how to f5 or load balancer os upgrade | BIG IP iso upload & installation
F5 BIG IP iso upload & installation,
There are several types of installation and upgrade options for F5OS software:
Rolling upgrade
Out-of-service system upgrade
Clean (or bare metal) installation
Rolling upgrade
A rolling upgrade installs new F5OS version 1.2.0 or later software on one system controller or blade in a chassis partition at a time, without an interruption to system controller availability.
If your VELOS system is running F5OS-C software version 1.2.0, F5 strongly recommends that you upgrade to F5OS-C version 1.2.1 or later.
If your VELOS system is running F5OS-C software version 1.1.3 or earlier, you must first upgrade to F5OS-C version 1.1.4 before you can install version 1.2.1 or later.
This method preserves old image and configuration data, and includes these three sub-types:
ISO upgrade
Upgrades both the operating system (os) and services for system controllers or chassis partitions.
Partial upgrade
Upgrades os or services for system controllers or partitions only. The partial update os file has a .os extension and service file has a .img extension. You import partial upgrade files by using either the file import
command or by logging in as a root user and using SCP to copy files to the active system controller at the images/import/os
or images/import/services
directories respectively.
Patch upgrade
Upgrades or patches a subset of system controller or partition services. The patch file has a .patch extension. You import patch upgrade files by using either the file import
command or by using SCP to copy files to the active system controller at the images/import/services
directory.
Out-of-service system upgrade
An out-of-service system upgrade installs new software on both system controllers or all blades in a chassis partition and results in a service outage.
This was the default upgrade method for software versions prior to F5OS version 1.2.0. It preserves old image and configuration data, and includes these three sub-types:
ISO upgrade
Upgrades both the operating system (os) and services for system controllers or chassis partitions.
Partial upgrade
Upgrades os or services for system controllers or partitions only. The partial update os file has a .os extension and service file has a .img extension. You import partial upgrade files by using either the system import
