Exchange 2010 DAG backup over backup LAN
Hi, my master server is a cluster master server on RedHat 5 (NBU 18.104.22.168). The master server name is a virtual name and it is tied to a backup LAN IP address. It does not link to any production LAN IP address. The Exchange team has setup a new Exchange 2010 DAG. I found the DAG name is a virtual name and it is tied to a production LAN IP address. It does not link to any backup LAN IP address.
When we tested the backup, the backup job failed with status 26. I checked and found it tries to communicate from backup LAN IP address of the master server to the produciton LAN IP address of the DAG. As the two networks cannot talk to each other, the backup job failed.
My questions is:
In this kind of setup, how to do the configuration? The cluster master servers have two nodes, one active node and one passive node. Both nodes physcially connect to both bakcup LAN and production LAN. I checked with Exchange team and they said they cannot configure a backup LAN IP address for DAG. Thanks in advance.
