1. A computer program product for reconfiguring a cluster of computing devices running virtual machines, the computer program product comprising:
a computer readable storage device and program instructions stored on the computer readable storage device, the program instructions comprising: in response to one or more instructions to remove a first computing system of a plurality of computing systems from a computing system cluster including the plurality of computing systems, execute program instructions to modify a plurality of port names associated with a second computing system of the plurality of computing systems, wherein the second computing system includes a storage resource that is accessible via at least one of a first port and a second port that are connected to a storage area network, and wherein the first port utilizes a first active port name of the plurality of port names that is based on a first computing system identifier that is associated with the first computing system and the second port utilizes a second active port name of the plurality of port names that is based on the first computing system identifier, the program instructions to modify the plurality of port names comprising:
program instructions to terminate access via the first port, and in response, modify the first port name based on a target computing system identifier;program instructions to re-establish access via the first port;program instructions to, in response to re-establishing access via the first port, terminate access via the second port and modify the second active port name based on the target computing system identifier; andprogram instructions to re-establish access via the second port. |
