Issue/Introduction

Symptoms:
  • A convergence of the PSC fails. 
  • vCenter Server services fail to start.
  • The /var/log/vmware/vpxd/vpxd.log file contains no new entries.
  • In the /var/log/vmware/vmon/vmon.log file, you see entries similar to:

  • In the /var/log/vmware/vmdird/vmdird-syslog.log file, you see entries similar to:
<YY-MM-DD>T<TIME> err vmdird  t@140166960015104: VmDirSRPGetIdentityData ([email protected]) failed, (9611)

  • The command /opt/likewise/bin/lwregshell list_values "[HKEY_THIS_MACHINE\Services\vmafd\Parameters]" | grep DomainState returns the output:
+  "DomainState"             REG_DWORD       0x00000000 (0)


Environment

VMware vCenter Server Appliance 6.7.x
VMware vCenter Server Appliance 6.5.x

Cause

The issue occurs as a result of a failed convergence.

Resolution

To resolve the issue, follow the steps below:
  1. Recreate the computer account for the vCenter Server by following the Resolution outlined in Recreate vCenter Server Machine Account in Platform Services Controller after Failed Convergence.
  2. Move the file /root/velma/afd.db to the directory /storage/db/vmware-vmafd/ using the command:
mv /root/velma/afd.db /storage/db/vmware-vmafd/afd.db;
 
  1. Run the command below to configure the DomainState of the vCenter Server to an external topology:
/opt/likewise/bin/lwregshell set_value "[HKEY_THIS_MACHINE\Services\vmafd\Parameters]" "DomainState" 2;
 
  1. Restart the vCenter Server services using the command below:
service-control --stop --all;service-control --start --all;
 


Workaround:
Restore both the PSC and the vCenter server from a backup which was taken while both nodes were offline. Please note that restoring a backup of just one node can have adverse effects on the environment.
