HP 6125G Command Reference Manual page 127

In an IRF fabric, use the undo startup saved-configuration command with caution. This command can
cause an IRF split after the IRF fabric or an IRF member reboots.
If neither backup nor main is specified, the startup saved-configuration command specifies the main
next-startup configuration file.
For high availability, specify separate files as the main and backup next-startup configuration files, even
though they can be the same file.
The undo startup saved-configuration command changes the file attribute of the main and backup
next-startup configuration files to NULL, but does not delete the two configuration files.
You can also specify a configuration file as a next-startup configuration file when you use the save
command to save the running configuration to it.
Related commands: display startup.
