OMU server pooling

[Netcon]

Hi

I'm setting up server pooling for 2 physical OMU 9 servers with 1 virtual interface.

1. How can I automate the switching of virtual interface when the primary server fails?

2. I understand that policies and node groups need to be the same on both servers. What about the managed nodes? Is it necessary to add managed nodes to both physical servers?

Thanks in advance.

To Automate Switch Over:

Once you set up server pooling, Its is pretty simple to automate. Server pooling switch over has 2 steps.
a) To diable the active virtual interface on the failed node.
/opt/OV/bin/ovbbccb -stop
ifconfig lanx:x inet netmask down

b) To enable the virtal interface on the failover node.
/opt/OV/bin/ovbbccb -start
ifconfig lanx:x inet netmask up

You can create a script for this logic and run a cron job when management process goes down.

2) IF you want to manage the nodes from the other server, it is good to add the nodes. If you are just looking for messages, just add a externel node. My suggestion is to have one management server for administration. You dont have to sync any policies.

One more item which you need to consider is the interface to troble ticket. you may need to switch over the functionality.

hi Shreks

Have you done policy sync before?

I was trying to use opccfgdwn to download policies from my primary server but always face syntax error with my dsf file.

I've used the method mentioned in the following thread:

You can easily do ir from the admin UI. in actions menu.

you can download the "DSF only" and use the same DSF file in scripts to sync..
