How long can hostname be? 1

[Blizard]

I am trying to find what the maximum length is for an AIX hostname - just the machine name without domain info. We currently use 8 characters, but I am building a new data center and the way we are configuring the machines, an extra character or two would be very helpful.

We chose 8 characters several years ago, but I can't remember why. It might have had something to do with the HP systems we have.

Any info gratefully accepted.

Help screen in smit (F1 when in "smit mkhostname") talks about 32 chars or less for compatibility with older hosts, so you shouldn't get in any trouble...
