Yes:
$<systemdump
should do the trick.
Make sure your dumpadm is set up beforehand to enable savecore, and that
you have a dump device. In my case the output looks like this:
$ pfexec dumpadm
Dump content: kernel pages
Dump device: /dev/zvol/dsk/rpool/dump (dedicated)
Savecore directory: /var/crash/opensolaris
Savecore enabled: yes
Then you should get a dump saved in /var/crash/<hostname> on next reboot.

I can't help with your ZFS issue, but to get a reasonable crash

"savecore -L" on OpenSolaris.
That would be well and good if I could get a login - due to the rpool
being unresponsive, that was not possible.
So the only recourse we had was via kmdb :/ Is there a way to
explicitly invoke savecore via kmdb?
