I have just installed VMWARE ESXi5 on a physical server with 2 hard drives. OS on one, Virtual Machines will be on the other. I have the vmdk's I want to use on a usb disk. How do I copy them from the USB disk on to the local disk???
Simplest, most supported and safest way is to plug the USB disk in to your own computer, and then use VMWare console to access the datastore browser and upload the files there.
enable ssh/scp access and then use scp client [like winscp] to copy the files.
how to enable it: here.
