Intelligent rolling upgrade for data storage systems
First Claim
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,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;
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; and
if the node down tolerance factor has not been exceeded, checking a cluster health to ensure cluster resources of a computing cluster are not removed such as to render the computing cluster inoperable during an automated code upgrade associated with the plurality of rolling upgrade policies.

Abstract
Various method, system, and computer program product embodiments for facilitating upgrades in a computing storage environment are provided. In one such embodiment, one of an available plurality of rolling upgrade policies is defined by specifying the at least one selectable upgrade parameter, including specifying one of a commencement time and duration of an upgrade procedure. A node down tolerance factor is set for at least one node in the computing storage environment. A determination of whether 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 is not exceeded, a cluster health is checked.

11. A computer program product for facilitating upgrades in a computing storage environment by a processor in communication with a memory device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
-
an executable portion for selecting one of an available plurality of rolling upgrade policies registering at least one selectable upgrade parameter for an upgrade window; an executable portion for setting a node down tolerance factor for at least one node in the computing storage environment; an executable portion for 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; an executable portion for, 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; and an executable portion for, if the node down tolerance factor has not been exceeded, checking a cluster health to ensure cluster resources of a computing cluster are not removed such as to render the computing cluster inoperable during an automated code upgrade associated with the plurality of rolling upgrade policies. - View Dependent Claims (12, 13, 14)
