Came across a bug in version 7.5 where unneeded and unused business groups which no longer exists in vRA , still show up under deployments tab Created two business groups bgone and bgtwo in my lab. As you can see they are dummy or unused ones Logout and Login to see them under filters section of Deployments tab Expectation would be that after deletion of these business groups you should not see them under filters anymore But they would still be present This issue is fixed in upcoming release of vRealize Automation 7.x Any Business Group that is ever created remains forever in the cat_subtenant table. To ensure stale entries are deleted , we have to execute this script mentioned below which would delete old business groups and all foreign keys that has to be removed to be able to remove old records from cat_subtenant table Remediation Plan Postgres Backup is MANDATORY Using WinSCP copy pg_delete_DELETED_business_groups.sql script to /tmp of MASTER Postgres node SSH to the MASTER Postgres node and run the following commands cd /opt/vmware/vpostgres/current/bin ./psql -d vcac -U postgres -f '/tmp/pg_delete_DELETED_business_groups.sql' 2>&1 | tee '/tmp/pg_delete_DELETED_business_groups_OUTPUT.txt' Once above commands are executed , logout and close the browser. Clear Cache. Open a new browser and login into vRA Go to Deployments and filter section , you should not be able to see any unused and unneeded business groups anymore. Only valid ones would be available under this criteria Click Here for Script and Readme zip file

Use this script below to replace ESXi 6.5 and later version of host certificates seamlessly When you have vSAN cluster, network partition can occur and vSphere HA configuration could fail due to known issues documented under KB 52567 This script will take care of it. Make sure to create a directory /certs and save rui.crt and rui.key (New cert/key) before running the script Copy the script or content to /tmp Take chmod 777 – execute rights Execute the script /tmp/esxi_rplc_cus_certs.sh Disclaimer  : This will restart hostd / vsanmgmt agents. No effect on vSAN. hostd restart is tricky if there are underlying storage issues Click here for script

We recently stumbled upon an issue where database server had to be restored a date where it was working as expected after patching somehow screwed it up. Admins were able to connect to that server which was hosting vRA's IAAS database and take a backup of it After Server and DB was restored , IaaS service under VAMI wasn't coming back to "REGISTERED" state When we browse to component registry , we get following exception 2019-07-25T11:16:25.042+08:00 https://vra-web/WAPI/api/status Exception during remote status retrieval for url: https://vra-web/WAPI/api/status.

This gave us a clue that there might be a trust issue between the SQL server and the domain it's part of Verifying Group and User memberships confirmed this to us , yea the relationship was broken. AD account login to SSMS and the server itself was broken. As remediation task , we had to remove the node and then bring it back to the domain. Post that AD login to SSMS and the IaaS service was immediately registered

This blog article would talk about various services being offered by AWS AWS Global Infrastructure AWS Region & Availability Zones Each region is a separate geographic area. AWS Region has multiple, isolated locations known as Availability Zones. An availability zone is a datacenter Edge Locations Edge Locations are endpoints for AWS which are use for caching content. Typically this consists of CloudFront, Amazon's content delivery Network ( CDN) There are many more Edge Locations than Regions Compute Services EC2 : Stands for Elastic Compute Cloud. These are virtual machines inside AWS platform EC2 Container Services Run and Manage docker containers at scale Elastic Beanstalk Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS Lambda AWS Lambda is a server-less compute service that runs your code in response to events and automatically manages the underlying compute resources for you. You can use AWS Lambda to extend other AWS services with custom logic, or create your own back-end services that operate at AWS scale, performance, and security. Lightsail Lightsail is a lightweight, simplified product offering -- hard disks are fixed size EBS SSD volumes, instances are still billable when stopped, security group rules are much less flexible, and only a very limited subset of EC2 features and options are accessible. Batch Used for batch computing in cloud STORAGE SERVICES S3 Oldest Storage Services. Simple Storage Service commonly referred to S3. It's Object based Storage. User's upload their files into buckets. EFS Elastic File System , basically a Network Attached Storage, users can store their data into EFS volumes and map/mount them to multiple EC2 instances or virtual machines. Glacier Used for data archival. Snowball Used to migrate large amounts of data to AWS datacenter. Storage Gateway Virtual Appliances which we install in our on-premise datacenter which would replicate data to AWS infrastructure. DATABASE SERVICES RDS Relational Database Services ( MySQL , Aurora , SQL , Oracle ) DynamoDB Non-Relational database services ElasticCache Fully managed in-memory data store and cache service. RedShift Service used for Data Warehousing or Business Intelligence. MIGRATION SERVICES AWS Migration Hub Tracks user's applications as it's being migrated to AWS. Application Discovery Service Learns what applications we have and discover's it's dependency as well. Database Migration Service Easy to migrate database from On-Premise to AWS. Server Migration Service Migrate Physical and Virtual On-Premise servers into AWS. Snowball Write large volumes of On-Premise data into physical volumes and then send it to AWS NETWORKING AND CONTENT DELIVERY VPC Known as Virtual Private Cloud. It helps you create Firewalls , Availability Zones, Network Cider Address Ranges , Route tables and ACL's CloudFront Amazon's content delivery network Route 53 DNS service API Gateway Create your own API for service integrations Direct Connect Direction connect to transfer data from On-Premise to AWS datacenter DEVELOPER TOOLS CodeStar Cloud-based service for creating, managing, and working with software development projects on AWS. You can quickly develop, build, and deploy applications on AWS with an AWS CodeStar project. An AWS CodeStar project creates and integrates AWS services for your project development toolchain CodeCommit Stores code which is developed into private repository CodeBuild Once code is ready, this service would compile for you and would make it ready for deployment CodeDeploy Used to automate application deployments CodePipeline Continuous delivery service to model , visualize and automate application releases X-Ray Debug service to analyze and troubleshoot to find root-cause of issues and identify performance bottle-necks

When you browse directories in vRA UI and click on Sync Log , are you seeing a message stating ! Error searching for Sync Results from storage This could happen if elasticsearch service on your Master / Sync Replica/ Potential Replica is "not running" as expected. Elasticsearch is only used for Sync log in vRA Login into each of your vRA appliances and execute command to verify status of elasticsearch service elasticsearch status If Status says "Not running (but PID file exists)" Restart elasticsearch service and see if it helps `service elasticsearch restart` If the above step fails then you could try Removing the PID rm /opt/vmware/elasticsearch/elasticsearch.pid Start the service - service elasticsearch start Above steps should help you fix the problem. You may also perform following health check to verify if elasticsearch on all the nodes are in healthy state ssh to each appliance and then execute below command curl -k http://localhost:9200/_cluster/health?pretty=true #vRealizeAutomation

Follow below steps to successfully increase existing partition size of /storage/log of a vRealize Automation appliance Pre-Requisites Full backup or clone of vRA nodes This activity must not be performed during business hours or weekdays. Downtime has to be taken and perform under a scheduled change Note : If you have a HA setup, then start this activity on a secondary nodes Procedure Select vRA appliance using vSphere Client and add an additional disk I am adding a 20 GB disk for this example Run df -h and make a note of existing /storage/log partition name , if you go by defaults it must be /dev/sdb1 Run this command to manually scan for a new device echo "- - -" > /sys/class/scsi_host/host0/scan Check if new disk is seen in the VM by running command "dmesg" Run fdisk /dev/sde (considering /dev/sde) and start recreating the partition following the example shown in the screeshot Once above step has been completed , execute command " partprobe " , This would commit any changes made to kernel Now create a filesystem executing mkfs -t ext3 /dev/sde1 ( In my case it's /dev/sde1 , it might vary if you have added additional disks to vRA appliance previously ) Execute following command mkdir /tmp/log/ mount -t ext3 /dev/sde1 /tmp/log/ df -h Stop all services using commands vcac-vami service-manage stop vco-server vcac-server horizon-workspace elasticsearch service vpostgres stop Then execute cp -a /storage/log/* /tmp/log cd / mount Post that execute command sed -i -e 's#/dev/sdb1#/dev/sde1#' /etc/fstab (Make sure you use the correct Filesystem here) Now reboot vRA appliance Validate /storage/log partition once and check if application logging is working as expected !! Hope this helps !!

Came across a problem recently where provisioning and reconfiguration of virtual machines through vRealize Automation were failing Exceptions seen in catalina.out 2019-06-02 09:53:25,643 vcac: [component="cafe:event-broker" priority="INFO" thread="event-broker-service-taskExecutor8" tenant="" context="" parent="" token=""] com.vmware.vcac.core.event.broker.integration.PublishReplyEventServiceActivator.onApplicationEvent:96 - Message Broker unavailable[internal stop] 2019-04-02 09:53:25,711 vcac: [component="cafe:console-proxy" priority="WARN" thread="Grizzly(1)" tenant="" context="" parent="" token=""] com.vmware.vcac.platform.event.broker.client.stomp.StompEventSubscribeHandler.handleException:493- Error during message processing: session:[f4329ebb-4e2e-7690-8b6a-3f420c8bd226], command[null], headers[{message=[Connection to broker closed.], content-length=[0]}], payload [{}].

Above exceptions clearly state the problem is with messaging broker which is rabbitmq Performing rabbitmq reset's and then adding second or third node ( if available ) to the master would eventually resolve the problem. After fair bit of research under rabbitmq logs we see on node psvra01.nukescloud.com: =INFO REPORT==== 11-Jun-2019::16:31:41 === rabbit on node 'rabbit@psvra03.nukescloud.com' down =INFO REPORT==== 11-Jun-2019::16:31:41 === Keep rabbit@psvra03.nukescloud.com listeners: the node is already back on node psvra03.nukescloud.com: =INFO REPORT==== 11-Jun-2019::16:54:12 === rabbit on node 'rabbit@psvra01.nukescloud.com' down =INFO REPORT==== 11-Jun-2019::16:54:12 === Keep rabbit@rabbit@psvra01.nukescloud.com listeners: the node is already back ... =INFO REPORT==== 11-Jun-2019::18:55:09 === rabbit on node 'rabbit@rabbit@psvra01.nukescloud.com' down =INFO REPORT==== 11-Jun-2019::18:55:09 === Keep rabbit@rabbit@psvra01.nukescloud.com listeners: the node is already back Above snippets clearly show network partitions / issues happening. Rabbitmq does not tolerate network partitioning events and does not recover from them properly. Executing below command would help in somewhat resilient in case of these network partitions rabbitmqctl set_policy ha-all "" '{"ha-mode":"all","ha-sync-mode":"automatic","ha-promote-on-failure":"always","ha-promote-on-shutdown":"always"}' New versions of vRealize Automation have mechanisms in place to detect this sort of issues and attempt an automated recovery The command mentioned above will help to certain extent but there has to be 100% available and redundant network available between vRealize Automation nodes.

Reconfiguring a virtual machine managed by vRealize Automation fails with an exception stating "The data specified within the request is invalid.The number of nics you requested are more than specified in the blueprint that was used to provision this machine" In vRealize Automation 7.5 , when any Day-2 actions are performed ( Change of CPU / Memory , Network etc.. ) , the network size is always checked against the blueprint maximum allowed for the VM. Above exception is thrown when a given VM has more than the maximum nics allowed. vRA will not allow the max nics to be exceeded at any point in time. Even when vRA is not performing any Day-2 action on the nics , it still performs the network size check and throws an exception. This behaviour has been changed in vRealize Automation 7.6 In this version a network check is ONLY performed when a network change is being performed through Day-2 actions. If other attributes are being changed other than networks then the network size check wouldn't be performed.

After upgrading vRA from 7.5 to 7.6 , following services might show up as unavailable advanced-designer-service - UNAVAILABLE o11n-gateway-service -UNAVAILABLE shell-ui-app - UNAVAILABLE vco - null Going through logs you might see following exception com.vmware.o11n.sdk.exception.RestApiException: com.vmware.o11n.service.version.ContentVersionException: org.springframework.dao.IncorrectResultSizeDataAccessException: query did not return a unique result: 2; nested exception is javax.persistence.NonUniqueResultException: query did not return a unique result: 2 To resolve, check the vmo_contentversioncontrol table in vRA's Postgres database to see if there is a duplicate __SYSTEM record. if so, remove the one with id = 2 This is how that table should look Once the second id is removed , services should start properly.

After installing vRA 7.5 HF5, it is not possible to install any additional IAAS components - e.g. proxy agent / DEM. Attempt to launch the installer fails: Error: "A newer version of the product is already installed on this machine". This is due to updated proxy agent launcher to version 7.5.0.16144 in HF5. "C:\Program Files (x86)\VMware\vCAC\Agents\\VRMAgent.exe" Since it is only the launcher - the "add remove programs" is not updated with this info. To workaround this problem Take a snapshot of IAAS machine Take a backup of file "C:\Program Files (x86)\VMware\vCAC\Agents\\VRMAgent.exe" From VRA Appliance master node - download file: /usr/lib/vcac/patches/repo/contents/vRA-patch/f759789753d68625f0136e9bfe159b19c4607b4cebf06566c4cf6c43fa5b4b5b/patch-vRA-7.5.9501892.12933355-HF5-Reverse/vcac/components/iaas.net/build/bin/Release/legacy/VRMAgent.exe Stop "VMware vCloud Automation Center Agent - " service in IAAS Replace the VRMAgent.exe file Install a new vSphere Agent Replace the VRMAgent.exe with the backup file taken in step 2 Start the service Now attempt to install DEM/Proxy agent it should work as expected
