This was a big problem for us. It stopped us using clients >7.1.
The server still worked (provided there was no client with the
unqualified hostname as the server).
Until 7.3, which fixed that problem, but introduced many more.
We do two things to avoid the problem.
1. When adding a client to the server, ensure you only have
fully qualified names in the "aliases" attribute of the client
(echo -e 'show name;aliases\nprint type: NSR client' | nsradmin -i -)
2. Ensure the client believes it is the fully qualified name. This
can be a little tricky. For Solaris and Linux the trick was to ensure
that in the /etc/hosts field, the fully qualified name was before the
short name on the line for its ip-address. There is a way in windows
to do it, but I leave that to my windows experts. If the client has got
this wrong, then you see that error about a misconfigured server. To me
it is a misconfigured client!

I have two clients with the same hostname on different subnets.
They are
'mirror.admin.csd.uwo.ca' and 'mirror.syslab.csd.uwo.ca'.
mirror.admin
has been around for a long time and works fine. When I added
mirror.syslab
I get this error on the next backup session:
mirror.admin.csd.uwo.ca:L:\ save: SYSTEM error: client `mirror' is
not
properly configured on the Sun StorEdge(TM) Enterprise Backup Server
Neither entry in nwadmin has 'mirror' as an alias. They are both
named
with their full name. mirror.admin is a Windows XP box while
mirror.syslab
is running Fedora Core 4.
Is this telling me I can't have two clients with the same hostname
even
when they're on different subnets?
Yes, and this is something Legato broke in the 7.x series. They,
however,
view the new behavior as an enhancement. This was discussed a
while back,
search the archives for more detail.
To get around it, use the "save -c full.client.name" in the "Backup
command" field for each of the clients that have short names that
conflict
with other short names.
