As in, it salvaged everything automatically when it came back up, or
volumes were not attached when it came back up, and you needed to
salvage to bring them online?

Well, why are they not attaching? FileLog should tell you. And the
salvage logs should say what they fixed, if anything, to bring them back
online.

Also, salvaging an entire partition at once may be quite a bit faster
than salvaging volumes individually, depending on how many volumes you
have. The fileserver needs to be shutdown for that to happen, though.
