Hello,
at first I want to say sorry for my bad English. I hope I am able to express my problem understandable.
I have seen a lot of ESX hosts, most of them are ESX 5, 5.5 and 6. Nowhere it is a problem to increase disk capacity while the VM(s) is/are running, when there is no snapshot.
Now here are two ESXi 6.5 without the possibility to expand disks when the VM is turned on. We are using a SCSI Controller and no, there are no snapshots. To be sure there is nothing I created a snapshot for every virtual machine and deleted it again.
Even when I create a new SCSI oder SATA Controller and using a new disk I am unable to increase the size without turning off the machine.
When the machine is turned off I am able to do what I want.
The disks are provided by thin provisioning. Reinstalling the VMWare tools did not help.
The size is simply grayed out like we know it from machines/hosts with existing snapshots. I am sure there is a simple error. Are you able to help me?
I would be very grateful.
Thank you very much.Have a nice weekend!
