This is more informational than anything else, hopefully saving someone some troubleshooting time.
A few days ago one of my servers started slowing down to the point where even if I could get it to log on it hung before the desktop finished loading. After an embarrassingly long time and a lot of messages about failed hard drives later, I figured out that the network port on the physical unit where the ISCSI drive was stored was going out. Fortunately it had a second network port. Switching to the second port got rid of all the issues.
