P

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 adapter (initiator) and the target.

Because a path is a combination of an adapter and a target port, it is distinct from another path
if it is accessed through a different adapter or it is accessing a different target port. Consequently,
when switching from one path to another, the driver might be selecting a different adapter
(initiator), a different target port, or both.

This is important to the driver when selecting the proper method of failover notification. It can
make a difference to the target device, which might have to take different actions when receiving
retries of the request from another initiator or on a different port.
