Note the '8 luns per target'.

Perhaps read the isp driver source.

Files missing in /dev, if any, would not affect kernel attach messages.


A belated comment on ccd vs raidframe vs lvm.  My impression is that ccd
is more or less deprecated and something that I would not choose to
start using.   So I would pick raidframe or lvm.  But I would also be
very wary of concatenating 8 disks to one, unless I viewed it as scratch
space.
