The following sections explain how the options work.
Store Before Load
The “Store Device Configurations Before Load” option captures the device
configuration before loading it and then saves it if the load fails.
This option compares the backed up configuration with the one that you
subsequently loaded to the device. If the backed up configuration differs from
the subsequently loaded one, ECM saves the backed up configuration. This
ensures that you always have the original configuration to work with if the
load fails. If the load succeeds, the backed up configuration and the one on the
device are the same. In this case, ECM does not save the backed up one so that
you do not unnecessarily have two copies of the same configuration.
When you perform a load with the “Store Device Configuration Before Load”
option on and the load fails, ECM saves the original device configuration
before the load, giving it the same name as the configuration you were trying
to load but with an increment in the version number.
For example, if you tried to load (but did not totally succeed) a configuration
called First_shift version 1 to a device, you will see the following
configurations listed in the Main and Configurations windows:
First_shift version 1
First_shift version 2
First_shift version 1 is the configuration that you were trying to load to the
device and is now partially loaded to the device. First_shift version 2 is the
device configuration that ECM stored because the “Store Device Configuration
Before Load” option was on. Version 2 is the complete original configuration.
Safe Load
The ECM Safe Load option provides you with a way to control the load
process.
When the Safe Load option is on, ECM captures the configuration of the
device and then begins loading one attribute at a time. If ECM cannot load an
attribute, it stops the load process and attempts to roll back the original
configuration to the device. If it cannot roll back the configuration, ECM
notifies you so you can manually restore the configuration.
