Issue/Introduction

  • NSX Manager Appliances are not showing up on the NSX UI - Cluster shows as UNAVAILABLE
  • No impact observed on data-path
  • Following log lines in var/log/nsxapi.log file indicate issues with DNS:

12:49:16.852Z INFO http-nio-127.0.0.1-7440-exec-6 Utils 139026 - [nsx@6876 comp="nsx-manager" level="INFO" reqId="########-656a-4ebd-b393-############" subcomp="manager" username="admin"] Executing script: /opt/vmware/nsx-common/python/nsx_utils/ip_utils.py -d4 ##-nsx-manager.systems.##.####

We can observe above that ip_utils.py took 15 seconds to respond

Environment

VMware NSX

Cause

Problems with DNS configuration can lead to this issue. For example, DNS configuration is pointing to a server that does not exist or is unavailable.

Resolution

Check the contents of /etc/resolv.conf file in all NSX Managers and ensure that the configured DNS servers are correct, available and in right order.
