Upgrading the Recovery Partition
Copyright © 2010, Juniper Networks, Inc.
The recovery partition contains all files necessary to perform a clean installation of the
NSMXpress OS and its applications with default settings. It provides a last-resort recovery
mechanism. When the NSMXpress appliance is shipped from the factory, the recovery
partition files match the version of the NSMXpress OS with factory default settings.
Using the Recovery Upgrade option, you can make the current version of NSMXpress
available for recovery, displacing the existing files in the recovery partition. The factory
default recovery files are retained as an alternative recovery choice. Other versions are
deleted.
Recovery upgrade uses two sets of packages to create a set of files from which you can
perform a clean installation. One set makes up the NSMXpress OS, the other a set of
upgrade script packages. Both sets are usually retained in the local file system. The
NSMXpress OS set can also be downloaded form the Juniper Networks software
repository.
NSMXpress splits the recovery upgrade process into a preparation phase and an upgrade
phase. In the preparation phase, NSMXpress assembles a copy of the current version of
the image files in temporary workspace. In the upgrade phase, NSMXpress replaces the
old recovery image files, and installs the current version of the image files from the
temporary workspace into the recovery partition. By splitting the process into two phases,
NSMXpress minimizes the period of vulnerability while the upgrade itself takes place.
To upgrade the recovery partition, follow these steps:
Select System Administration > Maintenance > Update Recovery Partition.
