Backup db chalenges with 7.1.8
January 25, 2018 05:59AM
Hi guys,
I'm facing a new challenge because of the security enhancement in 7.1.8. In the past I installed 7.1.7 servers on a cluster configuration, which was working without any issues. With 7.1.8 TSM starts checking the GUID of the $$_TSMDBMGR_$$ node used and this changes as soon as the server switches to the other cluster node. This causes the backup to fail:

ANR0406I Session 49 started for node $$_TSMDBMGR_$$ (DB2/Linux) (SSL 10.70.11.118(58814)).
ANR2987W Session ended because of machine GUID or local host IP address mismatch.
ANR3259W Session 49 for node $$_TSMDBMGR_$$ (DB2/Linux) refused - $$_TSMDBMGR_$$ node from an untrusted system is not allowed.
ANR0403I Session 49 ended for node $$_TSMDBMGR_$$ (DB2/Linux).

I found the circumvention to specify the parameter DBMTRUSTEDGUIDIGNORE YES in the dsmserv.opt, but that looks more like a fix than a solution...
How should one solve this issue properly?
Thanks for any help in advance!
Kind regards,

Hi guys,
For the record: the issue below was caused by a misconfigured API client. On one cluster node it was using the hosts IP address as tcpcerveraddress, on the other one it used tcpserveraddress localhost. After setting them both to localhost the database backup was working again on both nodes.
