[Info-vax] HZS70 Unit number question

[Jeffrey H. Coffield]

I have two Alphas (not clustered) connected to a HSZ70 that currently
has units D0 through D5 showing as DKC0 through DKC5. DKC0 through DCK4
are mounted on one system and DKC5 is mounted on the other.

I have added some disks and want to add some new units but am concerned
about the SCSI disk numbering and the unit numbering. AFAIK the SCSI
controller takes a unit number (usually 7) so you could only have DKA0
through DKA6 on a bus.

I have read the CLI reference manual on the HSZ70 and can't see any
mention of there being a conflict between the unit number and the SCSI
addressing. It does say that a controller can present up to 8 units on
each target ID number. Both controllers show a SCSI target(s) of (0).

I only want to add two more units which would be DKC6 and DKC7 although
what the actual disk unit is is not important.
