OK. Hopefully this covers everything. So, we have:
/dev/sd/c0b1t2d3p4 for a whole partition, be it primary or logical
/dev/sd/c0b1t2d3p4s5 for a single slice in a partition

Leonard: one last choice before I set this in stone: do we use 'd' for
LUN or 'u'? Since we have to drop the device/subdevice concept, I
suppose we could reconsider the d/u choice too. IMHO 'u' is a little
more obvious, although I'll leave it at 'd' if you really think that's
better.

Regards,

Richard....
