HP 3PAR OS 3.1.3 Command Line Interface Reference

NOTES
• The ct, cl2, or rate subcommands automatically resets the port for the changes to take
effect.
• Issue the showport command with either the –i or –par options to verify the success of the
controlport command. See “showport” (page 431)
• Resetting a port causes a momentary dip in throughput, but no loss of connectivity.
• The -f option forces the operation. Without the flag, the command prompts for confirmation.
In some cases, unless the TPDFORCE_OVERRIDE environment variable is set, the command
asks for confirmation even when the -f option is specified because the operation might disrupt
the system operation.
• Use caution when changing modes for ports in LSI Fibre Channel adapters. Changing the
mode of one port in a pair (for example, from initiator to target) causes the other port in the
pair to also undergo a mode change. In the case where one port in the pair is offline (and
therefore a mode change can be allowed), but the partner port is online, changing the mode
of the offline port causes the online partner port to undergo mode change as well. This results
in loss of use of the partner port because it is no longer online.
• If there are active hosts or physical disks when issuing the controlport rst or offline
commands, a warning is returned and you are prompted for confirmation to complete the
execution of the commands.
• controlport config mode changes are not allowed when ports are online.
• When issuing the controlport ct, cl2, rate, or rscn commands, if there are active
disks on the port, an error is returned. If there are active hosts on the port, the -f option is
overridden (if specified), a warning is returned, and you are prompted for confirmation to
complete the execution of the commands.
• The controlport rcip addr command is allowed only for <node:slot:port> combinations
where an interface is installed.
• Issuing the controlport rst -l command affects both ports of a port pair. Only use this
command when irreversible damage has been done to a port or port pair.
• When issuing the controlport cl2 or vcn commands, if the port is configured as peer
connection mode, an error is returned.
• If specified, <ctval> will depend on the <connmode> value:
• If <connmode> is disk, then <ctval> can only be loop
• If <connmode> is rcfc, then <ctval> can only be point
• If <connmode> is host, then <ctval> can be either loop or point
• if <connmode> is peer, then <ctval> can only be point.
