Yes, you can do this, but you MUST have OpenManage Server Administrator (OMSA) installed: ftp.dell.com/.../OM-SrvAdmin-Dell-Web-WIN-6.5.0-2247_A01.10.exe
Configuration: PERC4/SC, mirror/RAID1, Windows 2003R2 1 disk failed in mirror and I bought new one. I think I know procedure - connect new to RAID, designate it to hot spare and start rebuilding from options of failded HDD. It will take very long time and I'll like to know if I can do designating and rebuilding from within system, not in controller's BIOS? - I want to server be able to work all time, even overloaded. PS. Sorry for my poor english.
PERC4/SC - Can I rebuild RAID1 in Windows (after replace failded HDD)?
