Abstract:
1. A method for facilitating upgrades in a computing storage environment by a processor in communication with a memory device, comprising: 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 node down tolerance factor has not been exceeded, checking a cluster health by checking a general parallel file system (GPFS) cluster quorum to determine if taking the target node to be upgraded offline does not break the GPFS quorum.
