Recovering the Application Partition

You can recover the application partition image for the sensor if it becomes unusable. Some network

configuration information is retained when you use this method, which lets you have network access

after the recovery is performed. Use the recover application-partition command to boot to the recovery

partition, which automatically recovers the application partition on your sensor. If you have upgraded

your recovery partition to the most recent version before you recover the application partition image,

you can install the most up-to-date software image.

Because you can execute the recover application-partition command through a Telnet or SSH

connection, we recommend using this command to recover sensors that are installed at remote locations.

Note When you reconnect to the sensor after recovery, you must log in with the default username and

password cisco.

Recovering the Application Partition Image

To recover the application partition image, follow these steps:

Step 1 Download the recovery partition image file to an FTP, HTTP, or HTTPS server that is accessible from

your sensor.

Step 2 Log in to the CLI using an account with administrator privileges.

Step 3 Enter configuration mode.

sensor# configure terminal

Note To upgrade the recovery partition the sensor must already be running IPS 7.1(3)E4.

Step 4 Recover the application partition image.

sensor(config)# recover application-partition

Warning: Executing this command will stop all applications and re-image the node to

version 7.1(2)E4. All configuration changes except for network settings will be reset to

default.

Continue with recovery? []:

Step 5 Enter yes to continue. Shutdown begins immediately after you execute the recover command. Shutdown

can take a while, and you will still have access to the CLI, but access will be terminated without warning.

The application partition is reimaged using the image stored on the recovery partition. You must now

initialize the sensor with the setup command.The IP address, netmask, access lists, time zone, and offset

are saved and applied to the reimaged application partition. If you executed the recover

application-partition command remotely, you can SSH to the sensor with the default username and

password (cisco/cisco) and then initialize the sensor again with the setup command. You cannot use

Telnet until you initialize the sensor because Telnet is disabled by default.
