor layouts with the following presets:

EVENODD

RAID DP

X-Code(2)

Adaptec 3805

In addition you may create your own RAID 6 configurations.

Creating a RAID 6 (Double Xor) object from a preset:

We will use the EVENODD preset as an example.

To create a RAID 6 (Double Xor) object

1 Click the Create Virtual RAID button and select Create Virtual Block RAID

or select the Create Virtual Block RAID on the Create menu

> A Virtual Block RAID object will appear on the Drives panel
2 Select RAID 6 / Double Xor on the RAID type
3 Drag the required partitions from the Drives panel to the Parents tab

Click to expand/collapse Other ways to add objects

• Control-click the Parents tab and select the required partition from the contextual menu ,

or

• Control-click the partition on the Drives panel, select Add to RAID on the contextual menu, and select the RAID object you want to add the partition to.

You may either make R-Studio to process your changes immediately or wait until you finish editing the RAID layout. Select or clear the Apply changes immediately checkbox on the Parents tab. Click the Apply button to apply the changes when are you through.

Note: Objects should be placed in the same order as they were in the original volume set. If this order is incorrect, you must change it by dragging the parents to place them in the correct order.

Object control buttons

Locate

Click this button to locate the selected object in the Drives panel.

Add Empty Space/Add Missing Disk

Click this button to add an empty space or missing disk object to the RAID

Remove

Click this button to remove the selected object from the RAID

Move Up

Click this button to move up the selected object in the RAID

Move Down

Click this button to move down the selected object in the RAID

Synchronize Offsets

Click this button to make the offsets the same for all objects in the RAID

Reset changes

Click this button to return the configuration to the initial state (after clicking the Apply button or immediately after loading)

The RAID block size and Offset (in sectors) parameters must be set the same as for the original volume set.

You also need to specify Blocks order (EVENODD for our case ) for virtual RAID 6 (Double Xor). You may select it on the Blocks order drop-down or contextual menu.

If the those parameters are not correct, data on the parents will not be damaged, but they cannot be recovered.

Note: You may check how correctly you have reconstructed the original volume set or RAID. Find a file and preview it. If the file appears correct, you have created a correct RAID layout.

> The Virtual Block RAID object can now be processed like regular drives/volumes

If R-Studio detects a valid file system on the newly created RAID object, a partition object will appear on the Drives panel. The Description Files for RAID Configurations topic shows the RAID description file for this RAID configuration.

You also may check the RAID consistency, if necessary. See the Checking RAID Consistency help page for details.
