Cisco Prime Network Registrar IPAM 8.3 Disaster Recovery Guide



1 Introduction

1.1 Overview

NOTE: This document describes functionality that is available only in Cisco Prime Network
Registrar IPAM 8.0 and higher.
NOTE: This document describes Disaster Recovery support for the IPAM Executive running
on supported Unix-based platform, Red Hat Linux. Disaster Recovery for the IPAM

Executive is not supported on Microsoft Windows platforms.

Environmental disasters, equipment failure, and power outages are scenarios that can

completely halt a company’s IT infrastructure. As part of the IPAM comprehensive

Business Continuity and Disaster Recovery (DR) solution,
IPAM offers a complete set of script utilities that enables customers to easily

transition to backup systems during an emergency - thus preventing negative impact
to normal business operations.

NOTE: IPAM 8.3 and later versions will not support Solaris. Refer to earlier versions of
IPAM documents if you want to use IPAM with Solaris support.

1.2 Major Functions

As part of the standard installation, IPAM already provides facilities for DHCP

Failover and Secondary DNS server configuration. These facilities ensure continuous
operation of these critical network services. During a DR event in which the IPAM
Executive is affected, the DHCP/DNS services continue to run autonomously, so

end clients will continue to operate. However, if the Executive is unavailable, then
configuration changes for DHCP/DNS cannot be made. To address this need, the

IPAM Executive can be configured for redundancy using the DR guidelines and

scripts described herein.

The following core functionality is provided with IPAM

Disaster Recovery (DR)

support:



Ability to mirror a Production Executive database



Switch remote agents between Production and DR executives
