Appl. No.:

12/757688

Edward G. Butt - Tucson AZ, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30
G06F 7/00

US Classification:

707803, 707638, 707610

Abstract:

A technique for updating elements in a data storage facility, including a single server or a multi-server system, such as by providing updated internal code packages to the elements. The update is performed using a fixed state machine, where the elements are updated in a coordinated manner within the constraints of the state machine. In a multi-server device, code packages are distributed to elements associated with the different servers in one traversal of the state machine, during distribute states of the state machine. The distributed code packages are activated in activate states of the state machine in multiple traversals of the state machine, so there is a serial activation. The code packages can be grouped in a flexible way by configuring an external update bundle used by the state machine. The distributing of the code is based on the grouping.
