I have a raidz1 zpool ("Companion") I am unable to import. One of the
disks has physically failed and cannot be recognized by any computer,
and it is unlikely physical repairs or data recovery is possible.
No other disks are reporting errors. One other disk (not the failed
one) threw occasional errors during random reads, so I did a block
level copy onto a new disk with identical capacity from another
machine while the Solaris box was offline. It completed with no errors
and the newly cloned disk works perfectly. (I've done this before on
other pools without issues.)
So, at this time, all but one of the disks is present and fully
functioning and reporting no errors. A raidz1 should be able to
tolerate one disk failure. I have tried turning ZFS recovery mode on,
as well as tried deleting /etc/zfs/zpool.cache.
Can anybody give me an idea why I can't import the zpool? Anything I
can do to make it import, or at least recover the data?

Below are some of the more useful bits of output from the Solaris box:
