Thanks for the quick response pressy!

No- the disks are not mirrored! This is development and we have only 2 disks!!

We do not have 'metareplace' but I did read the manual pages for 'luxadm' - Any idea where I can get more info/details?

I will look around for more info - Don't mean to be a slacker! but meanwhile it'll be of great help if you can provide more detailed instructions on 'how to do it'!

-- Our situation
Disk 0 -> root + some data
Disk 1 -> data

Disk2 -> New/replacement for Disk0
--

I was thinking something on these lines...

1. Replace Disk1 with Disk2
2. format - label- create partions on Disk2 similar to Disk0
3. ufsdump '/' to mount point under Disk2.
4. Replace Disk2 slot with Disk 1
5. shutdown
6. Replace Disk0 with Disk2
7. Bootup
8. Then what......?


Thanks!
