Installation and Reference Guide for HP MPIO Full Featured DSM for MSA1000/1500 (Active-Active) Disk Arrays 3.00.00 (AA-RW8AD-TE, March 2008)

state An attribute that describes the current operational condition of an object. The
possible state include:
• Good: The multipathing device can be accessed on at least one path.
• Degraded: O ne or more paths are failed to the storage unit.
target The definition of target depends on the environment:
• For parallel SCSI con fig urations, 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 W W PN. This target can
have values between 16 and 125.
• For a fabric topology, target is a m ap ping 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.
