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 the user to run this script. This file can be saved with zsync to automatically start the Surviving Partner at switch boot.

/etc/rcZ.d/surviving_partner/vrrpd.conf

Configuration script for the VRRP daemon. This configuration is used when the S70Surviving_partner script launches vrrpd. There is a line in this file for each router address vrrpd will manage. Or stated another way, each virtual_address command in the zspconfig configuration file results in a line in vrrpd.conf.

/tftpboot/zsp.conf<n>

zspconfig configuration file that contains the configuration of the sibling backup switches. The <n> is used to distinguish potentially more than one backup switch. This configuration file is placed in /tftpboot, and is retrieved via DHCP by a replacement switch on boot up.

/etc/rcZ.d/surviving_partner/dhcpd.conf

Configuration script used by dhcpd when the switch becomes master. dhcpd is used to serve replacement switches their configuration scripts. Namely a zsp_DC.conf file that can be input to the zspconfig with the -u flag.

/etc/rcZ.d/surviving_partner/dhclient.conf

If zspconfig is executed with the -u flag, a dhclient.conf file is created, and then dhclient is used to retrieve a zspconfig configuration file from the /tftpboot area of the Master switch.

/etc/rcZ.d/surviving_partner/vrrpd.script

Runtime script that executes each time the vrrpd changes state. This script starts and stops dhcpd, and toggles down bonding driver/RAINlink ports to force the nodes to a new Master switch.

/etc/rcZ.d/surviving_partner/zlmd.script

Runtime script executed by zlmd when a link goes up or down. This script modifies the priority of vrrpd, which in turn may cause the VRRP Master to move from one sibling switch to another.
