if I have aggregate made of 13 disks (RAID-DP, RAID group size - 13 disks) and want to add 2 disks to the aggregate, what size of RAID group will I have after extension and how many parity drives?
I am afraid, what these two disks will be assigned as parity disks, because I use not full RAID group for aggregate extension.
Solved! SEE THE SOLUTION

netapp box will tell you it needs at least 3 disks (to open up a new raid group with 2 parity and 1 data).
you should rise the raidgroup size to 15, then add 2 disks, i think thats what you are trying to do.
btw, in higher ontap versions, the aggr add command will opt to show you a preview of what is happening, be sure to use that preview
