D Using the DNS Failover (DFO) Utility
The DNS Failover utility (
dfo.exe
), which is part of the Exchange Failover utility installation, can be used in
the failover and failback scripts to delete and add host and reverse lookup entries so that the source host name
will resolve to the target IP address.
For example, the following command could be executed from a command line or included in a batch file:
“c:\Program Files\StorageWorks\Storage Mirroring\dfo.exe” /dnssrvname dnsserver_name
/srcname source_name /srcip source_ip /tarname target_name /tarip target_ip /verbose
