Thanks for the info. We don't really have issues with the .vmdk files themselves.
It's more when we need to expand/increase the size of the virtual disks for the Guest and you have like 5 or more that may be the same size, so you have to do some investigating as to which disk is what in the OS.
Vs. a physical machine, we'd know quite easily via our SAN tools since each LUN is different and/or the WWID # is different so it's very easy on the SAN to know which disk you're expanding, but not so much in VMware.
Would be a nice enhancement request, I guess.
