| I have just imported the mfi(4) and mfiutil(8) into a 9.0-RELEASE tree to 
| try this out.
| 
| When booting up with two fresh drives attached, they show up as usable 
| JBOD disks. However, I cannot use mfiutil to create anything with them. 
| Every drive gives
| 
|    "mfiutil: Drive n not available"

You might want to include the output of:
	mfiutil show drives
and then the command you are trying to do to create a RAID with.

| mfiutil and clean disks?

I'm not sure if mfiutil can switch disks from JBOD mode to RAID.
I don't see any reason why it shouldn't.  It can't go from RAID to 
real JBOD mode since it doesn't have code to support that.

What was the syntax you used since usage is cryptic?  I've never
seen a MegaCli that couldn't access the card.  What I meant by
more recent MegaCli is earlier versions didn't have the JBOD
commands in it.  I have a 8.00.46 that knows about JBOD.

You are definitely in real JBOD mode with each drive being /dev/mfisyspd0
and /dev/mfisyspd1.  So you can access the drives as those to do some
experiments with if you want to.
