Thanks @acortiana ,
The docs say "The RefreshStorageSystem method also performs a VMFS rescan."

http://pubs.vmware.com/vsphere-6-5/index.jsp#com.vmware.wssdk.apiref.doc/vim.host.StorageSystem.html#rescanVmfs

So refresh should actually take care of this, does it not? Or is there another reason to use RescanVmfs directly? And maybe we could mention the reason(s) in the help doc or just a comment.

Would also prefer the flag to be named rescan-vmfs rather than rescanvmfs, ok with you?

[acortiana]

You are right, Doug. RefreshStorageSystem also performs a VMFS rescan.
I implemented this feature because I didn't know this.
Maybe this feature can be useful: in the GUI it's possible to do a VMFS rescan by itself and I think that this is faster than doing a full RefreshStorageSystem call.
No problem for the name of the flag: rescan-vmfs is ok.

@acortiana ok sounds good, I didn't know the GUI had that option. If you can just rename the flag that'd be great.

Thanks @acortiana !
