Hi
Just wanting to confirm my logic for the following plan for an MSA2050
Customer has 2x RAID5 3+1 disk groups (one pool a, the other pool b).
Customer wants to fully populate array with same 600gb sas drives but end up with
2x RAID 5 9+1 disk groups in each pool plus 2 spares per pool.
Currently bays 1-8 are in use - no spares.
My plan
1. Create new DG in pool in slots 10-20 RAID5 9+1 in pool b
2. Remove existing 3+1 RAID5 DG in pool B forcing data migration to new DG in pool B
3. Using ESXi storage vmotion move data from pool A into new larger pool B.
4. remove old DG in pool A and recreate as 9+1 RAID 5 in slots 1-10 (using the 8 original drives and 2 new ones).
5. migrate data back into pool A from pool b using storage vmotion.
5. add two spares per pool in slots 21-24.
This means hopefully no downtime for the customer but will mean some performance impact.
It's either that or delete both DG's and start over re-creating the DGs with restoration from backup.
Hopefully I've not missed anything.
Any feedback appreciated. I've not touched an MSA for a while.
thanks.
