# refresh -s sshd
0513-005 The Subsystem, sshd, only supports signal communication.

In order to have a process such as SSHD re-read its configuration file (/etc/ssh/sshd_config), you must do a "stopsrc -s sshd" followed by a "startsrc -s sshd":

# stopsrc -s sshd
0513-044 The sshd Subsystem was requested to stop.
# startsrc -s sshd
0513-059 The sshd Subsystem has been started. Subsystem PID is 3670044.

As you can see when you do the "stopsrc" it just says the process was requested to stop; not that it was stopped.   This implies that there might be a delay before the process actually stops.  

So what a lot of people do in scripts where they need to restart processes like this is something like this:

stopsrc -s sshd

sleep 10
startsrc -s sshd

Here is a one liner to request a stop to a SRC process like SSHD, verify it is stopped, and then restart it:

stopsrc -s sshd && until lssrc -s sshd | grep -q inoperative; do echo "Waiting for sshd to stop"; perl -e 'select(undef,undef,undef,.25)'; done && startsrc -s sshd
