I wanted to suggest that if you restore (wow, good to have backups
at this size-scale!) - you should also benefit from recreating the
pool with ZFS over native disks, excluding the HWRAID from equation.
But Bryan said that first ;)

If you did a hard reset, it is unlikely that any kernel crash data
was created at all (there may be FMA and other logs, usually in /var/*
on the rpool, up till the point-in-time that the system froze).

Now, if there are kernel-panics, on a non-LiveCD installation, such
as when you tried to import the pool and it panicked, the system
should handle it by writing into (by default) the rpool/dump volume.
Then after boot, via SMF or manually, the "savecore" command runs to
convert this raw data into files (/var/crash/*) that can be inspected
by the mdb debugger.

This should get you started, unless it is already too late ;)
