RAID 5E (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:
where PD and SP stand for Parity of Data and Spare Part.
To create a RAID 5E object
or select the Create Virtual Block RAID on the Create menu
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 5E. If this order is incorrect, you must change it by dragging the parents to place them in the correct order.
The RAID block size and Offset (in sectors) parameters must be set the same as for the original RAID 5E.
You also need to specify Block order for virtual RAID 5E You may select it on the Block order drop-down or context menu.
If the those parameters are not correct, data on the parents will not be damaged, but files from the RAID 5E cannot be recovered.
Note: You may check how correctly you have reconstructed the original RAID 5E. Find a file and preview it. If the file appears correct, you have created a correct RAID 5E layout.
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.
