Sun Unix, access to one file from different machines at the
same time. If only read that file, is there any possibility that
data read could be wrong due to this simutaneously accessing mode?
I think it should be no problem, just wanna make sure. Thanks in
advance.

one hard drive can't read two different nodes at the same
time.
so there is no "simultaneous".
that's why highly visited server had better use RAID,
because a lot
of hard drives might work really simultaneously.
