Add External PSC 6.0 U2 to Active Directory Domain

I have been thinking of writing this post for a while and here you go…

In vSphere 6.0 U2, you can have an External PSC or an Embedded PSC. The below process is to add an External PSC to the Active Directory Domain.

Login into the vCenter server, go to Administration tab, go to System Configuration –> Nodes and click on the PSC node you want to add to the domain.

Click on the node, go to Manage tab, click on Active Directory and click on Join button
Provide the Domain name and its credentials (It could be a read-only service account in the domain) to join the PSC to the domain


once credentials are provided, click OK to proceed.

Note that the only way for you to know that this process is complete is that you get no error and there is no entry in the recent tasks tab in the vSphere web client. If that is the case then the domain add is successful.

Now, you will need to reboot the PSC

Once the PSC is rebooted, you can go back into the vCenter server and to the node and you can see that this node (PSC) is now added to the domain.

In a similar way, you can add the remaining PSC’s to the domain and finally, you will need to add the Identity source to the vCenter server itself under single sign-on



SSO Server test failed when Configuring VDP 6.1.8 during vCenter Registration

Recently, I came across an issue while configuring a new instance of VDP 6.1.8 appliance while performing vCenter Registration to the vCenter appliance 6.5 with an external Platform Services Controller.

below is the error message I have been getting


I have provided the administrator account user credentials to the VCSA (vCenter server) with the default ports but still received the error.

Upon some deep troubleshooting, found out that the SSO server is the Platform Services Controller (PSC) since my environment had an external PSC and here is how you resolve this issue:

De-select the checkbox “Use vCenter for SSO authentication”, and add the Platform Services Controller hostname/IP in the new SSO entry line.


Now, you can test the connection and it will be a success


This is how the issue was resolved. Hope it helps someone out there.

This is with VDP version 6.1.8 connecting to VCSA 6.5 with External PSC

PSC’s fail to join Domain after Upgrade from vSphere 6.0 U2 to 6.0 U2b or 6.0U3b

Recently, I have come across an issue with the PSC’s not joining to the domain (They disconnected from the domain automatically) after upgrading the vCenter components (PSC01, PSC02 and vCenter windows server) from 6.0 Update 2 build 3634791 to 6.0 Update 2a build 4632154 or to 6.0 Update 3b build 5326079. This issue occurred as the windows domain controller was 2012 R2 and SMB 2 was the communication protocol to the domain controller. we have to enable SMB 2 on the PSC’s for them to communicate to the domain after the Upgrade.

here is the process to enable SMB2 on the PSC’s —

login to PSC01 and run the following command to check the values

/opt/likewise/bin/lwregshell list_values '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]'

check the value of “Smb2Enabled”, this value will be 0, we will need to change it to 1 to enable it.

change SMB2 to be Enabled

/opt/likewise/bin/lwregshell set_value '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]' Smb2Enabled 1

Once enabled, we need to restart the service lwio

/opt/likewise/bin/lwsm restart lwio

Check the values again —

/opt/likewise/bin/lwregshell list_values '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]'

This time the value of “Smb2Enabled” will be 1.

This process is repeated for PSC02 as well and once this is done on both the PSC’s, you can go ahead and add the PSC’s to the domain and the function works !!

The process to change the SMB value on ESXi 6.0 is a little different and here are the commands —

Check values —

/usr/lib/vmware/likewise/bin/lwregshell list_values ‘[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]’

Change SMB2 to be enabled

/usr/lib/vmware/likewise/bin/lwregshell set_value ‘[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]’ SMB2Enabled 1

Restart lwio service

/usr/lib/vmware/likewise/bin/lwsm restart lwio


Reset root password on vCenter PSC 6.0 U2

Resetting the root password on a Platform Services Controller (PSC) 6.0 U2 is taken from the following link —

Link to Reset PSC root Password

The above website clearly mentions on how to use the SUSE Linux Rescue CD to create a new root password and update it in the /etc/shadow file on the PSC itself and after reboot you will be able to get into the PSC with the new password.

Hope this helps !!

Restart the services in VCSA 6.0

Recently I had to restart the web-client service in vcsa 6.0 U1 appliance and found out that the web client service is called differently than in the windows vCenter. the web client service in the vcsa is called vSphere-client

here are the commands to start, stop and restart any services in the vcsa appliance.

To restart a vCenter Server and/or Platform Services Controller service using the command-line:
Log in as root through an SSH or console session on the vCenter Server Appliance.
Run this command to enable the shell:

shell.set --enabled true

Run this command to launch the shell:


Run this command to change directories to /bin:

cd /bin

Run this command to list the vCenter Server Appliance services:

service-control --list

Run this command to stop a specific service:

service-control --stop servicename

You may also stop all services by typing the command:

service-control --stop --all

Run this command to start a specific service:

service-control --start servicename

You may also start all services by typing the command:

service-control --start --all

Here are all the services in the vCenter server appliance –>
