Dynamically configuring the environment of a recovery OS from an installed OS
First Claim
1. A method in a computing system comprising:
- initiating reboot of an operating system into a recovery environment;
performing discovery to identify an installed operating system, wherein said discovery comprises discovering physical disks coupled to said computing system, identifying logical volumes on each of said physical disks, and examining each of the logical volumes for installed operating systems;
determining configuration information of the installed operating system; and
utilizing the configuration information to establish an operating environment for the recovery environment;
scheduling in a first environment a task for execution in said recovery environment, wherein said task is scheduled prior to said reboot, wherein completion of said task requires assignment of a given resource to a same drive letter in both the recovery environment and the first environment.

Abstract
A system and method for rebooting an operating system into a recovery environment. A computing system is configured to reboot an operating system into a recovery environment which mimics the environment of an installed operating system. Subsequent to initiating the reboot, the system performs a discovery operation to identify operating systems which are installed on the system. Upon identifying a type and/or version of an operating system which is installed, processes corresponding to an identified operating system are initiated to determine configuration information of the operating system. Subsequently, the determined configuration information is used to establish an environment for the recovery environment which mimics that of the installed operating system. Discovery procedures may include discovering physical disks coupled to the system, identifying logical volumes on each of the disks, and examining each of the logical volumes for installed operating systems. Ordinary boot of the system, and reboot of the system, may be accomplished via different devices. Reboot may be accomplished via portable media such as CD-ROM.

5. A computing system comprising:
-
a host including a memory; a storage device; and a processor, wherein the processor is configured to; initiate reboot of an operating system of the host into a recovery environment; perform discovery to identify an operating system installed on the host, wherein in performing said discovery, the processor is configured to discover physical disks coupled to said computing system, identify logical volumes on each of said physical disks, and examine each of the logical volumes for installed operating systems; determine configuration information of the installed operating system; utilize the configuration information to establish an operating environment for the recovery environment; and schedule in a first environment a task for execution in said recovery environment, wherein said task is scheduled prior to said reboot, and wherein completion of said task requires assignment of a given resource to a same drive letter in both the recovery environment and the first environment. - View Dependent Claims (6, 7, 8, 9, 10)

11. A computer readable storage medium comprising program instructions, wherein the instructions are executable to:
-
initiate reboot of an operating system of the host into a recovery environment; perform discovery to identify an operating system installed on the host, wherein in performing said discovery, the processor is configured to discover physical disks coupled to said computing system, identify logical volumes on each of said physical disks, and examine each of the logical volumes for installed operating systems; determine configuration information of the installed operating system; utilize the configuration information to establish an operating environment for the recovery environment; and schedule in a first environment a task for execution in said recovery environment, wherein said task is scheduled prior to said reboot and wherein completion of said task requires assignment of a given resource to a same drive letter in both the recovery environment and the first environment. - View Dependent Claims (12)
