Environment

VVF 9.x

Cause

The following command was executed to check the VMDir state, which returned Standalone.
/usr/lib/vmware-vmafd/bin/dir-cli state get --login --password --server-name --domain-name

Resolution

1. Took a snapshot of the vCenter
   
   
2. To set vmdir to NORMAL mode do the following:
   Update the registry values in lwregshell
   /opt/likewise/bin/lwregshell set_value '[HKEY_THIS_MACHINE\Services\vmdir]' "Arguments" "/usr/lib/vmware-vmdir/sbin/vmdird -l 0 -f /usr/lib/vmware-vmdir/share/config/vmdirschema.ldif -L /var/log/vmware/vmdird/vmdird.log"
   Refresh the Likewise registry using below command
   /opt/likewise/bin/lwsm refresh
   Change VMDIR state to NORMAL
   /usr/lib/vmware-vmafd/bin/dir-cli state set --state NORMAL --login administrator --password <password>
   
   
3. Reboot the vCenter and verify if the vmdir state still remained in  NORMAL state?
   /usr/lib/vmware-vmafd/bin/dir-cli state get

4. Retry the backup
