DBCC loginfo

I've been using this useful undocumented DBCC command
recently but the only information I can find on the Status
column it returns, is that above 0 means that the virtual
log is in use.
Now all the VLF's I examined had a status of 2 and these
we're not uncommitted or undistrubted, just not backed
up. These returned to a status of 0 when backed up.
So, does anyone know what the values in the Status field
mean? How is say 1 different to 2? What other values can
it take?

DBAI think a value of 1 is the VL that SQL is currently writing to, 0 is the
inactive part of the log and 2 is the active part of the log... Only the
inactive part of the log can be shrunk away...
BTW, this is undocumented and these are just my observations ( which may be
incorrect.)
