vRealize Automation Upgrade Guide from version 7.3 to 7.4

Updated: Apr 2, 2019


I shall be sharing a comprehensive guide for upgrading your existing vRealize Automation 7.3 to 7.4

Let's start by describing my environment. I have setup a 3 node vRealize Automation distributed deployment.

Environment

vRealize Automation Appliances ( using an embedded vRO )

vraapp01.pslab.org, vraapp02.pslab.org and vraapp03.pslab.org

IAAS Nodes

iaas01.pslab.org : Database , Website , ModelManagerData , ModelManagerWeb , ManagerService , ManagementAgent , DemOrchestrator and WAPI

iaas02.pslab.org : Website, ModelManagerWeb , ManagerService , ManagementAgent , DemOrchestrator and WAPI

iaas03.pslab.org : Management Agent , DEMWorker and vSphereAgent

iaas04.pslab.org : Management Agent, DEMWorker and vSphereAgent

lb aliases

vRA : vrava-lb.pslab.org

IaaS Web : iaasweb-lb

IaaS Manager : iaasmgr-lb

Health-checks before upgrade

You have to ensure environment is healthy before you start an upgrade of your infrastructure

1. Let's start by checking cluster "Last Connected" status, This IaaS nodes should have last connected time not more than 30 seconds. Appliances should not be more than 10 minutes.

Take an ssh to Master/any other vRA appliance and then execute following command

vcac-config cluster-config -list | sed -e 's/[{}]/''/g' | awk -v k="text" '{n=split($0,a,","); for (i=1; i<=n; i++) print a[i]}' | grep -E 'nodeHost|lastUpdateRelative'

This is how it's output would like


2. Verify if rabbitmq cluster status is intact by running below command

rabbitmqctl cluster_status


Ensure all three vRA appliances are available under running_nodes section

cluster_name is set to current MASTER node and there are no partitions ( should be blank as above )

3. Verify IaaS service hosted in Microsoft IIS is running

  • Start browser and enter URL https://webhostname/Repository/Data/MetaModel.svc to verify that Web Repository is running. If successful , no errors are returned and you see a list of models in XML format



  • Log in to the IaaS Website and check that the status recorded in the Repository.log file reports OK. The file is located in the VCAC home folder at /Server/Model Manager Web/Logs/Repository.log

iaas01


iaas02


  • Start browser and enter url https://IaaS-Web-FQDN/WAPI/api/status/web , the service must be "REGISTERED" in the output



  • Verify Iaas Manager Service https://IaaS-Mgr-FQDN/VMPS2Proxy


4. Ensure all Prerequisites for upgrade vRealize Automation are met

5. Follow Checklist religiously

  • Run NSX and Security Data collection

  • Backup existing vRA environment ( It's a MUST )

  • Change database replication mode to "ASYNCHRONOUS" to disable automatic failover

  • Download vRealize Automation updates from repository or use iso image

  • Disable Load balancer

Note : In my environment, I have configured NSX Load-balancers. I have it disabled at the moment , see the below screenshot


and I am using CNAMES in AD for LB purposes till upgrade is complete. These would be pointing to the primary node


6. Backup vRA database ( vPostgres ) by following KB

7. Backup IAAS database (SQL) with the help of your DBA

Download vRealize Automation 7.4 update repository from VMware Downloads

Note : Take snapshots before you upgrade , Ensure there are no In-Progress or Stuck request. If there are any then wait till they finished or clean them up

Let's kick off upgrade now. We will be performing an upgrade with IAAS nodes inclusive or excluding IAAS nodes

Identify your current Master node among all three appliances and mount ISO image to it

In my case it was vraapp01.pslab.org as seen in the screenshot below



Now go back to VAMI and under Update tab change Settings to Use CD-Rom updates and click on Save Settings


Now go back to Status tab under Update and click on Check Updates. Appliance should detect the ISO mapped to it and then show it under Available Updates


Now that we have everything ready let's press Install Updates and start the process



Under /opt/vmware/var/log/vami/ we can see that the installation is proceeding in background once it started


installer-page.log is something we can monitor while this upgrade is in progress , it's available under

/opt/vmware/var/log/vami/


Another log to monitor is updatecli.log under same path


For a change upgrade did fail on second node ( vrapp02.pslab.org ) , it did upgrade Master ( vraapp02.pslab.org ) and third node ( vraapp03.pslab.org )


As stated under this document reverted the snapshot and updated iso image and started upgrade on this node , vraapp02.pslab.org again

After a while , even this node upgrade is now complete



Then verified that all nodes were in cluster


After verifying cluster status , went ahead and executed reboot on the master node


As stated in the documentation , rebooting MASTER will automatically reboot it's peers


As soon as MASTER node is back after rebooting it's peers and all services are started , we would see IAAS upgrade being kicked off.


Above information can be reviewed in /opt/vmware/var/log/vami/upgrade-iaas.log as well

As stated earlier all of the upgrade were going as expected


Finally , it states that the upgrade is now complete


Now that the upgrade is complete , let's perform a quick health check

Last Connected status looks good


Services on all of the nodes were registered as expected. So no failures observed here. I am showing only the MASTER node screenshot below.


Performed checks on IAAS as well , all of them passed with flying colors


No Errors in repository.log as well. Since every check has now been cleared.

Now it's time to enable NSX load-balancer back . As a first step, I would go ahead and remove the CNAMES configured on my AD


Re-create entries for your LB VIP's


Let's go back to NSX and enable virtual servers


Once we enable virtual servers , we see pool and member status changed to UP as well. Which is what we look for


Once all the checks from LB perspective are now completed. It's time to login into vRA 7.4 . As you can see we are using LB VIP , not a individual node anymore.



That's it. This concludes article on upgrading your vRealize Automation to 7.4

Leave your feedback and do not hesitate to ask questions.

!!! Happy Learning !!!
