Scsi Errors.

[Justin Bennett]

It's a mirrored drive, the only thinkg that concerns me is that the 
volume was unusable, I couldn't access any data, so even if one drive 
failed I should still be running on the other, I'm thinking controller 
problem, This is the first time I've used these 2120S controllers. Maybe 
a driver problem. I've had issues with some adaptec card with certain 
intel chipsets and Redhat 7.x (what redhat 2.1 is based on) in the 
past.  I've submitted a support request to adaptec we'll see what happens.
