1. A computer comprising a memory storing a software and a processor executing the software, wherein the software is operable to:

  • receive an identification of storage ports of a storage system corresponding to a volume to be provisioned;

    after receiving the identification of the storage ports, gather preset server configuration information including server ports of a plurality of servers managed by the computer;

    after receiving the identification of the storage ports, gather preset FC-SW configuration information including discovered WWNs of the server ports and the storage ports;

    after receiving the identification of the storage ports, gather preset storage configuration information including the identified storage ports;

    check whether a redundant relationship is formed by a first physical connection between a first server port of the gathered server ports of the plurality of servers and a first storage port of the identified storage ports of the storage system by matching a WWN of the first server port and a WWN of the first storage port with the discovered WWNs gathered from FC-SW and a second physical connection between a second server port of the gathered server ports of the plurality of servers and a second storage port of the identified storage ports of the storage system by matching a WWN of the second server port and a WWN of the second storage port with the discovered WWNs gathered from FC-SW, to validate the first and second physical connections;

    validate whether each of the first server port the second server port connects to a FC-SW'"'"'s independent domain based on the discovered WWNs of the server ports; and

    provision the volume from the storage system after validating the redundant relationship.
