DL380 - SCSI bus fault occurred on Storage Box box 0

[REXILLA]

Hi- we're running Windows 2003 Server on a DL380 with a Smart Array 5i and 641 controller. Every few minutes our drives top responding for 10-15 seconds. After updating the array controller driver to the latest version and restarting; I was presented with the following event log alert:

Event Type: Warning

This may result in a "downshift" in transfer rate for one or more hard drives on the bus.

Can you tell whats the Driver version of Smart Array Controller?
Is there any tape drive connected to this??

The Smart Array software won't launch either. Click the shortcut and it nothing happens.

641 firmware version: Rev B, v2.32
Driver: 5.76.0.32

5i firmware version: Rev B, v2.58
Driver: 5.76.0.32

No tape drive attached.

I have seen this problem on Dl380G3 system, and if not mistaken HP have a internal document on this aswell..

Have you tried to reseat any of the components in the system yet?
IE : The Scsi backplane or the Sma641 controller?

Have a look at the following link aswell the same issue

Systems what i done, most of them required a replacement of the scsi backplane.
