So are you saying although as far as my knowledge a Raid1 can have as many as 32 drives, this is looked at in Dell terms as a Raid level migration by adding additional drives, hence based on the table you had provided would need to migrate to Raid5 or Raid6.
Last question would be would the migration from Raid1 to 5 or 6, maintain the data that is currently on the vdisk?
It shows in the link that I posted that adding disk to a RAID1 is possible with resulting RAID 0, 5 or 6.
A RAID10 can be up to 32 disks.
Check what you see when you get in and see if your Source and Target RAID level can be RAID1.
Yes the Raid Level Migration and Online Capacity Expansion is designed to retain the information on the array, but again it is always recommended to have a validated backup before performing an operation.

Hello Gunners777,
It is always recommended to create a validated backup of your data before starting any action.
A RAID1 is only two drives, you cannot add more drives to this RAID level.
You could add the drives and do a Raid Level Migration on RAID1 to RAID5 or RAID6
See table on this link Source and Target level : https://www.dell.com/support/kbdoc/en-in/000129246/dell-poweredge-how-to-change-the-raid-level-of-a-virtual-disk
The document you have is good and this video may help.

If you want to maintain a mirrored array then you would backup, delete VD, create RAID10 with all the drives and restore from backup.
