T10 have now dropped the LID1 and LID4 stuff (its the length

commands.
Obviously LID1 based XCOPY support is important for backward
compatibility (back to SPC-2) but for the future maybe you might
consider adding the equivalent LID4 support for a basic XCOPY.
For example it means using the 3PC VPD page instead of the
RECEIVE COPY RESULTS(operating parameters) command. I believe
FreeNAS now supports both LID1 and LID4 variants of a basic
XCOPY (plus a restricted version of ODX without snapshots).
Hi Doug,
I was trying to learn more about ODX and saw this page:
http://msdn.microsoft.com/en-us/library/windows/desktop/hh848056%28v=vs.85%29.aspx
but it just muddied the waters for me. Is ODX proprietary to MS, or is
it XCopy lite, or what? And what's the difference between xcopy lite and
LID4 XCOPY?
Thanks -- Andy
