Last Friday, one of our V880s kernel panicked with the following message.This is a SAN connected ZFS pool attached to one LUN. From this, it appears that the SAN 'disappeared' and then there was a panic shortly after. Am I reading this correctly? Is this normal behavior for ZFS? This is a mostly patched Solaris 10 6/06 install. Before patching this system we did have a couple of NFS related panics, always on Fridays! This is the fourth panic, first time with a ZFS error. There are no errors in zpool status.
