Did you transcribe by hand? The closest would be:

    "Inquiry data has changed"

This just means that  the the EVA sent back a command with  "Inquiry Data
Changed"

w/o a traceback I can't really say what happened here with certainty. Given
the other probe messages somehow we seem to be re-scanning due to the other
system going down.

Try a 'boot verbose' and see whether on the surviving system that the disks
are being seen as going away by the ISP driver.

What's the connection topology, btw?
