Shutting down TSM on AIX
What is the preferred method of shutting down the TSM server on a AIX box when AIX is being rebooted? Is a kill command ok or is there a kinder way to shutdown TSM without using dsmadmc? David
Re: Shutting down TSM on AIX
Shutdown and reboot both send a kill -15 to processes. TSM listens to this kill signal and shuts itself down. If you have tape activity going, it is best to stop as much of it as you can, since some threads won't shut down completely until I/O is completed. bob On Thu, May 16, 2002 at 10:01:06AM -0400, David E Ehresman wrote: What is the preferred method of shutting down the TSM server on a AIX box when AIX is being rebooted?

Re: Shutting down TSM on AIX
Kill command is ok however keep in mind that you'll want to check what the TSM server is doing first before you do it. Make sure any backups/restores can be cancelled (and the appropriate people informed) as well as any other processes like migration and so forth. According to the TSM manual you should do: Disable sessions - prevents new clients from accessing TSM put permits existing sessions to continue Query sessions - check if any sessions are currently running Cancel session - cancel above sessions as appropriate Query process - check for any running processes Cancel process - cancel them as appropriate Then when the TSM server is quiet and you're ready to shut it down: Halt When you bring it back up use enable sessions to allow clients to access TSM again.. Are the above necessary? No not really.. doing a halt outright or sending a kill signal to the process is going to cause the TSM server to cancel everything anyways.. So if you know it's ok to do so then go for it. But I usually do a quick check and quiet the TSM server personally..

Also check for mounted tapes Q MOUNT. TSM will not dismount the tapes before it halts. Then when you start back up you have drives with tapes in them that TSM doesn't know about. On AIX with out 3494 library, I've changed the rc.adsmserv startup script to dismount any volume from each drive using the MTLIB command before TSM starts. This way I can be sure there are not tapes left mounted from TSM comming down before. I'm not sure how you would do it with other SCSI libraries..

Re: Shutting down TSM on AIX
So does anyone have a shutdown script that does all that they'd be willing to share?

Re: Shutting down TSM on AIX
For scsi I do the following before starting TSM: tapeutil -f /dev/rmtxx reset tapeutil -f /dev/rmtxx unmount /dev/null 21 This resets any scsi locks and unmounts any tapes. -- Phillip Ford Senior Software Specialist Corporate Computer Center Schering-Plough Corp.
