Stopping and starting an AIX Subsystem

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.
