Abstract
An apparatus, system, and method are disclosed for quiescing a boot environment. A reservation module reserves a portion of a first storage device. A store module stores an update boot image to the reserved portion. A detection module detects the update boot image stored on the first storage device when the computer boots and executes the update boot image in place of a standard boot image in response to detecting the update boot image. The update boot image places a computer in a known quiescent state.
Claims19
A computer readable storage medium comprising a computer readable program stored on a tangible storage device for quiescing a boot environment, wherein the computer readable program when executed on a computer causes the computer to:
- reserve a portion of a first storage device;
- store an update boot image to the reserved portion;
- detect the update boot image stored on the first storage device when the computer boots;
- and
- execute the update boot image in place of a standard boot image in response to detecting the update boot image, wherein the update boot image places the computer in a known quiescent state that does not access a first component;
- and
- update firmware for the first component, the first component comprising a component processor and a component memory separate and distinct from a processor and a memory of the computer.
An apparatus comprising:
- a second storage device storing a computer readable program executed by a second processor, the computer readable program comprising:
- a reservation module reserving a portion of a first storage device;
- a store module storing an update boot image to the reserved portion;
- a detection module detecting the update boot image stored on the first storage device when a computer boots, executing the update boot image in place of a standard boot image in response to detecting the update boot image, wherein the update boot image places the computer in a known quiescent state that does not access a first component, and updating firmware for the first component, the first component comprising a component processor and a component memory separate and distinct from the second processor and the second storage device.
A system comprising:
- a disk cache;
- a memory storing a computer readable program;
- a processor executing the computer readable program, the computer readable program comprising
- a reservation module reserving a portion of the disk cache;
- a store module storing an update boot image to the reserved portion;
- a detection module detecting the update boot image stored on the disk cache when the processor boots and executing the update boot image in place of a standard boot image in response to detecting the update boot image, wherein the update boot image places the system in a known quiescent state that does not access a first component and updates firmware for the first component, the first component comprising a component processor and a component memory separate and distinct from the processor and the memory.
