TSM ba client version=6.2.1.0
Client OS version=Windows 2008 R2
Recently I faced this problem of tsm clients behind firewall miss their scheduled backups.I deleted CAD and configured tsm scheduler directly to poll tsm server.This resolved the problem.
Probable reason could be that when TSM server contacts tsm client behind firewall it fails to contact tsm client and hence don't get any reply.
I also noticed that client was not listening at default port 1501 while it was listening on server comm port 1500.
If any one struggling with this kind of issue they can try this workaround.
update the client option file (dsm.opt) to
ReplyDeletetcpclientport . the default is 1501. if there are multiple TSM CLIENT Schedular Services on the same machine using a schedmode of PROMPTED, it is important to ensure that each schedular service has a Unique tcp port to Listen for contact by the TSM SERVER .
