DNS failover (DFO) utility
The DNS Failover utility (dfo.exe) 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: \Program Files\HP\Storage Mirroring \dfo.exe” /dnssrvname
dnsserver_name /srcname source_name /srcip source_ip /tarname target_name /tarip
target_ip /verbose
The DFO readme (Readme_DFO.htm) file documents DFO syntax, known issues, and
workarounds. The readme file can be found in the folder where the Application Manager
is installed.
