VMware ESXi was preinstalled on system:
Username: root
Password: <Services Tag> + “!”

The first problem on VMware is you can’t create a datastore, got error “Cannot change the host configuration”.

  1. start a SSH session using Putty to the ESXi server
  2. Show connected disks
    command: ls -lha /vmfs/devices/disks
  3. search for the disk size which is the same as the disk you want to create the datastore on. In my case the id  was naa.6d0946604530ba002222fdc313539238
    Make sure to use the correct id! Otherwise you might wipe out the SD-disk on which ESXi was installed
  4. Then type in this command
    partedUtil setptbl /vmfs/devices/disks/<id of the disk> msdosin my case it was

    partedUtil setptbl /vmfs/devices/disks/naa.6d0946604530ba002222fdc313539238 msdos
    (The output from this should be similar to msdos and the next line will be o o o o)

  5. Then in the vSphere client I was able to create the datastore
