master unit, keep the default setting, Automatically. If
you want to specify the master unit yourself, select Force
Master, then select unit 1 or 2 from the drop-down
menu.
NOTE: If unit 1 is the master unit and unit 1
becomes unavailable, unit 2 will immediately
become the master unit. If unit 1 becomes
available again within 10 minutes, unit 1 will be
restored as the master unit. If unit 1 becomes
available after 10 minutes, unit 2 will remain the
master unit. In this case, to restore unit 1 as the
master unit, set Master Election to specify unit 1
as the master unit, then reboot the stack.
