Hitless management on the FSX 800 and FSX 1600
3
NOTE
Hitless OS upgrade is not impacted by this option and is supported whether or not hitless failover is
enabled.
NOTE
Synchronization between the active management module and standby management module will
occur whether or not hitless failover is enabled.
To enable hitless failover, enter the following command at the Global CONFIG level of the CLI:
Brocade(config)#hitless-failover enable
The command takes effect immediately. Manual switchover is allowed, and in the event of a
failover, the standby management module will take over the active role without reloading the
system.
Syntax: [no] hitless-failover enable
Use the no form of the command to disable hitless failover once it has been enabled.
Executing a hitless switchover on the FSX 800 and
FSX 1600
Hitless failover must be enabled before a hitless switchover can be executed. To enable hitless
failover, refer to “Enabling hitless failover on the FSX 800 and FSX 1600” on page 105.
To switch over to the standby module (and thus make it the active module), enter the following
command.
Brocade# switch-over-active-role
Once you enter this command, the system will prompt you as follows.
Are you sure? (enter ’y’ or ’n’): y
Running Config data has been changed. Do you want to continue
the switch-over without saving the running config? (enter ’y’ or ’n’): n
Please save the running config and try switch-over again
Syntax: switch-over-active role
If this command is entered when hitless failover is disabled, the following message will appear on
the console:
Switch-over is not allowed. Reason: hitless-failover not configured.
A management slot which is in active management preference will always attempt to be active on
the next reboot.
To reset the preference, enter the command such as the following:
Brocade(config)# set-active-mgmt mgmt0/mgmt1
Syntax: set-active-management management slot numbers
NOTE
The default active management preference is set to mgmt0 (slot 9).
