Management and Configuration Guide K/KA/KB.15.15

The redundancy management-module command shows Nonstop switching redundant
management being enabled. The show redundancy command displays “Mgmt Redundancy”
as Nonstop switching enabled. Management Module 1 (MM1) is the standby management module
and Management Module 2 (MM2) is the active management module.
Example
Enabling non-stop switching redundancy.
(HP_Switch_name#) redundancy management-module nonstop-switching
All configuration files and software images on the off-line management module
will be overwritten with the data from the current active management module.
During initial syncing from active to standby management module configuration
changes are disallowed. Do you want to continue [y/n]? y

The no version of the redundancy management-module command is used to disable management
module redundancy on the switch, as seen in Figure 7-4. The show redundancy command displays
“Mgmt Redundancy” as Nonstop switching disabled. The standby management module in slot
MM1 is now offline. The management module in slot MM2 remains the active management module.
NOTE: HP recommends that you leave management module redundancy enabled. If the active
management module has a hardware failure, the standby module may take over and may have
an old configuration since file synchronization has not occurred when management module
redundancy was disabled.
The no redundancy management-module command allows you to shut down a management
module that is not functioning correctly without physically removing the module. If you want to
remove the module, first perform the shutdown procedure as explained in “Hotswapping Out the
Active Management Module” on page 7-25, and then remove the module.
Example
Disabling redundancy:
(HP_Switch_name#) no redundancy management-module
The other management module may reboot and it will no longer be used for system
redundancy except in the case of a hardware failure of the active management
module. Do you want to continue[y/n]? y
(HP_Switch_name#) show redundancy
