Irf Domain - HP FlexFabric 7900 Series Command Reference Manual

Usage guidelines
This command is available in IRF mode. When you change the operating mode from IRF to standalone,
the command configuration is lost, regardless of whether you have saved the configuration.
To join an IRF fabric, a device must use the same software images as the master in the IRF 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 performs the following tasks automatically:
1. Downloads the current software images of the master.
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 device with the software images of
the master before adding it to the IRF fabric.
Before you use the software auto-update function, verify the following items:
• The device you are adding to the IRF fabric is compatible with the software version running on the
master. If the software versions are incompatible, the software auto-update function cannot work.
The storage space of the device you are adding to the IRF fabric is sufficient for saving the new
•
software images.
If the device does not have enough storage space, it deletes the current software images automatically.
If the reclaimed space is still insufficient, the device cannot complete the auto-update. You must reboot
the device and access the BootWare menus to delete files.
To ensure a successful software auto-update in a multi-user environment, prevent users from rebooting or
swapping 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 Network Management
and Monitoring Configuration Guide).
