Smart Array 641 - U160 disabled CRITICAL

[lhosbrough]

In the ADU, I see this message under the controller parameters. We have 3 U320 SCSI drives in the array, and are getting horrible throughput ever since the array had to be rebuilt. We tried going to a local disk to rule out the DAT drive, but even that was slow. I see the controller message but have no idea how to go about changing it, or if this is even the problem.

How do I up the speed on this? It used to do 300+MB throughput, now highest is low 200's.
