SA5304 migration, expansion RAID 1+0 to ADG
setup: DL380G2, SA5304, Win2K Pro, 2x18GB RAID 1+0, stripe 16KB
target: 6x73GB ADG
Waiting for replacement battery for the 5304 to arrive before I proceed but would like to confirm the procedure.
So, is this right:
1. remove 18GB #0
2. replace with 73GB and wait for rebuild
3. remove 18GB #1
4. replace with 73GB and wait for rebuild
5. insert 73GB #2-5 and migrate to ADG
Will this also expand the array to the new size ?

Re: SA5304 migration, expansion RAID 1+0 to ADG
I replied to a forum recently on this and someone else said you can increase the size of the physical disks. I don't know about migrating to ADG though.
I don't recommend using ADG. I had it on one of my servers and the performance overhead only really became apparent when I rebuild it without the ADG. I'd suggest you're better off using an "offline or hot" spare drive. You don't have the performance overhead then (it was fairly significant).

Re: SA5304 migration, expansion RAID 1+0 to ADG
As for ADG: I need redundancy over performance. Perhaps it's HP's implementation of ADG that's the issue. I plan on also trying an Adaptec 2230SLP with RAID6 and see how that goes.
Yes, I know the odds of a second failure during a RAID5 rebuild are low but considering a rebuild can take days I cannot take that chance.
