Not sure that Spectrum Scale has stated it supports the AMD epyc (Rome?) processors. You may want to open a help case to determine the cause of this problem.
Note that Spectrum Scale 4.2.x goes out of service on September 30, 2020 so you may want to consider upgrading your cluster. And should Scale officially support the AMD epyc processor it would not be on Scale 4.2.x.

Hello,
we have a gpfs v4 cluster running with 4 nsds and i am trying to add
some clients:
mmaddnode -N hpc-storage-1-ib:client:hpc-storage-1
this commands hangs and do not finish
When i look into the server, i can see the following processes which
never finish:
root 38138 0.0 0.0 123048 10376 ? Ss 11:32 0:00

/var/mmfs/ssl/stage/tmpKeyData.mmremote.38169.priv --out
/var/mmfs/ssl/stage/tmpKeyData.mmremote.38169.keystore --fips off
The node is an AMD epyc.
Any idea what could cause the issue?
ssh is possible in both directions and firewall is disabled.
Kind regards
