Comment # 9 on bug 1162435 from John Wolfe

The LSI Logic Parallel SCSI controller on PCI bus 0 is what has triggered this
problem.  For this controller, no "label" file is created for the disk device
in the /sys/class/block tree when the controller is on PCI bus 0.  This would
also happen for the (deprecated) BusLogic SCSI controller.  This is not the
case for other supported controllers.

We will need to special case this particular hardware configuration to mark
that it is SCSI controller SCSI0.   That fix will be targeted for the next
major release of open-vm-tools.

In the meantime a patch to change the warning message to a debug level message
(as mentioned in comment 2) is being prepared for open-vm-tools 11.0.x.
