[gpfsug-discuss] GUI followup

[Jonathan Buzzard]

We acquired a couple of refurb x3550 M5's and I have been following the 
instructions to install but I have hit a stumbling block. Basically the 
following command fails

   /usr/lpp/mmfs/gui/cli/initgui --xcat <hostname>

giving

[root at gui1 ~]# /usr/lpp/mmfs/gui/cli/initgui --xcat xcat
EFSSG4309C Host "xcat" provided as xCAT host is probably not an xCAT 
host, because /opt/xcat/bin/lsxcatd -v cannot be executed.

However that's not accurate

[root at xcat ~]# /opt/xcat/bin/lsxcatd -v
Version 2.16.3 (git commit d1cdf8b35aa5b0bd736796acafd8f051eb07b5bf, 
built Tue Dec  7 15:03:13 GMT 2021)

My guess is that the GUI node needs to be able to do passwordless SSH 
onto the xcat/confluent server. That is not setup and I can't find any 
documentation to say it should be. Noting that passwordless SSH onto the 
xcat server has never been configured on our system either for the DSS-G 
nodes or any of the compute nodes.

Am I missing something?


JAB.
