• Protocol Identifier is valid only when PIV=1. Protocol Identifier = 0 indicates Fibre Channel devices. Protocol Identi-
fier = 6 indicates SAS devices
• Code Set specifies the data type for the identifier field. Code Set = 1 indicates binary data
• PIV (Protocol Identifier Valid) set to one indicates that the Protocol Identifier field contains a valid value.
• Association specifies the entity with which the Identifier field is associated: 1h for Target or Relative Port.
• Identifier Type specifies the format and assignment authority for the identifier: 3h indicates NAA format of the WWID
for Target Port.
• Identifier fields contain the actual Identifier Descriptor.
