Additional startup scripts may be included in the configuration using the start_script command.
The files in the start_script command will be placed in a location for tftp transfer to sibling
switches that initialize using the –u option. A common use of the start_script command might be
to propagate gated configurations to all members of the Surviving Partner group. Absolute path
names must be used. Using multiple commands allows inclusion of multiple scripts. For
example:

The vrrpd_script command allows a user defined script to be run when vrrpd changes
state. This script is called at the end of the zspconfig created vrrpd.script. See vrrpd –s for a
description of when the scripts are called. zspconfig sets up vrrpd to call vrrpd.script. The
vrrpd_script command in zspconfig places a call to the user-defined script at the end of
vrrpd.script file. The following example would call the my_vrrpd_script each time
vrrpd calls its –s provided script:

NOTE: The my_vrrpd_script is not called from a different process thread. Therefore if
my_vrrpd_script crashes or has long delays, it will crash the vrrpd, or cause delays in
the Surviving Partner failover. To protect against this, write the script to launch a second
script in a background shell. The advantage to calling the user provided script in the same
process thread is that it gives synchronized control over the failover process for those who
want it.

OUTPUT FILES
The output of zspconfig is a set of configuration and script files. The configuration files
configure vrrpd and zlmd daemons. The vrrpd and zlmd daemons combined with the script
files run the Surviving Partner. This is a list of all configuration and script files:
configure vrrpd and zlmd daemons. The vrrpd and zlmd daemons combined with the script
files run the Surviving Partner. This is a list of all configuration and script files:
/etc/rcZ.d/S70Surviving_partner
The main startup script that starts the Surviving Partner by
running zconfig, ifconfig, zlmd and vrrpd. zspconfig prompts
running zconfig, ifconfig, zlmd and vrrpd. zspconfig prompts
the user to run this script. This file can be saved with
zsync to automatically start the Surviving Partner at switch

Configuration script for the VRRP daemon. This configuration
