■ Node: Valid node numbers are 0-7 for each storage server, depending on the number of
nodes and the storage server model.
■ Slot: Valid slot numbers are 0-7 for S-Class and T-Class storage server nodes, and 0-5 for E-
Class and F-Class storage server nodes. Slots are numbered consecutively from left to right.
■ Port: Valid port numbers are 1-4 for each Host Bus Adapter (HBA), ports are numbered
consecutively from top to bottom on most nodes.
6.2.1 FC Port Settings
The InForm CLI controlport command is described in detail the 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 InServ Storage Server.
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 InServ Storage Server.
■ 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 the
controlport 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 the
controlport 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.
