[SGVLUG] FW: Video server

[Matt Campbell]

Hi Tom,

Oops, that is a major one isn't it?  :O

The board is configured as RAID 6 (like RAID 5, but with 2 parity disks
instead of 1).

I checked the logs and the RAID is not rebuilding or logging any sort of
errors.

There should be no contention on the bus, this is the only card in the case,
the only other thing plugged into the Mobo is the boot disk.

I have been working with a senior Adaptec tech on resolving the disk
incompatibilities with this controller card (they are surprisingly
ubiquitous).

Matt
