I've got two drives from a now-dead server, they were RAIDed, a mirror, I'd assume. I need to see if there's anything on them I need to transfer to the replacement, so I just shoved them into another Dell server, with a PERC 5 controller - I think that's what the dead one had. I fired up MegaRAID storage manager... but can't see any way to tell it to recreate that RAID. Anyone done this?
I wouldn't waste the time with MSM - I would simply use the BIOS configuration for the RAID storage which can easily look at the drives for RAID configuration and load it if it can find it.
Sorry, let me give my conditions a bit more: I don't think I can reboot the server - I believe it's currently in use as a development machine by one of the teams, so I can't play around with it.

Playing with this thing, I believe I want to create another drive group, not just add another RAID to an existing one, which just seems as though it could get really ugly. But when I click on the controller, I can then get to "Go To" -> controller, which will let me create a new virtual drive, but drive group is all greyed out still. Further, I don't see anything that would let me investigate what the documentation seems to call a "foreign RAID".
Hope that gives y'all a better picture of my environment.
let me see if I get this right... you don't want to play around with a server that's in production now but you are perfectly willing to play around with a server that's in production mode as long as it doesn't involve rebooting?
A development server that's in use is not a production server. Those are visible to the world. I don't think it's unreasonable to go in, add a drive group, add these drives to the group, and have it rediscover them and present them to me. Why is that not a safe thing? Other than the rediscover the RAID, it's no different than shoving an ordinary drive into one of the hot swap bays and mounting it under /mnt. <snip> mark
