Upgrade management for a shared pool of configurable computing resources
First Claim
1. A computer-implemented method of upgrade management for a shared pool of configurable computing resources having a set of logical partition (LPAR) nodes which includes a set of established members, the method comprising:
- initiating, with respect to a first original LPAR node which has a set of original assets, performance of a live kernel update (LKU) operation;
initiating, to succeed the first original LPAR node as a first established member of the set of established members, generation of a first surrogate LPAR node which has a set of successor assets to succeed the set of original assets;
identifying, pertaining to LPAR node management in advance of the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node as a new original LPAR node;
joining the first surrogate LPAR node with the set of LPAR nodes;
identifying, pertaining to LPAR node management in response to the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node as a new surrogate LPAR node; and
establishing, to facilitate utilization of the set of successor assets, the first surrogate LPAR node as the first established member of the set of established members thereby removing the first original LPAR node from the set of established members.

Abstract
Disclosed aspects relate to upgrade management for a shared pool of configurable computing resources having a set of logical partition (LPAR) nodes which includes a set of established members. Performance of a live kernel update (LKU) operation may be initiated with respect to a first original LPAR node. Generation of a first surrogate LPAR node to succeed the first original LPAR node may be initiated. The first surrogate LPAR node may be identified as a new original LPAR node. The first surrogate LPAR node may be joined with the set of LPAR nodes. In response to the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node may be identified as a new surrogate LPAR node. The first surrogate LPAR node may be established as a first established member, thereby removing the first original LPAR node from the set of established members.

19. A computer program product of upgrade management for a shared pool of configurable computing resources having a plurality of logical partition (LPARs) nodes which includes a set of established members, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:
-
initiating, with respect to a first original LPAR node which has a set of original assets, performance of a live kernel update (LKU) operation; initiating, to succeed the first original LPAR node as a first established member of the set of established members, generation of a first surrogate LPAR node which has a set of successor assets to succeed the set of original assets; identifying, pertaining to LPAR node management in advance of the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node as a new original LPAR node; joining the first surrogate LPAR node with the set of LPAR nodes; identifying, pertaining to LPAR node management in response to the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node as a new surrogate LPAR node; and establishing, to facilitate utilization of the set of successor assets, the first surrogate LPAR node as the first established member of the set of established members thereby removing the first original LPAR node from the set of established members. - View Dependent Claims (20)
