I’ve just seen this in the release notes for VMware vCenter Server Appliance 6.7 Update 1b:

Removing a virtual machine folder from the inventory by using the vSphere Client might delete all virtual machines


In the vSphere Client, if you right-click on a folder and select Remove from Inventory from the drop-down menu, the action might delete all virtual machines in that folder from the disk and underlying datastore, and cause data loss.

This issue is resolved in this release.

I’ve just checked this in my lab on the 6.7 U1b release – when I delete a VMfolder with a VM inside – the VM gets removed from inventory but not deleted on the datastore!

If I delete a VMfolder containing a VM, in vCenter 6.5 the VM gets deleted in the datastore!

Be careful when deleting virtual machine folders!

A couple of days ago I was visiting a customer to setup their Lenovo host to run vSAN – after the initial setup of vSAN kernel IPs, disk groups and so on, I took a look at the “VSAN Health check” to make sure that everything was healthy and supported.

Under the “hardware compatibility” part all checkmarks where green, but the Controller firmware version was not detected – so I did found it a bit strange that it reports the disk controller as supported without knowing what version it actually was running.


This issue is not new to me, as I have seen it a couple of times before, but this time it was different after all.

This morning I faced a strange issue in my vSphere Lab when a wanted to login to VAMI interface – of course to install the newly released “vSphere 6.7 U1” update.

I opened the VAMI URL for my Platform service controller (PSC): https://<FQDN>:5480 and typed in my root credentials as a normally would. However, the only thing that showed on the screen was a message saying: “Unable to login”.

After this I tried to type in my password multiple times to make sure that I was actually typing in the correct one, but still, I just got the same error message.

So, you find yourself in a situation where you have lost the root password for your ESXi host(s). Luckily there are multiple ways of resetting it – but the best method depends on the exact situation. Ill try to outline three different scenarios (of course, more exists) – maybe your are placed in a completely different scenario but maybe this post can help you anyway.
