Enabling Software Auto-Update For System Software Image Synchronization - HP FlexFabric 12500 Series Configuration Manual

Enabling software auto-update for system software image
synchronization
IMPORTANT:
To ensure a successful software auto-update in a multi-user environment, prevent users from rebooting
MPUs or member devices during the software auto-update process. You can configure the information
center to output the software auto-update status to configuration terminals (see
Monitoring Configuration Guide
To synchronize software from the active MPU to the standby MPU in standalone mode, use the undo
version check ignore and version auto-update enable commands. For more information about these
commands, see Fundamentals Configuration Guide.
To synchronize software from the global active MPU to other MPUs on an IRF fabric, use the software
auto-update function in this section.
The software auto-update function propagates the software images of the global active MPU
automatically to all other MPUs in the IRF fabric.
To join an IRF fabric, an MPU must use the same software images as the global active MPU in the fabric.
When you add an MPU to the IRF fabric, software auto-update compares the startup software images of
the MPU with the current software images of the IRF global active MPU. If the two sets of images are
different, the MPU performs the following tasks automatically:
1. Downloads the current software images of the global active MPU.
2. Sets the downloaded images as the main startup software images.
3. Reboots with the new software images to rejoin the IRF fabric.
If software auto-update is disabled, you must manually update the MPU with the software images of the
global active MPU before adding the MPU to the IRF fabric.
Configuration prerequisites
Before you use the software auto-update function, verify the following items:
• The MPU you are adding to the IRF fabric is compatible with the software version running on the
global active MPU. If the software versions are not compatible, the software auto-update function
cannot correctly work.
The MPU you are adding to the IRF fabric has sufficient space for the new software images.
