PERC4/DC : Convert single-disk RAID0 to dual-disk RAID1 andpreserve data?

[vincent at cojot.name]

Thanks for your reply.
I'll be trying to obtain OMSA and install it on this server.. Any extra 
information on the 'reconfigure' OMSA cmd?

For the record, here's what I tried from the BIOS and where it failed to 
perform as expected:

* Attempt 1):
- Create a single RAID-1 logical drive from the BIOS, reboot, get into
   MegaRAID BIOS again.
- Force offline the 'second' disk drive, this changes the logical drive to
   'degraded'.
- Force online the 'second' disk drive, and attempt to rebuild it from the
   menu (this failed because the PERC saw that this drive had already been
   seen)

* Attempt 2):
- Create a single RAID-1 logical drive from the BIOS, reboot, get into
   MegaRAID BIOS again.
- Force offline the 'second' disk drive, this changes the logical drive to
   'degraded'.
- Attempt to rebuild it from the
   menu without forcing the second drive 'online'(this failed because the
   PERC said it could only rebuild 'failed' disk drives )

* Attempt 3):
- Create a single RAID-1 logical drive from the BIOS, reboot, get into
   MegaRAID BIOS again.
- Go to the 'reconstruct' menu and select 'second disk drive', launch
   'reconstruct' on it.
- I interrupted the process after several minutes because I was a little
   mislead by the 'menu labels'. The menus only offered one choice (RAID-0)
   and mentionned I was reconstructing a RAID-1 to a RAID-0 from a RAID-1
   logical drive. I was unsure if that could be what I wanted so I bailed
   out.

Thanks for trying to help me out... :)
