1. A method for reconfiguring a cluster of computing devices running virtual machines, the method comprising:
- in response to removing a first computing system of a plurality of computing systems from a computing system cluster including the plurality of computing systems, modifying 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, modifying the plurality of port names comprising;
terminating access via the first port, and in response, modifying the first port name based on a target computing system identifier;
re-establishing access via the first port;
in response to re-establishing access via the first port, terminating access via the second port and modifying the second active port name based on the target computing system identifier; and
re-establishing access via the second port.

Abstract
Assigning a set of port names to storage access paths of virtual machines accessing storage resources via storage area networks is provided. A first computing system cluster that is associated with a set of computing system identifiers is created. A first computing system identifier associated with a first computing system is added to the set of computing system identifiers. The first computing system is disassociated from the first computing system identifier. The first computing system is added to the first computing system cluster.

11. A method for reconfiguring a cluster of computing devices running virtual machines, the method comprising:
in response to removing a source computing system of a plurality of computing systems from a computing system cluster including the plurality of computing systems, migrating a virtual machine of the source computing system to a destination computing system of the plurality of computing systems, wherein (i) the virtual machine is associated with a first port name and a second port name, (ii) the virtual machine can access a storage resource via a storage area network utilizing active port names, and (iii) the virtual machine cannot access the storage resource via the storage area network utilizing inactive port names, and wherein migrating the virtual machine comprises; in response to determining that the first port name is an inactive port name with respect to a port of the source computing system, modifying the first port name with respect to the port associated with the source computing system based on a target computing system identifier of a set of computing system identifiers; creating a copy of the virtual machine on the destination computing system, wherein the copy of the virtual machine on the destination computing system is associated with the modified first port name; activating the modified first port name with respect to a port associated with the destination computing system such that the modified first port name is an active port name, and in response; deactivating the second port name with respect to a port of the destination computing system such that the second port name is an inactive port name; and modifying the second port name with respect to the port of the destination computing system based on the target computing system identifier. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
