We want to add two more 36Gb drives to the existing raid and vg configuration.
1. Do we add them via the controller? if so, is this process requires downtime or can it be done online? not to familiar with the "sasmgr"
2. Or just simply plug them in and vgextend? if so, how this affects the mirroring form the controller?

Re: rx3600 integrated raid
but best way is to create a new RAID Volume from your new drives and extend the VG with your new volume,
you can see the document on

Re: rx3600 integrated raid
So I can't add the new drives to the existing configuration unless a recreate it?
If I add the drives like you recommend I would end up with two Raid 1 within the same VG. How does the mirror handles a disk failure?
I found this command:
sasmgr add -D /dev/sasd0 -q raid -q level=1 -q size=34000 -q enc_bay=1:5,1:6
would this work?
