R21xx-HP FlexFabric 11900 IRF Command Reference

10
Before enabling software auto-update, 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, and you must
reboot the device and access the Boot menu to delete files.
When you add a device to the IRF fabric, the software auto-update function compares the startup
software images of the joining device with the current software images of the IRF master. If the two sets
of images are different, the device automatically downloads the current software images of the master,
sets the downloaded images as its main startup software images, and automatically reboots with the
new software images to rejoin the IRF fabric.
If the device you are adding to the IRF fabric is incompatible with the software version running on the
master, the software auto-update function cannot work.
If software auto-update is disabled, you must manually update the device with the software images of the
master before adding it to the IRF fabric.

Usage guidelines
This command is available in IRF mode. Changing the operating mode from IRF to standalone can cause
loss of the IRF domain setting even if you have saved the configuration.
One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and prevent
IRF fabrics from interfering with one another.
If you use a member in one IRF fabric as the intermediate device for performing LACP MAD for another
IRF fabric, assign the two IRF fabrics different domain IDs to avoid false detection of IRF split.
