state An attribute that describes the current operational condition of an object.
The possible states include:
• Good — The multipathing device can be accessed on at least one
path.
• Degraded — One or more paths are failed to the storage unit.
target The definition of target depends on the environment:
• For parallel SCSI configurations, the target is the actual target number
assigned to a device.
• For Fibre Channel configurations, a target number is assigned by a
mapping function at the miniport-driver level and is derived from AL_PA
(Arbitrated Loop Physical Addresses) in an FC-AL topology.
• For SAN switched fabric, a target is assigned to a WWPN. This target
can have values between 16 and 125.
• For a fabric topology, target is a mapping function derived from the
order of discovery according to port connections at the SAN (Storage
Area Network) switch.
topology An interconnection scheme that allows multiple servers and storage devices
to communicate. Arbitrated loop and switched fabric are examples of Fibre
Channel topologies.
