Recover an IRF fabric in recovery
state
mad restore Required
NOTE:
For a switch that transitioned to recovery state due to the multi-active collision, if you need to bring up one
of its port that are already shut down, HP recommends that you execute the mad restore command to
recover the switch and make it operate in the active state instead of executing the undo shutdown
command to perform a manual recovery.
IRF configuration fast recovery
If a member switch has only one MPU and that board is corrupted, use the following fast recover function
to avoid complicated IRF configuration.
Configuration prerequisites
• HP recommends that you perform the fast recovery operation when the switch operates in IRF mode.
• Save the IRF configuration file on all MPUs of the IRF fabric. Assume the name of the configuration
file is a.cfg.
