path A path to a device is a combination of an adapter port instance and a target port as distinct from
internal paths in the fabric network. A fabric network appears to the operating system as an
opaque network between the initiator and the target.
ping A computer network administration utility used to test whether a specified host is reachable across
an IP network, and to measure the round-trip time for packets sent from the local host to a
destination computer.
