Distributing the Configuration And Control Script with
Serviceguard Manager
When you have finished creating a package in Serviceguard Manager,
click Apply Configuration. If the package configuration has no errors,
it is converted to a binary file and distributed to the cluster nodes.
Copying Package Control Scripts with Linux commands
IMPORTANT In a cross-subnet configuration, you cannot use the same package
control script on all nodes if the package uses relocatable IP addresses.
See “Configuring Cross-Subnet Failover” on page 286.
Use Linux commands to copy package control scripts from the node
where you created the files, to the same pathname on all nodes which can
possibly run the package. Use your favorite method of file transfer (e. g.,
scp or ftp). For example, from ftsys9, you can issue the scp command
to copy the package control script to ftsys10:
scp $SGCONF/pkg1/control.sh \
ftsys10:$SGCONF/pkg1/control.sh
Distributing the Binary Cluster Configuration File with Linux
Commands
Use the following steps from the node on which you created the cluster
and package configuration files:
• Verify that the configuration file is correct. Use the following
command:
cmcheckconf -C $SGCONF/cmcl.config -P \
$SGCONF/pkg1/pkg1.config
• Generate the binary configuration file and distribute it across the
nodes.
cmapplyconf -v -C $SGCONF/cmcl.config -P \
$SGCONF/pkg1/pkg1.config
The cmapplyconf command creates a binary version of the cluster
configuration file and distributes it to all nodes in the cluster. This action
ensures that the contents of the file are consistent across all nodes.
