Hi Sandra,
Is the mgt0 and mgt0-pub pointing to the same IP address, or in the same subnet? And what's your `mgt01` definition, you can use `lsdef mgt01` to get the information and hide the sensitive attributes.
And Yuan, do you have more suggestions?

Subject: [xcat-user] unexpected hostname
Date: Thu, Oct 25, 2018 11:35 PM
Hi all,xCAT/HPC/list newbie here!I have recently configured an xCAT node and am attempting to provision a separate management node, but for some reason xCAT is sort of not applying the expected hostname.I'd like the resulting hostname on the node to just be "mgt0", but instead it's tacking on the public NIC suffix as well as the FQDN, i.e. mgt0-pub.meerkat.mcri.edu.auThe cluster is entirely CentOS7 based and will be eventually utilising MOAB and PBS/Torque for scheduling and resource management. The version of xCAT for this particular build is v2.14.4.I've trawled through the debug enabled build logs and stepped through post.rh.common and from what I can tell the node should just be named "mgt0" (sans all suffixes).Also, the DNS on the xCAT node contains entries for "mgt0", "mgt0-data", "mgt0-pub", but (if this is indeed the issue) I'm not sure why xCAT would have selected "mgt0-pub" to hand out when the node is being provisioned via its management IP which is actually associated with "mgt0" (as opposed to its public one which is associated with "mgt0-pub").Any ideas on other avenues that might be worth investigating?Also, please feel free recommend some useful resources for learning xCAT and/or HPC in general! I'm already heavily utilising the official xCAT docs and the Sourceforge Wiki/mailing list search...Cheers,SandraSent from ProtonMail, encrypted email based in Switzerland._______________________________________________
