Raid 1 after OS install??

[Bandit T.]

We have ML370 G5 that came with one 146gb drive that I had to install the OS on to get things going. Is it possible to still setup RAID even after the OS has been installed?

What you can do is make a RAID 0 on that HDD install the OS and once you get more drives you can migrate your RAID level. But if you install windows with no RAID created your data will be lost if you create a RAID.
