SunOS twinkie 5.10 Generic_125100-04 sun4u sparc SUNW,Sun-Fire-880
-->>I'll put the rest in an attachment as this will be a long post.
This message posted from opensolaris.org-->>This problem was with a V880 with attached storage, an A5200. The 880 is
configured with 2 disk bays and the A5200 is connected via fiber to 2nd channel
on the the pci-x dual host bus adapter.
-->>I have to admit I probably, unknowingly at the time, caused my own problem,
however I've now seen the zfs status out of sync on 2 different occasions.

twinkie># zpool status -x
all pools are healthy
-->>I tried clearing the faults in fmadm and rebooting and had the same
results. I was unable to bring the pool back online using any zpool commands.
-->>With the help of a friend, thanks Rick, we were able to determine that the
2 disks I had labeled were labeled with SMI instead of EFI. So after
repartitioning the 2 disks and having it labeled with EFI I got the proper
label attached. Once that was done I cleared the fmadm faults and rebooted.
Thank goodness the 1.3TB pool came back online.
-->>I'll be adding spares and redoing this, but for now I don't have to
recreate the entire thing.
