Recently we purchased an HP Proliant ML150 G3 server. I configured 2 SATA HDD in a hardware mirror and installed Windows 2003 R2 SP2. I configure it as a DC, Antivirus server, WSUS and SQL server. One day I notice mirror isn't working properly and it actually is as if it was not configured at all. Tried to fix it, without much success and after 2-3 hours tech support from HP I was told that I would need to reconfigure mirror at startup again and this would cost me OS and everything else. Now, I don't want to lose all data on the disk. Basically, I want to be able to recreate the mirror and then restore the entire original configuration and at same time not mess up my AD. What's the easiest way to go??!! I am thinking about Acronis, but I have a bad experience with it. Alternatives?
