Protect an Exchange cluster with a like-named (standby)
cluster
You can use the Application Manager to configure protection for an Exchange cluster
with a like-named (also known as a standby) cluster. These instructions also apply to
setting up multiple EVS (Exchange virtual server).
When you protect a cluster with a like-named cluster, the Application Manager moves
the EVS location from the source cluster to the target cluster. By moving the EVS, the
process of moving users and public folders from one server to another is not needed
because they will continue to use the same mail store on the target as they were on the
source. This, coupled with the ability to reduce the TTL (Time to Live) value of the EVS
DNS record (optional), allows a more seamless failover.
Next step: Verify that your cluster environment meets requirements
Like-named cluster prerequisites
Before you can use the Application Manager to protect a cluster with a like-named
cluster, you must complete the following:
● Each target server node must have the same version and service pack level of
Exchange as is installed on the source nodes.
● The target must have a resource group that has the same name as the resource
group on the source.
● The target resource group only needs to contain physical disk resources, which
MUST use the same drive letters that are used by the physical disk resources on
the source.
In a like-named environment, the Application Manager creates temporary name and IP
address resources on the target cluster for mirroring and replication. A DNS entry is
created based on the target owning node’s DNS server. If the source and target owning
nodes are configured to use different DNS servers, this can cause issues when enabling
protection. If you have issues enabling protection in this configuration, verify that the
source owning node’s DNS server is correctly set up to receive DNS zone updates from
the target owning node’s DNS server, or reload the forward and reverse zones using the
dnsmgmt utility
Note:
Like-named cluster support is only available for clusters running Exchange
2003. It is not available for Exchange2007.
