PERC4e/DC - PV220s - raid conversion

[Robert von Bismarck]

Hello,

I have inherited a "funky" setup that I'd like to rationalise a bit.
We have a PE1850 running Centos 4.2 with a PERC4e/DC to which a PV220S is attached.
The PV220 has 5 76Gb disks in a raid5 + 1 hotspare and a single 300Gb disk as RAID-0.
Now I'd like to add a second 300Gb disk to that array and convert the RAID-0 to RAID-1 for a minimum of redundancy.
My question is : Can I do that without losing data, and can I do that through OMSA ?

Thanks for any hints/pointers,

Cheers,
