Re: [Veritas-bu] REQUIRED_INTERFACE, anyone using private backup networks?

I’m with Rusty on this. We have been
using a separate backup LAN for a few years now and have never used
REQUIRED_INTERFACE. We simply set a backup host name (e.g. if primary is
myhost then backup is myhostb) and add that to /etc/hosts on master and add the
backup LAN IP for the master to hosts on the individual servers.
In the recent issues we had with host name
resolution one of the first recommendations we got was for using
REQUIRED_INTERFACE but I resisted that mainly because I wasn’t sure what that
would do to the separate interface we use to connect to our Dedupe
appliances. As seen in that thread (bpclntcmd on hp-ux) the resolution had
nothing to do with use of REQUIRED_INTERFACE. If you’re being pushed to do
this by support you might want to push back.

REQUIRED_INTERFACE,anyone using private backup networks?
I've never liked
REQUIRED_INTERFACE as it seems to be problematic. Perhaps it's just me. Most of
our NBU servers have at least 3 networks (backup network, mgmt network and
metadata/intra-nbu network). We use multiple host file entries with the
different interface names and corresponding entries on the client. We also have
to put the proper SERVER entries in place. It's probably more complicated but
as long as these entries don't get messed with, all works perfectly. My point
is perhaps this type of solution could work for you.

[Veritas-bu] REQUIRED_INTERFACE,
anyone using private backup networks?

Anybody
have working experience on the "require_network" or
"required_interface" functionality?
Our clients/media servers have a private network
to traverse. Master is not connected (different site) however...v7.1.
Thanks!
