I have an update on this... After talking to a friend who deals with
Solaris all the time, he was thinking it was a bug in EFI. Based on
what Richard was thinking too, I took a smaller LUN that was below 2TB
and changed the label from EFI to SMI. It works now. I can move the
LUN back and forth between the two servers. So I guess I either redo
all my LUNs to support SMI and let ZFS RAID them together or I wait
and see if a patch comes out for this issue.
