Rebalancing internal ports (F_Ports)

To minimize disruption that could occur once internal ports (F_Ports) go offline or when additional
external ports (N_Ports) are brought online you can modify the default behavior of the automatic
login balancing feature by disabling or enabling rebalancing of internal ports when internal port or
external port online events occur.
1. Connect to the FC SAN Module and log in using an account assigned to the admin role.
2. Enter the agautomapbalance --enable command with appropriate operands to enable
3. Enter the agautomapbalance --disable - all command with appropriate operands to disable
4. Enter the agautomapbalance --disable - all command with appropriate operands to disable
5. Enter the agautomapbalance --show command to display the automatic login redistribution
