Thanks for a quick reply, Scott.

I added ispfw_load="YES" to /boot/loader.conf and now system can boot up 
fast. 
# camcontrol devlist -v
scbus0 on isp0 bus 0:
<DGC RAID 5 0217>                  at scbus0 target 125 lun 0 (pass0,da0)

scbus1 on isp1 bus 0:

Next question is can I do multipath with ISP driver?   The EMC AX100 has 
two "processors" for redundancy.
