Issue/Introduction

VDT logs for vCenter show the following:

[FAIL]   vc (VR/SRM 9.0)

[FAIL]    SSL Connectivity

Investigate error: [vc:443]:[Errno -2] Name or service not known

 

 

Testing connectivity with nc -z shows the following:

nc -z vc 443

Error "Couldn't resolve host "vc"

Environment

vCenter 8

Cause

/etc/resolv.conf had nameserver entries configured but not search

vCenter VAMI/VCSA UI only has option to configure the DNS servers

Use vami_config_net to configure additional DNS settings

Resolution

Take a snapshot of the vCenter VM before proceeding. If using ELM take offline snapshots of all vCenters

SSH into vCenter and run the following:

/opt/vmware/share/vami/vami_config_net

Select 0 to capture the current configuration

Then select 4 to configure DNS and it will ask for the DNS servers and domain.
