Performing a Recovery Installation Using an Emergency Boot Device
If Junos OS on your device is damaged in some way that prevents the software from loading correctly,
you might need to perform a recovery installation using an emergency boot device (for example, a USB
flash drive) to restore the default factory installation. After you have recovered the software, you need to
restore the device configuration. You can either create a new configuration as you did when the device
was shipped from the factory, or if you saved the previous configuration, you can simply restore that file
to the device.
We recommend that you perform the following steps before you perform the recovery installation:
1. Ensure that you have an emergency boot device to use during the installation. See
Emergency Boot Device” on page 245
for information about how to create an emergency boot device.
2. Copy the existing configuration in the file /config/juniper.conf.gz from the device to a remote system,
such as a server, or to an emergency boot device. For extra safety, you can also copy the backup
configurations (the files named /config/juniper.conf.n, where n is a number from 0 through 9) to a
remote system or to an emergency boot device.
You can use the system snapshot feature to complete this step. The system snapshot feature takes a
“snapshot” of the files currently used to run the MX10008 router—the complete contents of the /config
and /var directories, which include the running Juniper Networks Junos OS, the active configuration,
and the rescue configuration—and copies all of these files into a memory source.
WARNING:
The recovery installation process completely overwrites the entire
contents of the internal flash storage.
3. Copy any other stored files to a remote system as desired.
To reinstall Junos OS:
1. Insert the emergency boot device into the router.
2. Power cycle the router.
The emergency boot device is detected. At this time, you can load Junos OS from the emergency boot
device onto the internal flash storage.
