arcserve-KB : How to specify 1 IP for RHA management and a different IP for replication

Last Update: 2016-04-25 14:34:54 UTC

Description:

Depending on your network setup and the location of your masters, replica's, and the CA ARCserve RHA manager server, you may want to specify 1 IP for your master or replica for communication from the CA ARCserve RHA manager and a different IP for replication traffic.  When you create your scenario the hostname you enter should resolve to an IP, this is the IP that will be added to the scenario for that server for it's management IP.  The CA ARCserve  RHA manager will use that IP to communicate with that server and make changes to the scenario or start the scenario, or switchover.  Unless another IP address for this host is manually added for replication CA ARCserve RHA will go ahead and use the IP it already has for this server for replication.  If you have another IP address for this server that you would prefer  CA ARCserve RHA uses for replication traffic please see the steps below.

Solution:

To specify a different IP address for replication for your master or replica server please expand the scenario in the left hand pane and click on the server in question.  In the right hand pane go to the properties tab and expand 'host connection'.  By default the management IP should be there and the replication IP should be blank, CA ARCserve RHA will automatically use the management IP for replication unless you otherwise specify a 2nd IP.

As you can see above the only IP listed is the IP that was resolved for the host in question (SQL2008M).  The CA ARCserve RHA manager will now use this IP to communicate with the host SQL2008M for management purposes.  If I want this host to use a different IP for replication traffic I would need to enter it into the 'Replication IP Address' section as follows:

Above you can see a new IP on a different network/subnet has been entered.  All data traffic will flow out of and into this network IP instead now.  Please do not forget to go to the properties tab for the other server(s) in your scenario and update their replication IP's as well.  When finished hit the save icon on the top left, you can now run the scenario.
