NOTE: Configuring monitored_subnet_access as FULL (or not configuring
monitored_subnet_access) for either of these subnets will cause the package configuration
to fail, because neither subnet is available on all the nodes.
Creating Subnet-Specific Package Control Scripts
Now you need to create control scripts to run the package on the four nodes.
IMPORTANT: In a cross-subnet configuration, you cannot share a single package
control script among nodes on different subnets if you are using relocatable IP addresses.
In this case you will need to create a separate control script to be used by the nodes on
each subnet.
In our example, you would create two copies of pkg1’s package control script, add
entries to customize it for subnet 15.244.65.0 or 15.244.56.0, and copy one of
the resulting scripts to each node, as follows.
Control-script entries for nodeA and nodeB
IP[0] = 15.244.65.82
SUBNET[0] 15.244.65.0
IP[1] = 15.244.65.83
SUBNET[1] 15.244.65.0
Control-script entries for nodeC and nodeD
IP[0] = 15.244.56.100
SUBNET[0] = 15.244.56.0
IP[1] = 15.244.56.101
SUBNET[1] = 15.244.56.0
Reconfiguring a Package
You reconfigure a package in much the same way as you originally configured it; for
modular packages, see Chapter 6: “Configuring Packages and Their Services ” (page 279);
for older packages, see “Configuring a Legacy Package” (page 375).
The cluster, and the package itself, can be either halted or running during package
reconfiguration; see “Reconfiguring a Package on a Running Cluster ” (page 386). The
types of changes that can be made and the times when they take effect depend on
