A general controller error occurred. Connection refused while powering on virtual machine

Recently I had an issue where I was trying to power on a VM from vCenter but unable to power on.
While powering on getting below error.

A general controller error occurred. Connection refused.”

VCenter server which Im running is 6.0 and on appliance (VCSA).

Steps I follow to resolve the issue:

While investigation I found it’s a issue of Workflow manager service which was causing VM to start from vCenter. However, I was able to power on the VM from ESXi, which shows that the issue is not with VM or ESXi . It’s the issue with the services of workflow, which are not allowing VM to poweron from vCenter.

I tried below steps to verify the status of the VMware vCenter Workflow Manger service from VCSA.

1) Login to VCSA via Putty.
2) shell.set --enabled True
3) service-control --status vmware-vpx-workflow
Status of the services was showing stoped, So, I tried to start the service by using command.
service-control --start vmware-vpx-workflow.

I was getting error while starting the workflow services.

Now I tried to verify the disks space of VCSA by using df –vdf. Where I found that the space is about to 100% at /storage/logs disk. Removed the unwanted data from this location and make some space to breath.

Later I again try to start the vmware workflow services and its started successfully and by that VM from vCenter was able to poweron without any issue.

Happy Sharing.... :)

VM Creation Date & Time from Powercli

Most of the times we have several requirement when we talk about IT environment like designing , deployment , compliance check or for Security auditing the environment. Somewhere during security auditing we require to provide several information to security team to get successful audit. One of them is the compliance of Virtual machine auditing of creation date and time. Here into this post we will explore how to get the creation date and time of virtual machine hosted into the vCenter or ESXi. To get the details we will use VMware Powercli to extract the details. By default there is no function added into Powercli to get such details, so here we will add a function of vm creation date. Below is the function which needed to be copy and paste into the Powercli. ======================================================================= function  Get-VMCreationTime  {     $vms  =  get-vm     $vmevts  = @()     $vmevt  =  new-object  PSObject     for

Unable to poweron the VM. (Failed to lock the file)

I have encountered may issues like where after some upgrade or migration we were unable to power on the VM. Figure 1 An error was received from the ESX host while powering on VM HSSVSQL01. Failed to start the virtual machine. Cannot open the disk '/vmfs/volumes/578d835c-18b2c97a-9b0d-0025b5f13920/SAMPLE1_cloud/000000.vmdk' or one of the snapshot disks it depends on. Failed to lock the file In above Figure:1, where while powering on the VM, its prompt for an error. Well, there are several reason for where the VM unable to poweron and you can find many article on this. Here in this article we will discuss to resolve this issue. Please use below step to resolve the disk lock issue  C hecked that VM is running on snapshot if its getting error " VM Consolidation required". Checked the snapshot manager if its showing any snapshot. If yes, try to delete the  snapshot.
