System and method for group-policy-based configuration
A system includes a processor of a first controller of an information handling system. The processor is operable to determine that a change has occurred in a first group, the first group comprising a plurality of nodes governed by a group policy, and in response to determining that a change has occurred in the first group, identify one or more of the plurality of nodes to notify, wherein the one or more nodes are identified based on subscription information stored in a data structure. The processor is further operable to broadcast, by the controller, a notification to each the identified nodes, the notification including information about the change in the first group, and wherein one or more of the identified nodes updates itself based on information included in the change notification and on content of the group policy.
1. A method comprising:
in response to receiving a request to receive information about a first group from a first node, storing, by a controller, an association of the first node and the first group in a data structure, wherein:
the first group comprises a plurality of nodes governed by a group policy; and
the data structure comprises one or more associations of the plurality of nodes;
in response to determining that a change has occurred in the first group, identifying, by the controller, one or more of the plurality of nodes to notify, wherein the one or more nodes are identified based on the associations stored in the data structure; and
broadcasting, by the controller, a notification to each of the identified nodes, the notification including information about the change in the first group;
wherein:
one or more of the identified nodes updates itself based on information included in the change notification and on content of the group policy; and
determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from a chassis management controller, a notification that the change has occurred, wherein the chassis management controller is configured to detect a change in one or more nodes of a chassis.
2. The method of claim 1 , further comprising:
adding, by a controller, a second node to the first group.
3. The method of claim 2 , wherein the second node is added to the first group in response to the first node being introduced to a first chassis of an information handling system.
4. The method of claim 1 , wherein:
the change comprises an update to a configuration of at least one node of the plurality of nodes; and
the notification further includes configuration information of each node of the plurality of nodes.
5. The method of claim 1 , wherein the change comprises one or more of:
an addition of a node to the first group;
a removal of a node from the first group;
a replacement of a node in the first group;
an update to firmware of a node in the first group; and
an update to a configuration of a node in the first group.
6. The method of claim 1 , wherein determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from at least one of the plurality of nodes, a notification that the change has occurred.
7. A system comprising a processor of a first controller of an information handling system, the processor operable to:
store, in response to receiving a request to receive information about a first group from a first node, an association of the first node and the first group in a data structure, wherein:
the first group comprises a plurality of nodes governed by a group policy; and
the data structure comprises one or more associations of the plurality of nodes;
in response to determining that a change has occurred in the first group, identify one or more of the plurality of nodes to notify, wherein the one or more nodes are identified based on the associations stored in the data structure; and
broadcast, by the controller, a notification to each the identified nodes, the notification including information about the change in the first group;
wherein:
one or more of the identified nodes updates itself based on information included in the change notification and on content of the group policy; and
determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from a chassis management controller, a notification that the change has occurred, wherein the chassis management controller is configured to detect a change in one or more nodes of a chassis.
8. The system of claim 7 , the processor further
operable to:
add a second node to the first group.
9. The method of claim 8 , wherein the second node is added to the first group in response to the first node being introduced to a first chassis of an information handling system.
10. The system of claim 7 , wherein:
the change comprises an update to a configuration of at least one node of the plurality of nodes; and
the notification further includes configuration information of each node of the plurality of nodes.
11. The system of claim 7 , wherein the change comprises one or more of:
an addition of a node to the first group;
a removal of a node from the first group;
a replacement of a node in the first group;
an update to firmware of a node in the first group; and
an update to a configuration of a node in the first group.
12. The system of claim 7 , wherein determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from at least one of the plurality of nodes, a notification that the change has occurred.
13. A non-transitory computer readable storage medium comprising instructions, the instructions, when executed by a processor, executable to:
store, in response to receiving a request to receive information about a first group from a first node, an association of the first node and the first group in a data structure, wherein:
the first group comprises a plurality of nodes governed by a group policy; and
the data structure comprises one or more associations of the plurality of nodes;
in response to determining that a change has occurred in the first group, identify one or more of the plurality of nodes to notify, wherein the one or more nodes are identified based on the associations stored in the data structure; and
broadcast, by the controller, a notification to each the identified nodes, the notification including information about the change in the first group;
wherein:
one or more of the identified nodes updates itself based on information included in the change notification and on content of the group policy; and
determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from a chassis management controller, a notification that the change has occurred, wherein the chassis management controller is configured to detect a change in one or more nodes of a chassis.
14. The non-transitory computer readable storage medium of claim 13 , wherein the instructions are further executable to:
add a second node to the first group.
15. The non-transitory computer readable storage medium of claim 13 , wherein:
the change comprises an update to a configuration of at least one node of the plurality of nodes; and
the notification further includes configuration information of each node of the plurality of nodes.
16. The non-transitory computer readable storage medium of claim 13 , wherein the change comprises one or more of:
an addition of a node to the first group;
a removal of a node from the first group;
a replacement of a node in the first group;
an update to firmware of a node in the first group; and
an update to a configuration of a node in the first group.
17. The non-transitory computer readable storage medium of claim 13 , wherein determining that a change has occurred in at least one of the plurality of nodes comprises receiving, from at least one of the plurality of nodes, a notification that the change has occurred.
