•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.
- The Target Port Identifiers are defined in the NAA IEE WWID format where:
World Wide ID is a World Wide ID is a 64-bit unique identification for each drive. The format is: 5000CCAh
xxxh yyb n wherexxx is the 12-bit block assignment defined for each model and manufacturing site yy is the 2-bit
port/node ID select n is the 22-bit drive unique serial number.
