Differences Between NS3000/V and NS3000/iX
The following paragraphs summarize differences between NS3000/V and
NS3000/iX. Make sure that you account for these differences that could
affect your network when migrating to NS3000/iX. For system migration
issues, refer to the MPE/iX Migration series for more information.
Differences in Hardware
Some NS3000/V hardware components are not part of an NS3000/iX network,
such as the ATP for terminal connections, and the INP for network links.
On an NS3000/iX network, the DTC provides connections for local or remote
terminals and serial printers. The DTC also provides MPE/iX access to
X.25 through a DTC/X.25 Network Access card. The Distributed Terminal
Subsystem (DTS) LANIC on the MPE/iX host is used for system-to-system
X.25 connectivity.
Unsupported Network Connections
Before migrating your network, identify any unsupported network
connections. The network connections that are not supported on NS3000/iX
networks are as follows:
* Manual-dial modems.
* Asynchronous SERIAL Network Link and bisynchronous link-level
protocol. To ease migration, you can convert Asynchronous SERIAL
network links to the NS3000/V Point-to-Point links which can be
converted to NS3000/iX. Point-to-point links use the LAP-B
protocol.
* Connections to DS/3000 nodes. DS network services are not
supported on NS3000/iX. If DS/3000 nodes are part of an existing
network, either migrate them to NS3000/V or maintain NS3000/V
connections to the DS/3000 nodes.
Differences in Configuration of Terminals and Printers
On NS3000/V networks, the SYSDUMP program is used to perform I/O
configuration which includes configuring terminals, printers, and other
I/O devices and drivers. On NS3000/iX, terminals and serial printers are
configured on the host (using NMMGR) and, if you are using PC-based
network management, on the OpenView Windows Workstation (using the
OpenView DTC Manager software). For more information on configuration
using your OpenView Windows Workstation, read Using the OpenView DTC
Manager.
PAD devices on NS3000/V are configured (using NMMGR) as part of the X.25
network configuration. On NS3000/iX with PC-based network management,
PAD devices are configured both on the host (using NMMGR) and on the
OpenView Windows Workstation (using the OpenView DTC Manager software).
(With host-based network management, PAD devices are also configured
using NMMGR.)
Differences in Configuration Files
NS3000/V network configuration files are separated into two files, the
NMCONFIG file, which contains link information, and the NSCONF file,
which contains the transport configuration and other subsystems you have
purchased such as SNA.
NS3000/iX systems have a single NMCONFIG.PUB.SYS file that contains
information for the network transport, for NetIPC and link-level logging,
and also for the Datacommunications and Terminal Subsystem (DTS).
NMCONFIG.PUB.SYS also contains information for any other subsystems you
have purchased such as SNA.
Differences in Network Services
Differences in the support of network services between NS3000/V and
NS3000/iX can affect applications that users may currently be running on
the NS3000/V network. These differences are:
* NS3000/iX supports PTOP for HPDESK only. Network users who are
running PTOP programs will need to convert them to NetIPC/RPM
programs before running them on an NS3000/iX network. Refer to
the NetIPC 3000/XL Programmer's Reference Manual and the Using
NS3000/iX Network Services for more information.
* Nowait I/O RFA is not available with NS3000/iX. Privileged mode
programs that use nowait I/O Remote File Access over an NS3000/V
network will need to be modified before they can be run on an
NS3000/iX network. Refer to Using NS3000/iX Network Services for
more information.
To Obtain Device Status Information
On MPE V systems, the SHOWCOM command returns status information
about communication devices such as Local Area Network Interface
Controllers(LANICs). On NS3000/iX systems, this information is available
with the LINKCONTROL...;STATUScommand.
