Abstract
Mechanisms are provided for performing a live update of an operating system. The mechanisms receive an update to an operating system and clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group. The mechanisms apply the update to the cloned root volume group to generate an updated and cloned root volume group and boot a second logical partition of the data processing system using the updated and cloned root volume group. Moreover, the mechanisms migrate application instances and application data to the second logical partition.

11. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:
-
receive an update to an operating system; clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group; apply the update to the cloned root volume group to generate an updated and cloned root volume group; boot a second logical partition of the data processing system using the updated and cloned root volume group; and migrate application instances and application data to the second logical partition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An apparatus comprising:
-
a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to; receive an update to an operating system; clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group; apply the update to the cloned root volume group to generate an updated and cloned root volume group; boot a second logical partition of the data processing system using the updated and cloned root volume group; and migrate application instances and application data to the second logical partition.
