I'm running an r620 with esxi, connected to an MD1200 running RAID6, connected via perc h800
I need to add more storage and have 2 more MD1200s.

My question is more on 'how'.
Can I just chain the 2 new enclosures full of drives to the current, power them all on, then expand my RAID6 via OMSA somehow?
And without data loss?

I've read about expanding within an enclosure, but I've never chained 2 or 3 together while one has data already.

Wisdom appreciated!
