RAID 5EE (where E stands for Enhanced) is a RAID 5 layout with an integrated hot-spare drive, where the spare drive is an active part of the block rotation scheme. An example of such RAID layout is in the table below:

To create a RAID 5EE object

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

or select the Create Virtual Block RAID & Autodetect on the Create menu

>A Virtual Block RAID object will appear on the Drives panel
2Drag the required partitions from the Drives panel to the Parents tab

Click to expand/collapse Other ways to add objects

3Select RAID 5EE on the RAID type

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 RAID 5EE. If this order is incorrect, you must change it by dragging the parents to place them in the correct order.

Object control buttons

The RAID block size and Offset (in sectors) parameters must be set the same as for the original RAID 5EE.

You also need to specify Block order for virtual RAID 5EE You may select it on the Block order drop-down or shortcut menu.

If the those parameters are not correct, data on the parents will not be damaged, but files from the RAID 5EE cannot be recovered.

Note: You may check how correctly you have reconstructed the original RAID 5EE. Find a file and preview it. If the file appears correct, you have created a correct RAID 5EE layout.

>The RAID 5EE 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.
