Resize RAID Groups on a FAS 250

[Ironman2401]

We have a NetApp FAS 250 and I just added two disks to the system. I did not realize that the raidsize parameter was set to the previous number of disks in the system, so now I have two RAID groups which means I have two parity drives for the volume. We really wanted to use both the disks for data. I increased the raidsize by 2, but now I want to add the drives from the new RG to the other RG so we only have one RG with one parity drive.

From what I read in the KB this isn't possible without backing all our data up, destroying the volume, and then recreating it. Is there anyway around this or am I stuck with two parity drives now? Thanks.

I presume you have a vol0 and another volume,
What you can do if you have enough spares left :

create aggregate with the spares.Create new volumes , matching the size of your current volumes.Then do an NDMPcopy from source to target.(ndmpcopy <source> <target>.Rename old volumes, rename new volumes to the old names.Make the new "vol0" root volume ( vol options vol0 root ).You will have to reboot for the root volume to become the active one.Afterwards,you can place the original aggregate offline, destroy and make them spares again.

If the above scenario isn't valid, quickest way is to backup , destroy , recreate and restore.
