Re: Problem changing TSM server name

Hi,

For windows, you can remotely change the registry key
\HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\BackupClient\Nodes\
<node_name>\<ITSM server name> folder and after restarting the ITSM
service(s) things should work.

Regards,

Karel

Subject: Problem changing TSM server name

Greetings,
        I recently inherited a few TSM servers.  Their internal TSM
server name does match the DNS name.  The TSM clients connect to it via
the DNS name, but we would like to change the TSM server name to match.
For example, the DNS names of our standard are ABCD-TSM1, where ABCD is
a 4 letter abreviation of the site name.  But the internal TSM name of
these servers are ADSM, or TSM-SERVER1 or something.

        This is easy to change with SET SERVERNAME, but when I tried to
change one of them, I hit an unforeseen consequence.  The next night
when the client backups kicked off, all the clients failed to run their
schedules because of authentication errors.  The message in the activity
log showed the clients getting unknown client errors, and the client
name, instead of the real client name, looked like some sort of
encrypted garbage characters.
As soon as I set the TSM servername back to the original, they all went
back to working.

        This leads me to believe that the TSM servername is used during
the initial password exchange-and-save when the client first
authenticated and saved it's local password.  To fix this then, will we
have to go out to every TSM client one at a time and re-authenticate and
save the passwords?
Does anyone one know of a way to change the servername without touching
each of the clients?
