How to clone a Sun V440 server with RAID?
September 13, 2010 1:33 PM Subscribe
I am trying to clone a Sun V440 server that is using the built-in raid (not disksuite). When I move the seed drive from the original server to the new server, the raidctl program complains that the drive is already part of another raid set (which it is), but I'd like to use it anyways as a seed for the new server. Any tips?
Response by poster: Nope. dd would copy, I think it's called, the DACstore from the original disks and the new server would refuse to use the disks since it would notice that the disks are part of another server's raid array.

Some of the config is stored on the RAID controller on the mobo, yes? We never used this feature, opting instead for DiskSuite, partly because of this.

do you have intermediary storage you could use? do a flash archive of the old server, and flash it down to the new server

A long shot, but could you do something like..
c0t0d0s0 - currently raidctl
c0t1d0s0 - clone
1) Break the raidctl mirror
2) metainit a new device using the raidctl device as the initial pane
3) add c0t1d0s0 (not under raidctl, just SDS) to the new SDS array
4) allow it to sync
5) Pull the disk and reverse it on the new server?
That seems like it would abstract the raidctl tagging away from it, as SDS devices are more or less valid portable filesystems that you can jerk around however you want, in my experience. Admittedly, my environment is almost entirely SDS, so I don't know if raidctl doesn't present itself as a raw disk that you could poke at like that.

You should really post this question to the Sunmanagers Mailing List. LOTS of Sun experts there. Just make sure to read the List Policy, How to Post, FAQ, etc fisrt.
Good luck!
