Upgrading the Recovery Partition
The recovery partition contains all files necessary to perform a clean installation of the
NSM appliance OS and its applications with default settings. It provides a last-resort
recovery mechanism. When the NSM appliance is shipped from the factory, the recovery
partition files match the version of the NSM appliance OS with factory default settings.
Using the Recovery Upgrade option, you can make the current version of the NSM
appliance 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 NSM appliance OS, the other a set
of upgrade script packages. Both sets are usually retained in the local file system. The
NSM appliance OS set can also be downloaded from the Juniper Networks software
repository.
The recovery upgrade process is split into a preparation phase and an upgrade phase. In
the preparation phase, the NSM appliance assembles a copy of the current version of
the image files in a temporary workspace. In the upgrade phase, the NSM appliance
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, the NSM appliance minimizes the period of vulnerability while the upgrade
itself takes place.
To upgrade the recovery partition, follow these steps:
