If the AP has been online on the main AC, and then add AP information offline on the standby AC, the AP status on the standby AC will be displayed as fault. In this case, you need to execute the undo hsb enable command in the HSB backup group view of the standby AC to disable the HSB active/standby backup function, and then execute the hsb enable command to enable the HSB active/standby backup function. At this time, the information on the active AC will be backed up to Standby AC, to achieve consistent backup of active and standby information, and the status of the AP on the AC will be displayed as standby.
