ODA X6 external redundancy

Hi,

I m working on a ODA X62-M.

For just curiosity, I dropped te RECO diskgroup and used the 2 free disks(as the result of dropping RECO diskgroup)  to recreate a new disk group named DATA2 using external redundancy.

When I dropped RECO , 2 NVMe disks(partitions) become available . (RECO was build on top of 2 disks-normal redundancy diskgroup , not counting the quorum..)

So I tried to create a new diskgroup named DATA2 with external redundancy using these 2 NVMe disks.

I used "asmca" for doing this.

asmca could see the disks as candidates (actually FORMERS), but it could not create a external redundancy group and encountered the following errors;
