Agema NOS Initial Installation

Prerequisites

Prerequisites should be present in /var/www/html directory on DHCP server:

• All onie-installer-* files.
• The bundle file (for example: 19.1.1.431.bundle)
• The bundle version files (AS7316.ver and Z4806.ver)

Note

The bundle version file contains only line which is the version of the bundle file). For example:

$ cat AS7316.ver
19.1.1.567

How it works?

The onie-installer script installs basic Yocto Linux on “rescue” partition and boots into it. When this “rescue” Linux boots, it installs the bundle to both partition sets (A and B) and updates the GRUB menu default to partition set A.
