Each FC equipment I know of will issue a FC reset upon booting and 
OmniOS will pick that up. However, there is of course also a means of 
having the OmniOS box perform a FC reset on the bus which would also 
spurr a disk discovery, after which ZFS will happily import your 
formerly exportet(!) zpool without fuss.
