9.4 Configuring and Booting Satellite Nodes
9.4.4 Enabling Satellites to Use Alternate LAN Adapters for Booting
OpenVMS supports only one hardware address attribute per remote node
definition in either a DECnet or LANCP database. To enable a satellite with
multiple LAN adapters to use any LAN adapter to boot into the cluster, two
different methods are available:
• Define a pseudonode for each additional LAN adapter.
• Create and maintain different node databases for different boot nodes.
Defining Pseudonodes for Additional LAN Adapters
When defining a pseudonode with a different DECnet or LANCP address:
• Make sure the address points to the same cluster satellite root directory as
the existing node definition (to associate the pseudonode with the satellite).
• Specify the hardware address of the alternate LAN adapter in the pseudonode
definition.
For DECnet, follow the procedure shown in Table 9–4. For LANCP, follow the
procedure shown in Table 9–5.
Table 9–4 Procedure for Defining a Pseudonode Using DECnet MOP Services
Step Procedure Comments
1 Display the node’s existing definition using the following
NCP command:
$ RUN SYS$SYSTEM:NCP
NCP> SHOW NODE node-name CHARACTERISTICS
2 Create a pseudonode by defining a unique DECnet
address and node name at the NCP command prompt,
as follows:
‡Alpha specific
‡DEFINE NODE pseudo-area.pseudo-number -
NAME pseudo-node-name -
LOAD FILE APB.EXE -
LOAD ASSIST AGENT SYS$SHARE:NISCS_LAA.EXE -
LOAD ASSIST PARAMETER disk$sys:[] -
HARDWARE ADDRESS xx-xx-xx-xx-xx-xx
This command displays a list of the satellite’s
characteristics, such as its hardware address, load
assist agent, load assist parameter, and more.
This example is specific to an Alpha node.
For a VAX node, replace the command LOAD
FILE APB.EXE, with TERTIARY LOADER
SYS$SYSTEM:TERTIARY_VMB.EXE.
Table 9–5 Procedure for Defining a Pseudonode Using LANCP MOP Services
Step Procedure Comments
1 Display the node’s existing definition using the following
LANCP command:
$ RUN SYS$SYSTEM:LANCP
LANCP> SHOW NODE node-name
This command displays a list of the satellite’s
characteristics, such as its hardware address and
root directory address.
