Abstract

One or more chassis management controllers may be configured to receive a user indication of a user desire to physically remove a modular information handling resource from a chassis, determine whether the modular information handling resource is shared or nonshared with respect to modular information handling systems present in the chassis, determine whether the modular information handling systems associated with the modular information handling resource are powered on, receive at least one response to one query to the user regarding at least one user preference regarding removal of the modular information handling resource, and determine if the information handling resource may be safely removed based at least on: the determinations of whether the information handling system resource is shared or nonshared and whether the modular information handling systems present in the chassis and associated with the modular information handling resource are powered on, and the at least one response.

Claims (48)

1. A system comprising:

a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources; and

one or more chassis management controllers housed in the chassis and configured to:

in response to a request to remove a modular information handling resource from the chassis, determine whether the modular information handling resource is shared or nonshared with respect to modular information handling systems present in the chassis; and

determine if the information handling resource may be safely removed from the chassis based at least on the determination of whether the information handling system resource is shared or nonshared.

2. A system according to claim 1 , the one or more chassis management controllers configured to store configuration information regarding the modular information handling resource prior to removal.

3. A system according to claim 1 , the one or more chassis management controllers further configured to communicate a hot plug event to modular information handling systems present in the chassis and associated with the modular information handling resource in response to an indication of a user desire to remove associations between the modular information handling resource and the modular information handling systems.

4. A system according to claim 3 , the one or more chassis management controllers further configured to communicate a message to the user to ensure that the modular information handling systems received the hot plug event.

5. A system according to claim 1 , the one or more chassis management controllers further configured to power down the information handling resource in response to determining that the information handling resource may be safely removed from the chassis.

6. A system according to claim 1 , the modular information handling resource configured to generate a physical indication of the physical location of the information handling resource to be removed in response to a determination by the one or more chassis management controllers that the information handling resource may be safely removed from the chassis.

7. A system according to claim 1 , further comprising a plurality of slots, each slot for coupling a respective modular information handling resource to the chassis and configured to generate a physical location of the information handling resource to be removed in response to a determination by the one or more chassis management controllers that the information handling resource may be safely removed from the chassis.

8. A system according to claim 1 , the one or more chassis management controllers further configured to communicate a message to the user that it is safe to physically remove the information handling resource in response to determining that the information handling resource may be safely removed from the chassis.

9. A system according to claim 1 , wherein the one or more chassis management controllers are further configured to:

determine whether the modular information handling systems present in the chassis and associated with the modular information handling resource are powered on; and

further determine if the information handling resource may be safely removed from the chassis based at least on a determination of whether the modular information handling systems present in the chassis and associated with the modular information handling resource are powered on.

10. A system according to claim 1 , wherein the one or more chassis management controllers are further configured to:

receive at least one response to one query to A user regarding at least one user preference regarding removal of the modular information handling resource; and

further determine if the information handling resource may be safely removed from the chassis based at least on the at least one response.

11. A system according to claim 10 , the at least one response indicative of at least one of:

a user desire regarding whether to power down modular information handling systems present in the chassis and associated with the modular information handling resource;

a user desire regarding whether to remove associations between the modular information handling resource and the modular information handling systems present in the chassis and associated with the modular information handling resource; and

a user desire to remove the modular information handling resource despite warnings regarding removal of the modular information handling resource.

12. A system according to claim 10 , the at least one response received from at least one of:

a keyboard-video-mouse interface; and

a user interface.

13. A method comprising, in response to receiving a request to remove a modular information handling resource from a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources:

determining whether the modular information handling resource is shared or nonshared with respect to modular information handling systems present in the chassis; and

determining if the information handling resource may be safely removed from the chassis based at least on the determination of whether the information handling system resource is shared or nonshared.

14. A method according to claim 13 , further comprising storing configuration information regarding the modular information handling resource prior to removal.

15. A method according to claim 13 , further comprising communicating a hot plug event to modular information handling systems present in the chassis and associated with the modular information handling resource in response to an indication of a user desire to remove associations between the modular information handling resource and the modular information handling systems.
