I have a client with as Dell SC440 server.

Original configuration:
Windows XP Pro (yes that is correct - hardware was bought with a view to upgrade to SBS at a later date).
2x 250Gb Drives Mirror On SAS 5/iR Controller
1GB Ram.

This has all worked well for a couple of years.

Now installing SBS 2008 (standard) on this hardware.

Ram has been upgrade to 4GB.
Old 250Gb Drives have been removed. 2x New 320Gb (Western Digital) drives have been installed.

Created new mirror array OK using RAID controller config at bootup. Says OK and status 'Optimal'.

Proceeded to install SBS2008 which took ages (about 4-5 hours).

On reboot I note raid config reports mirror 'degraded'. Requested Resync and raid util says resyncing - gets to about 5% resynced - then resets to 0 - tried several times - never gets above 5% resync (this is me looking at the SAS raid config status screen - i.e. before OS boots).

Have updated sas adapter to latest firmware from Dell.

Onsite now so 500 pts for suggestions which make some progress (or prove that its a hardware issue...)

Any pointers or suggestions ?
