Management module redundancy configuration

Management module redundancy configuration
Configuring management module redundancy consists of performing one optional task (changing
the default active chassis slot) as described in the following section.
Changing the default active chassis slot
By default, the Brocade system considers the module installed in slot M1 to be the active
management module. However, you can change the default active chassis slot to M2 using the
active-management command.
The active-management command determines which management module will become active
after a power cycle. By default, the top management module of the Brocade XMR 16000 and
Brocade MLX-16 or the left management module of the Brocade XMR 4000, Brocade XMR 8000,
Brocade MLX-4 and Brocade MLX-8 become active after a power cycle. This information is stored in
the chassis’s backplane EPROM and not in the configuration file.
To change the default active chassis slot from the default state of M1 to M2, enter the following
commands.
Brocade(config)# redundancy
Brocade(config-redundancy)# active-management mgmt-2
Syntax: active-management mgt-module
The mgt-module parameter specifies the management module, either mgmt-1 or mgmt-2.
NOTE
This configuration has no effect on the reload and boot commands. it only applies to the power cycle
when both management modules are installed in a chassis.
Managing management module redundancy
You can perform the following management tasks related to management module redundancy for
Brocade devices:
• Perform immediate synchronization of files
• Perform a manual switchover to the standby module
• Reboot the standby module
File synchronization between active and standby
management modules
Each active and standby management module contains the following files that can be synchronized
between the two modules:
• Flash code – The flash code can include the following files:
• monitor, which contains the Real Time Operating System (RTOS) for the management
module
• primary, which contains the primary Multi-Service IronWare image for the management
module
