HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

FC Port Settings
The InForm OS CLI controlport command is described in detail the HP 3PAR InForm OS
Command Line Interface Reference and the CLI Help Pages. Use the controlport command to
perform the following tasks.
• Set the port’s mode with the config sub-command followed by disk|host|rcfc and the
port location in Node:Slot:Port format.
To set the port’s mode:
1. Disconnect the cable from the port on the system.
2. Set the port’s mode. Issue the controlport config
disk|host|rcfc<Node>:<Slot>:<Port> command.
3. Reconnect the cable to the port on the system.
• Set the port’s data rate in Gbps with the rate sub-command followed by 1, 2 or 4 and then
by the port location in Node:Slot:Port format. Alternatively, you can use controlport
rate auto followed by the port location in Node:Slot:Port format to allow the system
to determine the data rate automatically. The default value for this option is auto.
To set the port’s data rate in Gbps, issue thecontrolport rate <1|2|4>
<node:slot:port> command.
• When unique_nwwn is enabled, the port presents a unique node name for the connection.
To set the mode of an FC port, or set the unique node WWN option for the port, issue
thecontrolport config <connmode> [-ct <ctval>] [-unique_nwwn
enable|disable] <node:slot:port> command, where:
◦ <connmode> is the one of the following connections: disk|host|rcfc.
◦ <ctval> is either loop or point. The loop parameter sets the port to arbitrated loop
mode, the point parameter sets the port to point-to-point mode.
• Set the port’s Class 2 service support level with the cl2 sub-command followed by ack0,
ack1, or disable and then by the port location in Node:Slot:Port format.
To set the port’s Class 2 service support level, issue the controlport cl2 <cl2val>
<node:slot:port> command.
• Set the port’s VLUN Change Notification (VCN) support generation with the vcn sub-command
followed by either enable or disable and then by the port location in Node:Slot:Port
format.
To set the port’s VLUN Change Notification (VCN) support, issue the controlport vcn
<enable|disable> <node:slot:port> command.
NOTE: Other options are available for the controlport command, including options for
resetting the port’s mode, modifying Remote Copy settings, and issuing an FC Loop Initialization
Primitive (LIP) procedure. These options are described in detail the HP 3PAR InForm OS Command
Line Interface Reference and the CLI Help Pages.
