Abstract
A method (and structure) of operating an operating system (OS) on a computer. When a failure of the OS is detected, the computer automatically performs a diagnosis of the OS failure. The computer also attempts to automatically repair/recover the failed OS, based on the diagnosis, without requiring a reboot.
Claims22
A method of operating an operating system (OS) instance on a computer, said method comprising:
- detecting a failure of said OS instance;
- and
- automatically performing a diagnosis of said OS failure, using a processing on said computer.
An apparatus, comprising:
- at least one processor executing at least one operating system (OS) instance,
- wherein, when a failure of said OS instance is detected, said processor automatically performs a diagnosis of said OS failure.
A mechanism to attempt to automatically recover a failed operating system (OS) instance on a computer or LPAR, said mechanism comprising:
- a detector that provides an indication that an OS instance has failed;
- a diagnosis-and-recovery kernel embedded in a protected region of said OS instance;
- and
- memory space allocated for automatically storing information during a failure of said OS instance,
- wherein, upon said OS instance having been detected as failed, said diagnosis-and-recovery kernel automatically performs a diagnosis of said OS failure, using said automatically-stored information, and attempts to automatically repair/recover said failed OS, based on said diagnosis, without rebooting.
