Because a management module failure results in a configuration
loss, it is best practice to install a standby management module when
using IFM.
The
IFM configuration
is not included in the management module configuration backup. Such
a backup would allow
IFM configuration
updates from a file that might be outdated. This would cause inconsistencies
with the configuration of other chassis.
The
IFM configuration
is chassis-based and does not transfer with the physical management
module. When a management module is moved to a new chassis, it clears
out its
IFM configuration,
and the
IFM configuration
must be reapplied on the new management module.
Note: When a management
module is moved to a new chassis, it clears the configuration for
all bays except for bays that have servers powered-on with a valid IFM configuration
that is already in use. For these bays, the management module uses
the IFM configuration
as defined on the servers.
If the management module configuration
is reset to factory defaults, the IFM configuration
is handled as if a new management module was installed in the chassis.
If
the primary management module fails, the standby management module
contains the
IFM configuration
and takes over.
Note: You might have to wait approximately
2 minutes while the active management module transfers firmware and
configuration information to the standby management module.
