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
Address Authority (NAA), company ID, and vendor-specific identifier.

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).
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.
The library sets the Protocol Identifier field to 0h (Fibre)
The library returns a value of 1, indicating the identifier contains binary
values.
3 = The identifier field contains a 64-bit IEEE formatted address
■
4 = The identifier field contains a 4-byte port number
■
04h = The identifier field is 4-bytes long
■
08h = The identifier field is 8-bytes long
■
Contains a binary value of the identifier
The library returns a value of 1, indicating the identifier type is valid
0 = Identifier field is associated with the addressed logical unit
■
1 = Identifier field is associated with the port that received the request
