>Description:
	It looks like "bioctl <device> show disks" consistently
	returns an error:

# bioctl mfi0 show disks
 Disk Model/Serial                   Status       Size       Location
=====================================================================
bioctl: BIOCDISK_NOVOL: Invalid argument
#

	However, just "bioctl <device> show" lists both the logical
	volume and the disks:

# bioctl mfi0 show 
Volume Status       Size         Device/Label    Level Stripe
=============================================================
     0 Online       279G                mfi0    RAID 1    N/A  65535 seconds
   0:0 Online       279G         1:0.0 noencl <SEAGATE ST300MM0006     0003>
   0:1 Online       279G         1:1.0 noencl <SEAGATE ST300MM0006     0003>
# 


>How-To-Repeat:
	See above.

>Fix:
	By the looks of it, there's a missing handler for
	BIOCDISK_NOVOL in sys/dev/ic/mfi.c's mfi_ioctl() routine.
