Re: [gpfsug-discuss] tscCmdPortRange question

[Olaf Weiser]

this parameter is just for administrative
commands.. "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 5-50010
to be clear .. demon - to - demon .. communication
always uses 1191cheersFrom:

tscCmdPortRange questionSent by:    
   gpfsug-discuss-boun...@spectrumscale.orgWe 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? Thanks Simon___gpfsug-discuss mailing listgpfsug-discuss at spectrumscale.orghttp://gpfsug.org/mailman/listinfo/gpfsug-discuss
