Ah, thanks.  I did in fact need to create /var/crash/openindiana2 (the
hostname is openindiana2).

root at nas2:/var/crash/openindiana2# mdb unix.0 vmcore.0
Loading modules: [ unix genunix specfs dtrace mac cpu.generic uppc apix
scsi_vhci zfs sd mpt ip hook neti sockfs arp usba stmf stmf_sbd fctl md lofs

Sorry, you have to run savecore twice.


# savecore
should write out the vmdump.0

The second
# savecore -vf vmdump.0

Will extract it.
