I have vmware-vSphere-CLI-5.5.0-1292267 installed on vMA 5.5.0 BUILD-1295338, and it looks like the vmkfstools perl script does not create vmfs5 file systems. The perldoc only refers to vmfs3, and I get an error when I specify vmfs5: "Unable to create vmfs: A specified parameter was not correct"
The vmkfstools installed on our ESXi hosts is not Perl, it is a binary, and it looks like it does support vmfs5. So, does this mean we can't use the CLI to create vmfs5 datastores?
