RDC and UNIX
>From decvax!duke!unc!lynn@Berkeley Mon Feb 1 10:42:31 1982
RDC should be able to diagnose ALL of your DEC hardware, subject to the
following restrictions.
1. You have the full set of diagnostics on floppies. (These are
delivered with your VAX, and run under their own stand-alone
supervisor.)
2. You tell the person at RDC that he will have to use the
stand-alone floppies (or cassettes, I guess, for a 750).
3. You have appropriate scratch media for all of your
peripherals.
It is a BIG help to both RDC and yourself if you can maintain a
diagnostic disk pack for a DEC hard disk. (DEC does not have to give
service contracts for any system without a DEC hard disk, but whether
they actually do or not is at the discretion of the local field service
manager.) A diagnostic disk has a VMS file system on it with all of
the diagnostics in the [SYSMAINT] directory. Your system can be
diagnosed MUCH faster in many cases if this is available, even though
it contains no programs not also available on floppies or cassettes.
The diagnostic supervisor can be booted directly off that disk whether
the rest of VMS is there or not, and the disk can be write-locked while
doing it. (Try booting from device SB0 or SM0 from your local console;
it will boot the diagnostic supervisor from a massbus disk (SB0) or
RK07 (SM0) if the supervisor is on the disk.)
