Abstract

A system and method for updating software in an information handling system are disclosed. One or more relationships between a firmware package and a set of components associated with the information handling system are generated. A first storage partition identifier is generated based, at least in part, on the relationships. A second storage partition identifier generate is based, at least in part, on one or more parameters of the set of components, where the second storage partition identifier is associated with the first storage partition identifier. A first storage partition having the first storage partition identifier is generated. A second storage partition having the second storage partition identifier is generated. A copy of the firmware information is stored so that the firmware information is associated with the second storage partition. Firmware for at least one of the set of components is modified based, at least in part, on firmware information.

storing a copy of the updated firmware information on the computer readable medium so that the updated firmware information is associated with the second storage partition; and

modifying firmware for at least one of the second set of components based, at least in part, on the updated firmware information.

2. The method of claim 1, wherein the method further comprises:

receiving a third firmware package;

identifying the third firmware package to use for rollback of firmware for a target component; and

determining whether the target component relates to a previously generated storage partition identifier.

3. The method of claim 2, wherein the target component relates to the second storage partition identifier.

4. The method of claim 3, wherein the method further comprises:

deleting the third storage partition identifier;

associating the second storage partition identifier with the first storage partition identifier; and

modifying firmware for at the target component based, at least in part, on the firmware information associated with the second storage partition identifier.

5. A non-transitory, computer readable storage medium comprising executable instructions to cause at least one processor coupled to the computer readable storage medium to:

determine one or more relationships between a firmware package and a set of components in the information handling system, wherein the firmware package comprises firmware information for the set of components;

generate a first storage partition identifier based, at least in part, on the one or more relationships;
