Well, how many times during ESXi upgrade have you checked where the ESXi is installed? either you know where the ESXi is installed or you think you know, I have to share with you very frustrating story that I have heard from my American fellow, three weeks ago, a customer purchased a new license and decided to upgrade VMware ESXi by himself and not purchasing professional service for completing VMware project.
In fact, he wanted saving bank hours of service which makes sense to everyone, As most of us know the upgrade process it’s really not a complicated task.
So he got the ESXi disk installation and inserted the disk to the physical server, totally he has 3 disks in, the phase of selection where the ESXi is installed he has selected the wrong disk, he chose different disk which was the corporate file server, he thought that particular disk does store the ESXi installation.
VMware knows to warn us for the re-partition disk and you should confirm it, despite it, he proceeded with F11.
If it recognizes any existing VMware installation, was getting “ESXi and VMFS Found“:
The message you should get during ESXi upgrade:
He didn’t notice to that and proceed the new ESXi upgrade installation. the File server wasn’t available and recovery commands were
* Regarding backup, turned out that it wasn’t backed up daily, just once a week on Saturday, and he completed the task on Thursday.
What are the conclusions?
- 1) Don’t you know something? don’t hesitate, raise a flag and consulting with an Experts!.
- 2) File server must be backed up daily!.
- 3) Check where ESXi is installed before inserting Disk installation.
- 4) Read the VMware instruction during an upgrade.

Click on “Storage” and select the “Device View“:
By going over the “Datastore” you can find the following Partition details which presenting you the VMware partition structures, according to the size, partitions and the name you can realize that the ESXi is installed there:
