Olaf, Correct.
mmchconfig -i is accepted for tscCmdPortRange . The change should take place immediately, upon invocation of the next command.

"where" to send the output of a command... and for those admin ports .. so called ephemeral ports... it depends , how much admin commands ( = sessions = sockets) you want to run in parallel in my experience.. 10 ports is more than enough we use those in a range from 50000-50010 to be clear .. demon - to - demon .. communication always uses 1191 cheers From: "Simon Thompson (IT Research Support)" <s.j.thomp...@bham.ac.uk> To: "gpfsug-discuss@spectrumscale.org" <gpfsug-discuss@spectrumscale.org> Date: 03/06/2018 06:55 PM Subject: [gpfsug-discuss] tscCmdPortRange question Sent by: gpfsug-discuss-boun...@spectrumscale.org We are looking at setting a value for tscCmdPortRange so that we can apply firewalls to a small number of GPFS nodes in one of our clusters. The docs don’t give an indication on the number of ports that are required to be in the range. Could anyone make a suggestion on this? It doesn’t appear as a parameter for “mmchconfig -i”, so I assume that it requires the nodes to be restarted, however I’m not clear if we could do a rolling restart on this?
