Pre and Post Power On Steps
Site Recovery Manager can run a command from the Site Recovery Manager server at the
recovery site before and after powering on a virtual machine. A common use case is calling a
script to perform actions such as making changes to DNS and modifying application settings on
a physical server. Running a script inside of a virtual machine is also supported as a post power
on step.
Site Recovery Manager can also display a visual prompt as a pre or post power on step. This
prompt might be used to remind an operator to place a call to an application owner, modify the
configuration of a router, or verify the status of a physical machine.

NOTE: A prompt pauses a recovery plan until an operator clicks “dismiss” in the Site Recovery
Manager user interface.
IP Customization
The most commonly modified virtual machine recovery property is IP customization. The
majority of organizations have different IP address ranges at the protected and recovery sites.
When a virtual machine is failed over, Site Recovery Manager can automatically change the
network configuration (IP address, default gateway, and so on) of the virtual network interface
card(s) in the virtual machine. This functionality is available in both failover and fail-back
operations.
There are multiple IP customization modes in Site Recovery Manager. For example, it is possible
to create an IP customization rule that maps one range of IP addresses to another. In the figure
below, an administrator has mapped 10.10.10.0/24 to 10.10.20.0/24.
Figure 29. IP Customization Rule
Continuing with the example above, a virtual machine containing one virtual network interface
card with IP address 10.10.10.50 will be reconfigured to use IP address 10.10.20.50 when it is
failed over. When the same virtual machine is failed back to the original protected site, Site
Recovery Manager will change the IP address back to 10.10.10.50.
