HP 3PAR InForm OS 3.1.1 Concepts Guide

Port Location Formats
The InForm OS CLI and the InForm Management Console display the controller node Fibre Channel,
iSCSI, and Gigabit Ethernet port locations in the following format:<Node>:<Slot>:<Port>. For
example: 2:4:1.
• Node: Valid node numbers are 0-7 depending on the number of nodes installed in your system.
When viewing a system from the rear of a cabinet:
◦ F-Class nodes are numbered 0-3 from top to bottom.
◦ T-Class nodes are numbered 0-7 from left to right, top to bottom.
◦ P10000 nodes are numbered 0-7 from left to right, bottom to top.
• Slot: Valid node slot numbers are 0-9 depending on the class of nodes installed in your system.
◦ F-Class slots are numbered 0-5 from left to right.
◦ T-Class slots are numbered 0-7 from left to right.
◦ P10000 slots are numbered 0-9 from left to right, bottom to top in a node in the lower
chassis. In the upper chassis slots are numbered 0-9 from left to right, top to bottom.
• Port: Valid node port numbers are 1-4 for all Host Bus Adapters (HBA).
◦ F-Class ports are numbered from top to bottom.
◦ T-Class ports are numbered from top to bottom.
◦ P10000 ports are numbered from bottom to top in a node in the lower chassis. In the
upper chassis ports are numbered from top to bottom.
For information about controller nodes, see “HP 3PAR Storage System Hardware” (page 58).
For more information about physical port and HBA locations, see the Physical Planning Manual
for your system model.
Port Target, Initiator, and Peer Modes
The system controller node ports operate in different modes. Depending on the type of port, the
port may operate in target, initiator, or peer mode.
Fibre Channel ports use the following firmware mode settings:
• Target mode for ports that connect to hosts and receive commands from those hosts.
• Initiator mode for ports that connect to the system physical disks and send commands to those
disks.
• Initiator mode for Remote Copy over FC (RCFC).
iSCSI ports use the following firmware mode settings:
• Target mode for ports that connect to hosts and receive commands from those hosts.
Gigabit Ethernet ports use the following firmware mode setting:
• Peer mode for Ethernet ports, used for Remote Copy over IP (RCIP).
Use the InForm OS CLI or the InForm OS Management Console to view or change the current port
mode settings. For instructions on viewing or changing mode settings, see the InForm OS CLI
Administrator’s Manual and InForm OS Management Console Online Help.
