(Note: SESSIONINIT does not support the CAD)
The problem was how to update 75+ Windows servers options file and then restart the TSM Scheduler. So you can change any MANAGEDSERVICES options to WEBCLIENT using a client option set, but SESSIONINIT is another problem. As it turns out, if you set SESSIONINIT on the TSM server you have to put the HLAddress and LLAddress in the node definition on the server. The client dsm.opt must have the TCPCLIENTADDRESS and TCPCLIENTPORT in the dsm.opt. What we didn't know was that we also had to put SESSIONINIT SERVERONLY in the dsm.opt also. If you set SESSIONINIT on the TSM server and not on the client and the scheduler was defined with /validate:yes then you will get "password" errors and the scheduler will crash. The reason for this is that TSM does not allow client initiated sessions, but the scheduler when started is trying to validate its password. Since the scheduler can't validate the password it fails similar to when the password has not been set when using PASSWORDACCESS GENERATE.
We had the TCP Client settings, but adding SESSIONINIT to all 75+ servers would have been a chore...unless you know how to use the Windows command prompt and dsmcutil. Here's how I added the SESSIONINIT option to all 75 servers.
Example of how to remotely add a line to the dsm.opt
c:\echo SESSIONINIT SERVERONLY >> \\WINSERVPRD20\C$\progra~1\tivoli\tsm\baclient\dsm.opt
I put the command for all 75 into a batch file and ran it looking for errors (not all our servers had TSM installed in the default location). Then I used the dsmcutil command to stop and start the TSM scheduler remotely.
Example of stopping and starting the TSM Scheduler service
c:\C:\progra~1\tivoli\tsm\baclient\dsmcutil stop /name:"TSM Client Acceptor" /machine:WINSERVPRD20
c:\C:\progra~1\tivoli\tsm\baclient\dsmcutil start /name:"TSM Client Acceptor" /machine:WINSERVPRD20
I needed to restart the scheduler on all 75 servers so once again I created a Windows command line batch file with the following commands in a list and it restarted all 75 quickly and easily from my own desktop.
