p400 controller RAID0 --> RAID1+0

[wbmd]

I have a P400 cntrl, and orginally had 2 two drives configed as a raid1+0 set. I had one of the drives pulled and placed into a mirror system. When the New server booted, the drive came up, but was recognized as a single disk (RAID0), not a member of a pair. My question.... Is there a process / Document that would explain / allow me to create a RAID1+0 on the new system using this disk and a new disk, while allowing me to keep the data intacked?

hello wbmd!

first of all, do you have BBWC?
if you have, you can do the migration.
