Fibre Channel Port Control Mode Page
This page is supported for Fibre Channel only:
The Fibre Channel Port Control Page allows you to set the initialization and
addressing behavior of the Fibre Channel interface.
EPDC 0 The target does not use the precise delivery function and ignores the contents of the CRN field
in the Fibre Channel Extended Link Service FCP_CNTL. HP Ultrium drives support this feature
by default.
1 The logical unit uses the precise delivery function defined in the FCP-2 standard. It makes use
of the CRN field.

PLPB Prevent Loop Port Bypass
0 The target allows the Loop Port Bypass (LPB) and Loop Port Enable (PBE) primitive sequences
to control the port bypass circuit.
1 The target ignores any Loop Port Bypass (LPB) and Loop Port Enable (LPE) primitive
sequences. The loop port remains enabled.
DDIS Disable Discovery
0 The target must wait to receive an Address Discovery Link Service (ADISC) or Port Discovery
Link Service (PDISC) before it resumes processing tasks for the initiator.
1 The target does not require receipt of address or Port Discovery following loop initialization.
It resumes processing of tasks on completion of loop initialization.
