I'm able to read via LAN and SAN using the VDDK. I'm also able to write via LAN. I cannot write via SAN.
The docs are pretty vague on this (by which I mean non-existent), and there is no example code. It's not clear at all what parameters I would use to open the disk for writing since using the SAN requires a snapshot, but shouldn't a snapshot be readonly? What kind of sense would it make to have a snapshot which can be written?
Is writing via SAN even supported?
