check your /etc/resolv.conf, you can get rid of 169 ip address and use head's ip address, then run makedns again.

The effect of this is that the head node has 2 entries in the local DNS cache. One for its private IP address (in /etc/hosts) and one for the other address which is not reachable by the compute nodes. The other IP address is just used by the HW management utilities for internal communications and is a 169.x.x.x address. How can I tell xCat/makedns to not create this entry? -SS-_______________________________________________ xCAT-user mailing list xCAT-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcat-user _______________________________________________ xCAT-user mailing list xCAT-user@lists.sourceforge.net https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.sourceforge.net_lists_listinfo_xcat-2Duser&d=DwICAg&c=jf_iaSHvJObTbx-siA1ZOg&r=n1LR_Py9TQX0dVqfGTbLHUMGx25-C8VtBDS0nCzyNXY&m=shQO-5MBva2oCgDpF2PjvfGhZrFOSdNRkr8lno6yWMo&s=RdRtvWaKiWiFiRv2Cv4ClCci4sFCrlXzpuOWKPQRtK4&e=
