Issue :

Need to add Multiple routes for an IP Resource.

Description:

Requirement is to add multiple routes to an IP resource. By default, IP Resource accepts only one route using IPRouteOptions  . POSTONLINE trigger is helpful to over come this problem.

postonline trigger:

Invoked after the service group is online.

Example : Adding POSTONLINE trigger in below SG.

group ecds_web_01 (

        SystemList = { lcnecdsdb01u = 0, lcnecdsdb02u = 1 }

        AutoStartList = { lcnecdsdb01u, lcnecdsdb02u }

        )

Steps:

1) Check if you have any POSTONLINE trigger file in triggers directory

# ls -l  /opt/VRTSvcs/bin/triggers/

2) If no POSTONLINE file is there then copy a sample trigger file as below to the main trigger location.

# cp /opt/VRTSvcs/bin/sample_triggers/VRTSvcs/postonline /opt/VRTSvcs/bin/triggers/

3) Go to /opt/VRTSvcs/bin/triggers/ and create a file containing your command which you want to run in POSTONLINE.

Example : -  Created routeadd.sh file "/opt/VRTSvcs/bin/triggers/routeadd.sh".

4) Go to /opt/VRTSvcs/bin/triggers/ and open POSTONLINE file and append below line before exit of script.

system("/opt/VRTSvcs/bin/triggers/<yoursamplescript>");

Example :-  system("/opt/VRTSvcs/bin/triggers/routeadd.sh");

==============================================

File will looks line :

[root@server101 triggers]# cat postonline

……

……

system("/opt/VRTSvcs/bin/triggers/routeadd.sh");

exit;

[root@server101 triggers]#

====================================

Now, Enable the Trigger at Service Group level :

5) Enabling Trigger at SG

hagrp -modify <Service group name > TriggersEnabled POSTONLINE

===============================================

Service Group look like :

group ecds_web_01 (

        SystemList = { lcnecdsdb01u = 0, lcnecdsdb02u = 1 }

        AutoStartList = { lcnecdsdb01u, lcnecdsdb02u }

        TriggersEnabled = { POSTONLINE }

        )

========================================

Sample file of routeadd.sh for adding three routes :

Syntax : ip route add <IP> src <Gateway> dev eth0

#!/bin/bash

ip route add 10.x.x.36 src  x.x.x.x  dev bond0

ip route add 10.x.x.35 src  x.x.x.x  dev bond0

ip route add 10.x.x.42 src  x.x.x.x  dev bond0
