be configured according to specifications listed in both
the hardware and software user documentation.
Loading HP DECnet SNA Gateway-CT Software
The DEC ChannelServer requires software to be loaded
into memory before DECnet SNA Gateway operation.
HP DECnet SNA Gateway-CT software is downline
loaded into the hardware across the Ethernet LAN from
an OpenVMS Integrity servers, Alpha or VAX system
acting as a DECnet load host system.
Most Integrity servers, Alpha and VAX systems run-
ning OpenVMS software are supported as Ethernet
load hosts for HP DECnet SNA Gateway-CT. Supported
OpenVMS configurations are described in the Open-
VMS Operating System for Integrity servers, Alpha and
VAX Software Product Description (SPD 82.35.xx and
SPD 25.01.xx).
DECnet SNA Gateway Management Software
DECnet SNA gateway management software, which is
part of the DECnet SNA Gateway-CT, provides configu-
ration and management functions for use with HP DEC-
net SNA Gateway for Channel Transport. This man-
agement software allows the gateway administrator to
configure the software executing in the DECnet SNA
Gateway-CT system. The administrator can set up pa-
rameters relating to lines, circuits, physical units, logical
units, and other key variables necessary for network-to-
network communications between the DECnet and SNA
networks. In addition, the software allows the adminis-
trator to manage and diagnose problems related to the
HP DECnet SNA Gateway-CT.
DECnet SNA gateway management software is required
on the HP load host node for HP DECnet SNA Gateway-
CT. It must also be present on any other OpenVMS
node where users want to manage an HP DECnet SNA
Gateway-CT and the DEC Channel Server. It is strongly
recommended that the software also be installed on
OpenVMS systems in order to facilitate debugging func-
tions where IBM Interconnect application programs are
developed using any of the DECnet SNA Programming
Interface products.
Gateway management software includes DECnet style
network management tools for configuring, controlling,
monitoring, and troubleshooting the DECnet SNA Gate-
way product. These activities are generally performed
by the HP system manager responsible for the desig-
nated load host node. Most management functions are
performed from a node on the HP network rather than
at or on the Gateway itself.
Management of the DECnet SNA Gateway should be
viewed as part of the HP environment, while manage-
ment of the lines and/or channel connecting the DECnet
SNA Gateway to the IBM system is a joint responsibility
of the IBM and HP system managers.
DECnet SNA gateway management software allows an
HP system operator to bootstrap or restart a DECnet
SNA Gateway remotely and provide configuration and
initialization facilities for the DECnet SNA Gateway.
Problem Isolation and Determination Tools for the
Gateway
In addition to event logging and error counters, a wide
range of fault isolation tools are included.
Trace capabilities SNATRACE and NETTRACE for
OpenVMS are provided with HP DECnet SNA Gateway-
CT to help debug application programs as well as assist
in identifying system problems. An operator can run a
trace at the Circuit, Physical Unit (PU), or Session level,
and then format the data on a specified HP system. The
trace features are helpful in identifying an error for re-
medial action.
A snapshot monitoring utility is provided to display on an
HP host-controlled terminal the status of the Gateway’s
buffer availability, the number of SNA sessions currently
in progress, and other information that pertains to both
the DECnet and SNA networks.
If an irrecoverable error should occur during operation
of the DECnet SNA Gateway system, a memory image
may be dumped to a designated Ethernet attached In-
tegrity server, Alpha or VAX host. This memory image
may then be provided to your HP support personnel for
problem diagnosis.
INSTALLATION
Installation services from HP are recommended for
a customer’s first purchase of this software product.
These services provide for installation of the software
by an experienced HP installation specialist.
