SUMMARY: invisible A1000 after Sol26 to Sol8 upgrade

From: Geoff Lane <zzassgl_at_twirl.mcc.ac.uk>

The most popular suggestion was to copy /kernel/drv/sd.conf from old system
to new.	  This had no effect - even though the contents were different
	
The solution that worked was suggested by himanshukhona - run devfsadm.

	# devfsadm -C -v -c disk

It made a number of changes to the device tree after which format could see
the missing A1000 again (though at a different location than the Sol5.6
system.)

Thanks for all the suggestions.
