This example formats the NAND Flash device and installs the new Junos OS image on
the media with dual-root partitioning. Install the Junos OS Release 12.2 or later image
from the CLI by using the request system software add
automatically created on ACX Series routers and no option needs to be manually entered
for creating partitions. This command copies the image to the device, and then reboots
the device for installation. The device boots with the Release 12.2 or later image installed
with the dual-root partitioning scheme. The formatting and installation process is
scheduled to run on the next reboot. Therefore, we recommend that this option be used
together with the reboot option.
NOTE: The process might take 15 to 20 minutes. The system is not accessible
over the network during this time.
WARNING: Using the
existing contents of the media. Only the current configuration is preserved.
You should back up any important data before starting the process.
NOTE: Dual, internal NAND Flash device (first daOs1, then daOs2) and USB
storage device are the storage media available on the ACX Series router. The
USB storage device is not dual-root partitioned.
In this example, add the software package junos-juniper-12.2R1.9-domestic.tgz with the
following options:
option to install the software package. However, do not save the copies of
no-copy
the package files. You should include this option if you do not have enough space on
the internal media to perform an upgrade that keeps a copy of the package on the
device.
no-validate option to bypass the compatibility check with the current configuration
before installation starts.
option to reboot the device after installation is completed.
reboot
