a new system including new Hd's all the way down to the RAM has been replaced. (including a new MSA 30)
HP says it doesn't cause corruption and not to worry. Microsoft PSS says they have 12 cases of other customers having the same issues and data loss. Hp says "no it doesn't". MS says "yes it does". i have been there and seen it, and I say "yes it does".
its a classic case of Godzilla's pointing fingers. in the mean time we are on pins and needles and are cutting more tape than a tape dispenser.
I'm looking for some insight of what others may have done to resolve this since HP cant get their own product fixed. Does anyone have this setup in production? what has been your experience?
thanks in advance!

Re: "scsi downshift error"
If you have replaced the whole MSA30, I wonder if this was a bad batch. Have tier 3 test on the power supply.

Re: "scsi downshift error"
Also, we have 2 other idetical units that suffer the same fate. Hp is saying a F/W fix is being worked on but its been 2 months now. it seemed to come up the most after a warm boot but only 1 or 2 times per 10 reboots.

Re: "scsi downshift error"
I dont see where the U320 Protocol is being comprimised despite the errors. It would be intersting to connect a scsi backplane analyzer and see for myself what is really happening.

SolutionWe are experiencing a similar issue, however I am inclined to believe that the downshifting issue is a symptom of some deeper, I/O problems with the hardware.
We randomly experience the same errors on roughly the same configuration as you did. The only viable theory I have stumbled upon was information regarding the lack of a battery backed write cache (BBSC) on the 5i controller. This, in turn, causes slow write speeds which may the source of the symptoms we are seeing.
Any additional information anyone could provide on this would be helpful.
Thanks!
