SET HOST/DUP from a procedure?

» close window

The Question is:

 
VMS Version: All
 
HSCPAD (SET HOST/DUP...) in batch?
 
Why do the %%%PAD programs demand that their SYS$INPUT point
to a terminal class device?
 
We have a VERY large shop here where in order to solve the
problems associated with shadow copies, we've chosen to let
the HSJ50's do mirror copies instead - they're *TONS* faster,
the impact on cluster-wide I/O is very low and the entire load
is local to the controller pair.
 
However, the best we've been able to get is the unsupported
freeware program HSDSA. This program is unsupported, no source
code is available, it's not written very well (doesn't
understand EOF on its SYS$INPUT stream), it inserts superfluous
blank lines in the data coming back from the HSJs and does not
allow for easy determination of whether a command succeeded or
not.
 
How do we tell Compaq that we need something that we can use
in an OpenVMS batch job, preferably a command like:
 
$ DUP/NODE=HSJ001/TASK=CLI/OUTPUT=outfile hsj_command_string
 
...which sets $STATUS as appropriate to the completion code
of the command on the HSJ?
 
Please don't suggest SWCC (Storage Works Command Console).
Remember - we're an OpenVMS shop. We need to command the
HSJs from within an OpenVMS batch job in a lights-out,
unattended operation (that means no operator assistance,
no GUIs).
 
Thanx in advance for any help you can offer.

The Answer is :

 
  Please be aware of the ALPDUP01_062 ECO kit.
 
  The following kludge (or similar) may be of interest:
 
    $ SPAWN/WAIT/NOLOG/OUTPUT=OPA0: -
       SET HOST/DUP/SERVER=MSCP$DUP/TASK='task'/NOLOG 'Node'
 
  Pseudo-terminals could also be used, rather than OPA0:.
 
  The OpenVMS Wizard will check for an updated version of the HSDSA_SCRIPT
  for inclusion on the OpenVMS Freeware, and will pass this request along
  to OpenVMS Product Management.
