Upgrading the Recovery Partition
Note Recovery partition images are generated for major and minor updates and only in rare situations for
service packs or signature updates.
Note You cannot downgrade the sensor using the recovery partition. To downgrade to an earlier version, you
must install the appropriate system image file (.img file).
Use the upgrade command to upgrade the recovery partition with the most recent version so that it is
ready if you need to recover the application partition on your sensor. Recovery partition images are
generated for major and minor updates and only in rare situations for service packs or signature updates.
To upgrade the recovery partition on your sensor, follow these steps:
Step 1 Download the appropriate recovery partition image file to an FTP, SCP, HTTP, or HTTPS server that is
accessible from your sensor.
Caution Some browsers add an extension to the filename. The filename of the saved file must match what is
displayed on the download page or you cannot use it to upgrade the recovery partition.
Step 2 Log in to the CLI using an account with administrator privileges.
Step 3 Enter configuration mode.
sensor# configure terminal
Step 4 Upgrade the recovery partition.
sensor(config)#
upgrade scp://user@server_ipaddress//upgrade_path/IPS-SSP_10-K9-r-1.1-a-7.1-3-E4.pkg
sensor(config)#
upgrade ftp://user@server_ipaddress//upgrade_path/IPS-SSP_10-K9-r-1.1-a-7.1-3-E4.pkg
Step 5 Enter the server password. The upgrade process begins.
