MD3000 disconnected - meaning of event log message?

I don't see anything in the user guides for that...have you checked with support? They may be able to give you a quick answer. If not, try posting on the break fix forums below:

Hope that helps!

Our IT department did open a ticket, but I didn't find the answer very satisfying:

"I opened a ticket with Dell support and gave them all the MD3000 storage logs. The ticket number is SR # 842247131. According to the Engineer, the logs showed that there is nothing wrong with the storage array although it showed the operating system getting disconnected at around 10:37AM. This caused the two RAID controllers to automatically run self-test diagnostics. No errors we're found. At this point, I'll keep the ticket open just in case. I don't think this is a hardware issue."

I was hoping that someone here could provide additional information on the 1st message logged at the time this incident occurred. It seems like the MD3000 would be responsible for this situation and not the OS.

From my understanding of the 1st error?
The OS / Host(s) requested stand by pathing, instead of prefered pathing.
