If you are going to create the VMFS partition on the some mew local hdd or hardware raid volume, you can get in trouble with a message “Failed to update the disk partition information”. The reason for it is a broken/missing dos label on the device.
Create a new label
- Type Alt+F1 on the physical ESXi console
- Type “unsupported” and after a password prompt your root password
- Identify your device with
esxcfg-scsidevs -l | less- note the Devfs path of the output above, and start fdisk
fdisk <<here the devfs path, something like /vmfs/devices/disks/...>>- type “o” “Enter” “w” “Enter”
- type “exit”
- Go ahead and try again to create VMFS volume, it should work now
