Abstract:
1. A method for facilitating upgrades in a computing storage environment by a processor in communication with a memory device, comprising: defining and selecting one of an available plurality of rolling upgrade policies registering at least one selectable upgrade parameter for an upgrade window; setting a node down tolerance factor for at least one node in the computing storage environment, wherein the node down tolerance factor specifies a percentage of elements of the at least one node taken offline to apply the selected one of the available plurality of rolling upgrade policies during the upgrade window; determining if a number of at least one of a plurality of nodes in the computing storage environment currently down, including a target node to be upgraded, does not exceed the node down tolerance factor; and if the target node to be upgraded is an interface node, determining if at least one additional interface node is available to fail over internet protocol (IP) addresses exported by the interface node.
