Glad you got it back! Yes, when I was first playing with ZFS, I noticed

I did go into single-user mode and attempt to do ZFS-related commands,
which might explain the "no datasets available" once I was back in
multiuser! I would classify that as a bug, and one which is going to
cause all sorts of hair-pulling for administrators in the future. I
wonder what it's caused by.
In single user / is read only and so /boot/zfs/zpool.cache can't be
created/updated

The "import" technique I found on a forum somewhere, or possibly on a
Solaris mailing list. I was really sweating there for a moment...
So, is the disk toast, or can you still read anything from it (part
table, etc.)?
The ad6 disk (/backups) fsck'd cleanly without any missing files or
anomalies.
The ZFS pool that has two striped disks (ad8 and ad10) is fully intact
too, with no loss of data that I can see. I'll have to run a scrub
after I'm done copying data over to ad6, just to make sure though.
