3.3.1  Prerequisites 
The following prerequisites must be met in order to support a DR event or 
exercise under this scenario. 
3.3.1.1  Configure Virtual IP address on Production and DR Executives 
Select a single, virtual IP address that is routable to both the 
Production and DR Executives.  Configure this virtual IP address, in 
addition to each machine’s “real” IP address, on the network interface 
connected to the management subnet.  The management subnet is the 
segment in which the IPAM Agents are connected.  Configure the 
virtual IP address using the accepted method of defining IP addressing 
information on that platform.  For example, on Red Hat this can be 
done using system-config-network. 
3.3.1.2  Installation of IPAM on Production and DR Executives 
  During the installation of the IPAM software on both the Production 
and DR Executive, you should enter the virtual IP address when 
prompted for the IP address of the system and executive on the initial 
setup screens. 
3.3.1.3  Updated copies of default.incontrol and incstatus 
  If the IPAM Executive software is installed and running directly from shared 
storage device, this prerequisite is not required.  This is required if only the database 
itself is mirrored. 
  As indicated previously, you must keep current copies of the 
default.incontrol and incstatus files from the Production Executive on 
the DR Executive.  Both files are located in $INCHOME/etc.  When 
copied to the DR Executive, they must be named 
default.incontrol.primary and incstatus.primary, respectively. 
 
3.3.2  Disaster Recovery Procedure 
This section describes the procedure necessary to initiate a DR event or 
exercise under this scenario. 
3.3.2.1  Bring the DR Executive online 
  Enable the IP connectivity of the DR Executive by either physically 
connecting it to the network, or by enabling the switch port to which it 
is connected.
