  • 1.  Writing via SAN

    Posted Nov 02, 2009 01:32 PM

    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?

    The backup guide has some example code - we are working on an expanded sample to show some of these capabilities.

    To answer your other question, SAN does need a snapshot because of an implementation quirk. Writing via SAN is supported.

    Thanks
