Network Configuration At Management Module Failover - Hitachi Compute Blade 2000 User Manual

Network configuration at management
module failover
In a redundantly configured management module, only the management interfaces
on the active management module are enabled, and the ports on the standby
management module are closed.
If a failure occurs on the active management module, the standby management
module takes over and continues operation. The ports on the newly active
management module are opened, and its management interfaces are enabled.
The newly active management module uses the same IP addresses for the
management interfaces as did the failed-over management module.
When connecting to a management interface, you do not need to be aware of which
management module is active.
