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.

2. The information handling system of claim 1 further comprising:
a basic input/output system including a first terminal, the basic input/output system to provide a handshake signal to the service processor during the power-on self test, to stall the power-on self test in response to the handshake signal being provided, to receive a response handshake from the service processor in response to the attributes of the communication device being configured based on the persistence policy and the type of reset, and to provide an initialization signal to initialize the communication device in response to the response handshake.
3. The information handling system of claim 1 wherein the type of reset is selected from a group consisting of an alternating current power loss, a cold reset, and a warm reset.
4. The information handling system of claim 3 wherein the cold reset includes a main power bus of the information handling system being powered down, power in an auxiliary power device of the information handling system being maintained while the main power bus powered down, and the main power bus being powered back up.
5. The information handling system of claim 3 wherein the warm reset includes a peripheral component interconnect (PCI) reset being performed, power in an auxiliary power device of the information handling system being maintained, and power on a main power bus of the information handling system being maintained.
6. The information handling system of claim 1 wherein the persistence policy for the attributes of the communication device varies based on the type of reset.
7. The information handling system of claim 1 wherein the communication device is selected from a group consisting of a network interface card, a converged network adapter, and a hub bus adapter.
8. A method comprising:
detecting a reset of an information handling system;
evaluating a persistence policy for attributes of a communication device with respect to a type of reset performed in the information handling system during a power-on self test executed in the information handling system after the information handling system is reset; and

9. The method of claim 8 wherein the type of reset is selected from a group consisting of an alternating current power loss, a cold reset, and a warm reset.
10. The method of claim 9 wherein resetting the information handling system with the cold reset comprises:
powering down a main power bus of the information handling system;
maintaining power in an auxiliary power device of the information handling system while the main power bus powered down; and
powering up the main power bus.
11. The method of claim 9 wherein resetting the information handling system with the warm reset comprises:
performing a peripheral component interconnect (PCI) reset;
maintaining power in an auxiliary power device of the information handling system; and
maintaining power on a main power bus of the information handling system.
12. The method of claim 8 wherein the persistence policy for the attributes of the communication device varies based on the type of reset.
13. The method of claim 8 wherein the communication device is selected from a group consisting of a network interface card, a converged network adapter, and a hub bus adapter.
14. The method of claim 8 further comprising:
providing a handshake signal to the service processor during the power-on self test;
stalling the power-on self test in response to providing the handshake signal;
providing a response handshake in response to the attributes of the communication device being configured based on the persistence policy and the type of reset;
providing an initialization signal to initialize the communication device in response to the response handshake.
15. A non-transitory computer readable medium including code for performing a method, the method comprising:
detecting a reset of an information handling system;
