Reconfiguring vCenter appliance with Embedded PSC to External PSC

I was working with one of my customer who has Embedded PSC vCenter 6.0 and he wanted to configure a New vCenter with Enhanced linked mode with the present vCenter.

So as a pre-requisite it is mandatory to have External PSC for vCenter 6.0 environment to have Enhanced link mode.

There are few steps to be followed to reconfigure vCenter appliance from Embedded PSC to External PSC and I write this article with step by step instruction to reconfigure PSC.

Main Moto

16

Basic Requirements for Reconfiguring:

  • vCenter server appliance must be an Embedded deployment mode.
  • The Target platform services controller must be replication partner of the existing Embedded Platform Services Controller in the same SSO Domain.

My Lab:

  • 192.168.2.102 is my vCenter Server appliance with Embedded PSC
  • 192.168.2.103 is my External PSC which is my replication partner to existing Embedded Platform Services Controller.
  • There are many ways to perform this operation. I used cmsso-util to reconfigure my Embedded PSC to External PSC.

Steps

Login into vCenter appliance in shell mode.

Run the following command to reconfigure Embedded PSC to External PSC.

cmd

cmsso-util reconfigure –repoint-psc “<External PSC FQDN/ IP address>” –username “Administrator” –domain-name “<Domain name of your PSC>” –passwd “<Password for administrator>”

12

This successfully reconfigured to External Platform Services Controller.

Let’s take moment to validate the reconfiguration.

cmd

/usr/lib/vmware/vmafd/bin/vmafd-cli get-ls-location –server-name localhost

13

We are able to successfully see that it is reconfigured to new External PSC.

Validation:

We can also validate when we logged in into vCenter using WebClient or connecting to vCenter using shell

14

Validate through Shell

Step by Step process to deploy vCenter Server appliance 6.0 with Embedded PSC

Deploying Center server appliance 6.0 is totally different compared to vCenter Server appliance 5.5.

Let’s start our Step by Step process of deploying vCenter appliance 6.0

Step 1: 

Once you download ISO image of vCenter Server appliance 6.0 from vmware  page. We need to install VMware- ClientIntegrationPlugin to deploy (Path: ISOimage\VMwareVCSA\vcsa\VMware-ClientIntegrationPlugin)

1

Once Installation is completed we will proceed with next step

3

Step:2

Run vcsa-setup file which is under ISOimage\VMwareVCSA. The installation process will start from browser.

 

You can perform installation and upgradation using same ISO image

5

 

Step:3

Accept license agreement

6

Step:4

Provide IP address or FQDN of vCenter/Host you want to deploy your vCenter appliance.

7

Step:5

Proceed to trust SSL certificate

8

Step:6

Provide details of your Appliance which you want to build

8

Step:7

Select “Install vCenter Server with an Embedded Platform Services Controller”

10

Step:8

Provide SSO details and proceed with Next

11

Step:9

Select appliance size based on environment and proceed with Next

12

Step:10

Select Datastore and proceed with Next

13

Step:11

Configure Database and proceed, vCenter appliance only support embedded PostgresSQL database or External Oracle database. SQL server is not supported with vCenter appliance 6.0

14

Step:12

Configure Network settings of vCenter Server appliance

Note: create DNS A and PTR records before proceeding with this information

15

Step:13

Join Customer Experience Improvement Program (its your decision not a compulsion)

17

 

Step:14

All the configurations are done. Recheck the configurations and start installation

18
Wait until installation is completed.
19

Step:15

Once Installation is done You can connect to vCenter server using vami page https://fqdn or ipaddress:5480 and connect to vsphere-client to connect / manage ESXi Hosts using URL https://fqdn or ipaddress/vsphere-client

This is step by step process to configure vCenter Server appliance 6.0

Managing ESXi 6.0 U2 in Host-Client

We have flashy Host-client GUI to manage ESXi Host independently without the help of vCenter Server from 6.0 U2 vSphere Environment.

Let’s go through how to manage ESXI Host through host-client which is one of the new features in vSphere 6.0 U2.

To open ESXi Host in Hostclient 

  • Open ESXi Host https://FQDN or IP address.
  • Use “Open the VMware Host Client”Untitled

Login Page

  • Use root/ local user credentials to login ESXi Host1
  • You can find VMware Host Client documentation in the same page.

Home Page

  • There are tabs to manage/ monitor Host, the different tab for Virtual Machines, Storage, and Networking.2
  • You can find details of Hardware, Configuration, System Information and Performance in center page of ESXI Host host-client.5
  • Move cursor down to find Configuration and System Information details.6
  • further, move we could see performance summary of ESXi Host.7

Shortcuts Available

  • Enabling/ Disabling SSH and console shell is so easy
  • Go to Actions > Services > Enable Secure Shell / Enable console shell3
  • We have a shortcut to Enter strick/normal lock down mode.
  • Go to Actions > Lockdown mode > Enter strick/ normal lockdown4
  • We can generate support bundle instantly
  • To generate support bundle, go to Actions > Generate support bundle.8

Upgrading Embedded vCenter 5.1/5.5 to vCenter 6.0 in linked mode

Objective: vCenter 6.0 in linked mode is not possible with embedded PSC. To configure vCenter 6.0 in linked mode, the vCenter should be pointing to external PSC.

Find the recommended topologies here

In this article I explained step by step process to upgrade your existing VMware vCenter 5.1/5.5 to 6.0 in linked mode.
  • Deploy a new VMware vCenter Single Sign-On machine for VMware vCenter Server on PSC1
  • Deploy a second VMware vCenter Single Sign-On machine for VMware vCenter Server on PSC2
  • Repoint the VMware vSphere Web Client on vCenter 1 and 2 to their corresponding VMware vCenter Single Sign-On deployments
  • Repoint the VMware vCenter Inventory Service on vCenter 1 and 2 to their corresponding VMware vCenter Single Sign-On deployments
  • Repoint the VMware vCenter Server on vCenter 1 and 2 to their corresponding VMware vCenter Single Sign-On deployments
  • Remove VMware vCenter Single Sign-On installed on vCenter 1 and 2
  • Upgrade VMware vCenter Single Sign-On to an External Platform Services Controller PSC1 and PSC2
  • Upgrade VMware vCenter Server 5.1/5.5 on vCenter 1 and 2 to VMware vCenter Server 6.0

psc

Precautions:

  • Take backup of SQL database for all the vCenter. proper backup /snapshot of vCenter server.
  • Check upgrade path. To check upgrade path use the VMware Interop Matrix

Lets start our process

Note: I have deployed two vCenters named vCenter1 and vCenter2, New Windows machines for external SSO/PSC named PSC1 and PSC2 respectively. This article uses same names for upgrading vCenter 5.5 to vCenter 6.0

Deploy a new VMware vCenter Single Sign-On machine for VMware vCenter Server on PSC1

  • Deploy a new Microsoft Windows Server on a physical or virtual machine that meets the software and hardware requirements for your version of VMware vCenter Single Sign-On.
  • Check Build number of vCenter and use same build number ISO to install Single Sign-On.
  • To verify your build number check VMware KB article here
  • Once you are sure with build number Install Single Sign-On on PSC1

Note: When prompted, create a new VMware vCenter Single Sign-On domain. Do not join another VMware vCenter Single Sign-On domain or instance.

Deploy a second VMware vCenter Single Sign-On machine for VMware vCenter Server on PSC2

  • Install a new Microsoft Windows Server on a physical or virtual machine that meets the software and hardware requirements for your version of VMware vCenter Single Sign-On.
  • Follow the same instructions as mentioned above before installing Single Sign-On.
  • Install Single Sign on PSC2.

When prompted:

  • Select the deployment mode Multisite.

17

  • Enter the information to point to the partner VMware vCenter Single Sign-On node installed in the previous step, Deploy a new VMware vCenter Single Sign-On machine for VMware vCenter Server on PSC1.
    • Enter the partner host name.The partner host name is the IP address or DNS name of the existing VMware vCenter Single Sign-On server to replicate from.
    • Enter the password for the VMware vCenter Single Sign-On administrator account of the existing VMware vCenter Single Sign-On server.

18

  • Review and accept the partner certificate.
  • Enter the new site name.
  • Accept or change the HTTPS port for VMware vCenter Single Sign-On.
  • Accept or change the default VMware vCenter Single Sign-On installation folder.
  • Review the installation options and click Install.
