It's likely related to the mass storage being VMware in both cases. Basically, it's saying that it tried to execute a SCSI command called
WRITE SAME which is used to write the the same block of data over x number of consecutive disk blocks. It's usually used to zero particular regions on a disk.
If the actual zero'ing operation doesn't fail then the biggest problem here is that the OS has to manually say "ok now write this block of zeros here" etc, etc until the zero'ing operation is done. That may increase bandwidth to and from storage for the duration of the zero'ing operation. That's not a hugely common operation for most workloads so you may just ignore it.
If it is causing a problem for you, you'd have to check with a VMWare resource to figure out what you need to do to get
WRITE SAME to be supported by the VMWare disks.
