Can anyone give any input on what could be causing these errors? I'm see similar vmkernel errors on all 4 nodes in a cluster attched to our EVA8000. I'm not seeing any issues with any of the guests. I don't see anything of value in our Brocade switch logs or Commandview. Could it be a path going up & down? I would think I'd see something in the logs for the SAN devices.

They just look like normal status messages from the SAN. Though Retry Busy doesn't sound good?
We had a bunch of SCSI warnings in the VM Log files that we ended up suppressing on the Hitachi SAN side because they were not really warnings.
