Enabling software auto-update for software image
synchronization
IMPORTANT:
To ensure a successful software auto-update in a multi-user environment, prevent anyone from rebooting
or replacing member devices during the auto-update process. To inform administrators of the auto-update
status, configure the information center to output the status message to configuration terminals (see
Network Management and Monitoring Configuration Guide).
The software auto-update feature automatically synchronizes the current software images of the master to
devices that are attempting to join the IRF fabric.
To join an IRF fabric, a device must use the same software images as the master in the fabric.
When you add a device to the IRF fabric, software auto-update compares the startup software images of
the device with the current software images of the IRF master. If the two sets of images are different, the
device automatically performs the following tasks:
1. Downloads the current software images of the master.
2. Sets the downloaded images as its main startup software images.
3. Reboots with the new software images to rejoin the IRF fabric.
You must manually update the new device with the software images running on the IRF fabric in the
following situations:
• Software auto-update is disabled.
• Software auto-update fails to update software. This situation might occur if the IRF fabric cannot
identify the software version used on the new device.
Configuration prerequisites
Make sure the device you are adding to the IRF fabric has sufficient storage space for the new software
images.
If sufficient storage space is not available, the device automatically deletes the current software images.
If the reclaimed space is still insufficient, the device cannot complete the auto-update. You must reboot the
device, and then access the Boot menu to delete files.
