We are running a VAX-6300 with HSC70 to control the disks. We are now
considering connecting one of the MIPS machines (5800 series) to the HSC.
Now, there are two questions:
1. Is it possible at all? (ofcourse each will use different disks). Our
salesman says it'll work.
2. A more general question: Is it possible to limit inside the HSC access to
some disks for some hosts; i.e.: disk 0 to 7 will be access only by host A
and disks 8 to 10 only by host B? I couldn't find anything in the
HSC manual, so is it impossible?
Thanks in advance,

The current HSC interface doesn't seem to have code to do that kind of restriction although you can do it with the granularity of a whole HSC.

I think you can SET DEVICE/NOAVAILABLE, but as soon as the VMS node reboots it will see them again. From the Ultrix side it's easy to just not configure the VMS disks. > Thanks in advance, > __yehavi: > Yehavi Bourvine -- Alan Rollow alan@nabeth.enet.dec.com
