Configuration Requirements
The following configurations are required for a network switchover.
Hardware Configuration
The following hardware configurations are required for network
switchover:
* The NS LAN must be separate from the TIO/X.25 LAN.
* All DTC SNP cards used for an X.25 LAN network on the home system
must be dedicated to the home system or the home and alternate
system. No other systems can use these SNPs.
_________________________________________________________________
NOTE X.25 communications will be disrupted during a switch over.
_________________________________________________________________
* Both the home and alternate systems must use the OpenView DTC
manager.
Network Configuration
Two configuration files are required on the alternate system:
* NMCONBAC.PUB.SYS containing the alternate systems standard
configuration. The standard configuration for the alternate
system must contain:
* For terminal I/O:
* The same TIO/X.25 Link configuration (for example,
LINK.DTSLINK) as the home system.
* The same TIO configuration (DTS subtree) as the home
system. (Additional terminals and printers can be
configured, but the file must contain the same
profiles and nailed port configuration as the home
system.)
* NMCONMN.PUB.SYS containing the configuration required for a
switchover. The switchover configuration for the alternate system
must contain the following:
* For the LAN Network:
* The same nodename as the home system.
* The same LAN IP address as the home system.
* The same 802 address as the home system. (This will
override the chip 802 address.)
* For X.25 Network:
* The same X.25 NI configuration (for example, the
NETXPORT.NI.X25NET subtree) as the home system.
* For Terminal I/O:
* The same TIO/X.25 Link configuration (for example,
LINK.DTSLINK) as the home system.
* The same TIO configuration (DTS subtree) as the home
system. (Additional terminals and printers can be
configured, but the file must contain the same
profiles and nailed port configuration as the home
system.)
Network Directory Configuration
The alternate system must contain the same network directory
(NSDIR.NET.SYS) as the home system.
OpenView DTC Manager Configuration
The DTC configuration required on the OpenView DTC Manager workstation is
as follows:
* The home and alternate systems must both reside on the OpenView
DTC Manager (OVDTCMGR) Network Map.
* For each DTC being used for TIO/PAD traffic on the home and
alternate system, there must be two configurations:
* A standard DTC configuration with terminals and PAD
connections configured for either switching or connecting
to a host (home or alternate) system as desired.
* A switchover DTC configuration where all nonswitched
(directly-connected) terminal and PAD connections are
configured to connect to the alternate system.
