vmx - GuestInfo: Failed to convert UUID 'CK M0 xx xx xx xx xx   ' to binary

Environment

Cause

Pass-through RDM disks are not supported by VM Guest Info's 'Disk Info' feature.

To do so, add the following lines to the VMware Tools tools.conf configuration file:

[guestinfo]
disable-query-diskinfo=true
