MS Disaster Recovery

Overview

F-2
Overview
If the Primary Management Server (primary MS) goes down due to an unre-
coverable hardware failure, management server duties can be migrated to an
online Standby Management Server (standby MS) using a simple backup and
restore process. After failover, the standby MS is able to perform all necessary
MS functions, including communicating with Enforcement Servers (ESs),
reporting, and making configuration changes. The NAC 800 backup/restore
process migrates the endpoint activity database, GUI users/passwords, and
other product configuration items, but does not include system level custom-
izations such as root and non-root user accounts or passwords.

Installation Requirements

The following items are required as part of the installation of NAC 800 and are
essential elements for recovery of an MS.
■ Primary and Standby Management Servers must each have their own
unique license keys, with equivalent settings (number of ESs and
endpoints)
Primary and Standby Management Servers must be assigned an
■
Internet Protocol (IP) address within the same network (so that when
the standby MS temporarily assumes the primary MS's IP, it is acces-
sible on the network)

Installing the Standby MS

A standby MS may need to be installed for the recovery of a failed MS. Allow
for proper configuration your hardware and software to accommodate the
following items in setup of a standby MS:
The standby MS should be installed to match the primary MS config-
■
uration:
• Same version of NAC 800
• Same version of test update RPM (RedHat Package Manager)
• Same version of BIND (DNS server software) plus any other custom-
izations
■ Standby MS should be installed with its own:
• IP address (different than that of the Primary MS)
• License to use without an Internet Connection
• Administrative UI user
