InForm OS Version 2.3.1 Remote Copy User’s Guide
■ 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.
■ 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 only allowed for node/slot/port combinations
where there is an interface installed.
■ controlport config mode changes are not allowed when ports are online.
■ The ct , cl2 , or rate subcommands automatically reset 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.
■ Resetting a port causes a momentary dip in throughput, but no loss of connectivity.
■ 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.
■ 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.
