If that UNIX is Solaris 8, be prepared to fskc some
filesystems
manually when you power it back on. Even on my FreeBSD box and older
Sun 4 that's running Solaris 2.4, both of which tend to come back up
without any problems after a power failure, I still try to do a proper
shutdown and halt... and yes, I still issue three sync commands before
halting the system. Laugh at this superstition if you want to, but
doing that on my Ultra running Solaris 8 seems to be the only way to
get it to prepare it for powering off so that I don't have to do a
manual fsck that prompts me for a lot of repetetive questions.
NetBSD and OpenBSD boxes seem to boot fine, albeit slowly.
Anyway, to those running UNIX systems who are used to
PeeCees running
simpler operating systems and software, a word of advice: UNIX systems
often have many processes running, some of which very well may be in
the middle of writing to your hard disk when you switch the system off
without a proper shutdown... particularly if you've got lots of things
running like a database, have lots of cron jobs, have Apache running,
etc. But, if you enjoy flirting with disaster and have good
backups...
So what if they're writing to disk? If they have proper file systems that
won't really matter. Mind you, at least I always check that the drive lights
aren't on.
