A customer called and reported that a server could not start up and the error message was regarding missing NTLDR.
Arrived on site and checked the server, which is in a secured location with no physical access except to a few trusted employees, and found that its RAID configuration was lost - all 4 drives showed READY instead of (for example) ONLINE-A00 .
I reconfigured the array back to its original state (4x500GB HDD's in a RAID 5, no HS) and it booted into Windows more or less normally albeit slowly. I checked the Intel RAID web console and found my array is performing a background initialization.
When I disabled IPSec and rebooted the RAID controller lost its configuration again and the RAID must be reconfigured by pressing Ctrl+E during the RAID Bios display.
I can configure the RAID in the BIOS then restart without issue, even boot to a boot disk then reboot and maintain the configuration. It seems to only be in Windows that this is occurring.
Intel S5000VSA Mainboard, Windows 2003 x64 Enterprise, Xeon CPU, server is just under 3 years old.
What could be causing this issue?
How do I fix it?
