98 SL500: Interface Reference Manual • July 2008 Revision: F • 96122
The 36-bytes of the device identification page indicates the vendor-specific portion
of the Institute of Electrical and Electronics Engineers (IEEE) registered 64-bit ID
for a Fibre Channel library.
The vendor-specific portion of the ID includes the library’s Port name, Node name,
and N_Port ID. This information is unique for each Fibre Channel interface card in
the library.
The remaining 28 bits of the library’s ID consist of:
■ Name Address Authority (5h)
■ Sun StorageTek company ID (00104Fh)
TABLE 6-13 shows the 64-bit IEEE-registered format that includes the Name
Address Authority (NAA), company ID, and vendor-specific identifier.
Note – Every device on the loop must have a unique ID for login validation.
Device Identification Page Definitions:
Peripheral Qualifier The library returns a value of 000b indicating the specified peripheral device
type is currently connected to this logical unit. If the command is sent to an
unsupported logical unit, the value returned is 011b.
(Note: xxxb indicates binary notation).
Peripheral Device Type The library returns a value of 8h, which indicates that the library is a medium
changer device. If the command is sent to an unsupported logical unit, the
value returned is 1Fh.
Protocol Identifier The library sets the Protocol Identifier field to 0h (Fibre)
Code Set The library returns a value of 1, indicating the identifier contains binary
values.
Identifier Type
■ 3 = The identifier field contains a 64-bit IEEE formatted address
■ 4 = The identifier field contains a 4-byte port number
Identifier Length
■ 04h = The identifier field is 4-bytes long
■ 08h = The identifier field is 8-bytes long
Identifier Contains a binary value of the identifier
PIV The library returns a value of 1, indicating the identifier type is valid
Association
■ 0 = Identifier field is associated with the addressed logical unit
■ 1 = Identifier field is associated with the port that received the request
