Lists all the subsystems on AIX’s System Resource Controller and then look for the subsystem that you want. In this example, I’ll restart sshd

root@aix:/ # lssrc -a | grep ssh
sshd ssh 340158 active

Issue the command to stop sshd

root@aix:/ # stopsrc -s sshd
0513-044 The sshd Subsystem was requested to stop.

Then start it

root@aix:/ # startsrc -s sshd
0513-059 The sshd Subsystem has been started. Subsystem PID is 340162.
