I am unclear on when clear is the right command vs online. I have
not gotten consistent information from Oracle. Can Richard (or someone
else) please summarize here, thanks.

Yeah, hindsight and all that. But at the moment I hit return on
the zpool replace we still only had one of three trays faulted on the
3511 ... sigh.

Oracle support recommended a reboot (which did clear the ZFS
issue). I was not at the office to try to get a better solution out of
Oracle.
Now this morning, the original tray in the 3511 that failed is
offline again, but .... this time it is not the bug we have run into,
but a genuine failure of more than one drive in a RAID set. So now I
am zpool replacing the faulted LUNs (and have asked that no one reboot
any 3511's until I am done :-)
