Direct N_Port Attachment

Direct N_Port Attachment
The T10000 tape drives support direct attachment to a host through a host bus
adapter (HBA) that creates an N-Port. The HBA sends and receives to and from the
tape drive.
Addressing
StorageTek tape drives use: Port name, Node name, and Port ID for login validation.
The StorageTek registration ID is 24 bits consisting of:
• 00104F (hex)
TABLE 2-1 indicates the Institute of Electrical and Electronics Engineers (IEEE)
registered format for Name Address Authority (NAA), company ID, and vendor
specific identifier for a total of 64 bits.
All ports validate the logins by comparing Port Name, Node Name, and Port ID. All
three identifiers must match or this indicates the configuration has changed and
requires a Logout (LOGO).
Note – A LOGO terminates all open Exchanges between SCSI
initiator and target.
