System and method for policy based management of a communication device configuration persistence
View Patent ↗An information handling system includes a communication device and a service processor. The communication device includes a first terminal, and a second terminal to communicate with a network storage array. The service processor includes a first terminal to receive persistence policy for the communication device. The service processor is configured to detect a reset of the information handling system, to determine a type of reset performed in an information handling system, to evaluate the persistence policy with respect to the type of reset during a power-on self test executed in the information handling system after the information handling system, and to configure, via the first terminal of the communication device, the attributes of the communication device based on the persistence policy and the type of reset.
