If drives had beed set as JBOD (on disk format not related to disk
controller)
then drives themselves should work on any machine and controller and OS
using OpenZFS.
Of course, it is best not to have SAS/SATA expanders and to use SAS
controller for SAS and SATA for SATA.
I would Leave all disks in and try to import with some another install
of both Openindiana, other illumos distro or even FreBSD and Linux with
ZFSOnLinux.
You can install OI Hipster in VirtualBox and then do zfs send/receive
system and user datasets to the main system disk/rpool to newly made and
empied BE. That way you can also boot OI Hipster and see if importing
behaves differently with newest illumos.
I bet it's some hardware failure to aether controller, expanders and/or
disk(s).

Ok, I identified the possibly faulty drives, and took them out. (Doing
a full test on them in another box)
Trying to import the backups zpool without the 2 drives (raidz2 so
should be ok):
zpool import -f backups
Hangs the server after about 10 mins. (I had top running, and it's
stopped updating)
Any ideas?
Regards
Richard

Removed the backups zpool (zfs export), shutdown and re-installed
the controller.
Booted up fine.
zfs import -f backups
^^Hangs at this point.
A while ago, i had a script running in cron to report on zpool
status, etc.
I must admit, my checking of the reports was a bit lax of late, and
I found the last few had this in the status:
NAME STATE READ WRITE CKSUM backups

So, looks like I might have at least 1 failed disk... will need to
try to identify the failed one(s), and pull it / them out.
Thanks so far, I'll update when I've had a chance to pull the
faulty disk(s).
