9.4 Configuring and Booting Satellite Nodes
Table 9–7 (Cont.) Procedure for Creating Different LANCP Node Databases
Step Procedure Comments
2 Locate LAN$NODE_DATABASE.DAT files in the systemspecific
area for each node.
On each of the various boot servers, ensure that the
hardware address is defined as a unique address that
matches one of the adapters on the satellite. Enter the
following commands at the LANCP command prompt:
‡Alpha specific
‡DEFINE NODE node-name -
/FILE= APB.EXE -
/ROOT=disk$sys:[] -
/ADDRESS=xx-xx-xx-xx-xx-xx
If the LAN$NODE_DATABASE.DAT files are
copies of each other, the node name and the FILE
and ROOT qualifier values are already set up.
You need only specify the new address.
Once the satellite receives the MOP downline load from the MOP server, the
satellite uses the booting LAN adapter to connect to any node serving the system
disk. The satellite continues to use the LAN adapters on the boot command line
exclusively until after the run-time drivers are loaded. The satellite then switches
to using the run-time drivers and starts the local area OpenVMS Cluster protocol
on all of the LAN adapters.
For additional information about the NCP command syntax, refer to DECnet for
OpenVMS Network Management Utilities.
For DECnet–Plus: On an OpenVMS Cluster running DECnet–Plus, you do not
need to take the same actions in order to support a satellite with more than one
LAN adapter. The DECnet–Plus support to downline load a satellite allows for
an entry in the database that contains a list of LAN adapter addresses. See the
DECnet–Plus documentation for complete information.
9.4.5 Configuring MOP Service
On a boot node, CLUSTER_CONFIG.COM enables the DECnet MOP downline
load service on the first circuit that is found in the DECnet database.
On systems running DECnet for OpenVMS, display the circuit state and the
service (MOP downline load service) state using the following command:
$ MCR NCP SHOW CHAR KNOWN CIRCUITS
.
..
Circuit = SVA-0
State
Service
.
..
= on
= enabled
This example shows that circuit SVA-0 is in the ON state with the MOP downline
service enabled. This is the correct state to support MOP downline loading for
satellites.
Enabling MOP service on additional LAN adapters (circuits) must be performed
manually. For example, enter the following NCP commands to enable service for
the circuit QNA-1:
