ag 2 --pgfnmtov new_tov Displays the fabric name monitoring timeout value in seconds when used without specifying a new value. To change the current value, specify a new timeout value in seconds. The valid range is 30 to 120 seconds. The default value is 120 seconds. --failoverenable [N_Port] | -pg pgid Enables the failover policy for a given N_Port or for all N_Ports in the given port group. When failover policy is enabled for a given N_Port, F_Ports behave as follows: • If only primary F_Port to N_Port mapping is in place, all currently mapped F_Ports fail over to another available N_Port in the event the original N_Port becomes disabled. If multiple N_Ports are available for failover, F_Ports are evenly balanced across all available N_Ports. If no other N_Port is available, failover does not occur. • If preferred secondary F_Port to N_Port Mapping is in place, the F_Ports are routed through the preferred Secondary N_Port. If the preferred secondary N_Port is offline, the F_Ports are disabled. --failoverdisable [N_Port] -pg pgid Disables the failover policy for a given N_Port or for all N_Ports in the given port group. --failovershow [N_Port] If an N_Port is specified (optional), the command displays the failover policy for this N_Port. Otherwise, the failover policy for all N_Ports is displayed. Failover is displayed as enabled (1) or disabled (0). --failbackenable [N_Port] | -pg pgid Enables the failback policy for a specified N_Port or for all N_Ports in the given port group. When failback policy is enabled, ports behave as follows: • If only primary F_Port to N_Port mapping is in place, all F_Ports are automatically rerouted back to the N_Ports to which they were originally mapped as those N_Ports come back online. Only the originally mapped F_Ports fail back. In the case of multiple N_Port failures, only F_Ports that were mapped to the recovered N_Port experience failback. The remaining F_Ports are not redistributed among the online N_Ports during the failback. • If preferred secondary F_Port to N_Port mapping is in place, and the primary N_Port comes back online, then the F_Ports are rerouted through the primary N_Port. If the secondary N_Port comes online, while the primary N_Port is still offline, F_Ports are rerouted through the secondary N_Port. --failbackdisable [N_Port] | -pg pgid Disables the failback policy for the specified N_Port or for all N_Ports in the given port group. --failbackshow [N_Port] If an N_Port is specified (optional), the command displays the failback policy for this N_Port. Otherwise, the failover policy for all the N_Ports is displayed. The failback policy is displayed as disabled (0) or enabled (1). --prefset "F_Port [;F_Port2;...]" N_Port Sets the preferred secondary N_Port for one or more F_Ports. Preferred mapping is optional. Preferred F_Port to N_Port Mapping provides an alternate N_Port for F_Ports to come online for predictable failover and failback. An F_Port must have primary N_Port mapping before a secondary N_Port can be configured. The list of F_Ports to be mapped must be enclosed in double quotation marks. Port numbers must be separated by semicolons. Fabric OS Command Reference 29 53-1002746-01
