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.
Disables the failover policy for a given N_Port or for all N_Ports in the given port
group.
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).
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.
Disables the failback policy for the specified N_Port or for all N_Ports in the given
port group.
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).
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.
Deletes the preferred Secondary N_Port for the specified F_Ports. The list of
F_Ports to be deleted from the secondary mapping must be enclosed in double
quotation marks. Port numbers must be separated by semicolons.
Displays the preferred Secondary N_Port for all F_Ports.
