This document helps to boot NCS5500 series router through USB devices. This very useful for customers installing the routers where they don’t have access to install framework nor to have complicated install procedure. Please follow the steps defined in the document step-by-step to achieve the USB boot on NCS5500 devices.
GISO is a customised iso (iso 9660 file system), which includes desired version of iso + rpms + SMUs + router config + autorun scripts [6.5.3]for making image management easy
Compared to TAR format, iso has native support in Linux for boot/installation process, eg. bundling device config within an ISO
RPMs and bug fixes can be delivered via GISO format helps to simplify during install process
GISO is a single file with FCS image or image with bug fixes
A Linux machine meets following requirements
'mount','rm','cp','umount','zcat','chroot','mkisofs' tools should be available
User should have privilege to execute all of the above linux tool/cmd
Minimum python version 2.7
system should have at least 4 GB free disk space
py script (available on all eXR running routers in the location: /pkg/bin/gisobuild.py)
mini iso is mandatory on file system [mandatory]
Desired rpms to build GISO [mandatory]

Right (rx) permissions for the rpms and the other files
Note: Kernel version of the system should be greater than 3.16 or greater than the version of kernel of cisco iso because of the initrd.img file creation during gisobuild process
2. How to add custom files or rpms to spcified location using GISO?
create a directory on USB disk named “other-rpms” and put a few files in it. And then create a script “test.sh” with the below content into the GISO. After USB boot, the script copied the files from USB other-rpm directory to /harddisk:/additional_rpms directory.
