1238.0. "Can Alpha (OpenVMS) act as load host ?" by COMICS::SHELLEY (Lead, follow, or get out the way) Thu Mar 20 1997 06:23

    Hi,
    
    A customer has a RT vax 3305 running VAXeln that currently
    runs off a vax 4000-60 as a load host.
    
    They want to retire the 4000-60 and replace it with an Alpha 255/233
    as a load host.
    
    Will the Alpha 255/233 running OpenVMS Alpha 6.2 or 7.1 have the
    software necessary to act as a load host ?
    
    Thanks

1238.1How do UK CSC access Realtime Expertise Centre?BBPBV1::WALLACEjohn wallace @ bbp. +44 860 675093Thu Mar 20 1997 10:1620
    Do they just want to download their existing system image ? If they
    ever need to update it they need a VAX somewhere with VAXELN...
    
    Otherwise, DECnet-classic should work just fine. "Support" is moot.
    
    DECnet-OSI may be more of a problem. LANACP doesn't help enough; the
    download is more than just loading an image file, there's some phase IV
    DECnet stuff to tell the target its DECnet address and such.
    
    There's a specific VAXELN conference at HELIX::VAXELN but many of the
    players come here too. There's also a mail account at Helix::realtime.
    
    Allegedly there is an official route from the UK CSC (COMICS:: implies
    UK CSC?) to the Realtime Expertise Centre in the US where some good
    folks are available to help. I don't know how it's supposed to work, it
    would be handy to have that info available in the UK CSC.

1238.2As long as they have DECnetZYDECO::BODARealtime Expertise CenterThu Mar 20 1997 10:2712
There is no problem loading a VAXELN system image to a VAXELN target using
an OpenVMS Alpha system as the load host.  As long as they have configured
DECnet on the load host with service enabled (to recognize the MOP boot 
requests) and set the other target node characteristics, they can boot with
no problem.  I've done this several times with our OpenVMS Alpha Systems here.

Please remember that no other VAXELN development work can be done on the
OpenVMS Alpha system as those tools will only work on OpenVMS VAX systems.

Regards,

Alan

We collided John :-)

There was one gotcha regarding DECnet/OSI and its MOP V4 protocol 
and the KAV30 target.  However, that has been since corrected in 
the latest EPROMs for the KAV30 (ca Sept '94).  However, the other 
VAXELN targets should not have a problem booting either via 
MOP V4 or MOP V3.

Regards,

Alan
