System and method for managing a power supply management namespace during a chassis boot up
A method for managing a chassis includes obtaining, by an enclosure controller of the chassis, a power supply application to the chassis using a power supply interface, wherein the power supply interface is operatively connected to a plurality of power supplies, initiating a boot-up of a kernel of the chassis in response to the power supply application, initiating a parallel boot task using the power supply management temporary namespace to identify a power supply of the plurality of power supplies, initiating a mounting of a boot-up file system, and initiating a user space boot-up using the boot-up file system, wherein the user space boot-up and the parallel boot task are initiated in parallel.
1. A chassis, comprising:

a processor operating in the enclosure controller,
wherein the enclosure controller is adapted to:
apply power to the enclosure controller using the power supply interface;
initiate a boot-up of a kernel of the chassis in response to the applying power;
initiate a parallel boot task using a parallel temporary namespace to identify a power supply of the plurality of power supplies,
wherein initiating the parallel boot task comprises synchronizing a real-time clock of a user space and an internal timer of the enclosure controller;
initiate a mounting of a boot-up file system; and
initiate a user space boot-up using the boot-up file system, wherein the user space boot-up and the parallel boot task are initiated in parallel.
2. The chassis of claim 1 , wherein initiating the parallel boot task comprises:
identifying, using the parallel temporary namespace, the plurality of power supplies;
performing a power supply analysis using the parallel temporary namespace to determine a power supply selection, wherein the power supply selection specifies the power supply; and
initiating the power supply management for the chassis using the power supply selection.
3. The chassis of claim 2 , wherein initiating the power supply management comprises powering on the power supply using the power supply selection.
4. The chassis of claim 1 , further comprising:
a light emitting device,
wherein the parallel boot task further comprises:
prompting the light emitting device to display a first light pattern.
5. The chassis of claim 4 , wherein the enclosure controller is further programmed to:
after completion of the user space boot-up, prompting the light emitting device to display a second light pattern.
6. The chassis of claim 1 , wherein apply power to the enclosure controller comprises obtaining the power from a second power supply of the plurality of power supplies.
7. A method for managing a chassis, comprising:
applying, by an enclosure controller of the chassis, a power to the enclosure controller using a power supply interface, wherein the power supply interface is operatively connected to a plurality of power supplies;
initiating a boot-up of a kernel of the chassis in response to the applying power;
initiating a parallel boot task using a parallel temporary namespace to identify a power supply of the plurality of power supplies,
wherein initiating the parallel boot task comprises synchronizing a real-time clock of a user space and an internal timer of the enclosure controller;
initiating a mounting of a boot-up file system; and
initiating a user space boot-up using the boot-up file system, wherein the user space boot-up and the parallel boot task are initiated in parallel.
8. The method of claim 7 , wherein initiating the parallel boot task comprises:
identifying, using the parallel temporary namespace, the plurality of power supplies;
performing a power supply analysis using the parallel temporary namespace to determine a power supply selection, wherein the power supply selection specifies the power supply; and
initiating the power supply management for the chassis using the power supply selection.
9. The method of claim 8 , wherein initiating the power supply management comprises powering on the power supply using the power supply selection.
10. The method of claim 7 , wherein the parallel boot task further comprises:
prompting a light emitting device to display a first light pattern.
11. The method of claim 10 , further comprising:
after completion of the user space boot-up, prompting the light emitting device to display a second light pattern.
12. The method of claim 7 , wherein applying the power comprises obtaining the power from a second power supply of the plurality of power supplies.
13. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing a chassis of an information handling system, the method comprising:
applying, by an enclosure controller of the chassis, power to the enclosure controller using a power supply interface, wherein the power supply interface is operatively connected to a plurality of power supplies;
initiating a boot-up of a kernel of the chassis in response to the power supply application;
initiating a parallel boot task using a parallel temporary namespace to identify a power supply of the plurality of power supplies,
wherein initiating the parallel boot task comprises synchronizing a real-time clock of a user space and an internal timer of the enclosure controller;
initiating a mounting of a boot-up file system; and
initiating a user space boot-up using the boot-up file system, wherein the user space boot-up and the parallel boot task are initiated in parallel.
14. The non-transitory computer readable medium of claim 13 , wherein initiating the parallel boot task comprises:
identifying, using the parallel temporary namespace, the plurality of power supplies;
performing a power supply analysis using the parallel temporary namespace to determine a power supply selection, wherein the power supply selection specifies the power supply; and
initiating the power supply management for the chassis using the power supply selection.
15. The non-transitory computer readable medium of claim 14 , wherein initiating the power supply management comprises powering on the power supply using the power supply selection.
16. The non-transitory computer readable medium of claim 13 , wherein the parallel boot task comprises:
after initiating the user space boot-up, prompting a light emitting device to display a first light pattern.
17. The non-transitory computer readable medium of claim 13 , wherein applying the power comprises obtaining the power from a second power supply of the plurality of power supplies.
