Hey all. New to TSM/large data backups in general.

I recently installed a few tape arrays, an AIX server with TSM, a couple of Dell 7610's with Fluid FS, and 4 Dell 6510 Equallogic disk storage arrays. We have about 200 TB of large data files to backup.

The problem I'm having is that datamover registration fails after TSM receives the backup type information. A packet capture and the logs confirm that TSM and NDMPD exchange authentication, which passes, server information, host information, and backup type information then TSM reports that registration fails.

Since the TSM disconnects immediately after receiving the backup type info I assume that the packet contains incomplete information. Below is the NDMPD logs which outlines the information passed to the TSM before the TSM closes the connection.

I'm increasing the verbosity of the TSM logs to get more information but I don't have it yet. I was hoping that someone could point me in the right direction as to what I need to change.
 
Have you set the right parameters when you defined the datamover - IP address (or DNS entry), TCPPort, correct user nme, etc?

Is the NAS device zoned or wired correctly?
 
Those parameters are correct, I have confirmed by packet capture and checking the logs on the Dell Fluid FS device.

The wiring is correct otherwise I wouldn't get the packet capture. As for zoning, I'm not 100% sure. My TSM consultant has done most of the configuration and flat file backups work (but are slow) this probably means that the zoning is correct.

If flat file backups are slow and the intent was LAN Free backups (datamover setup is NOT the same as LAN Free), then you don't have the right settings.
 
Unfortunately I don't really have the specifics as far as that goes. I'm relying heavily on my consultant for the configuration details. If you can be more specific as to what settings I should be looking for or what resources I can research to confirm the correct settings I would appreciate it. I'm flipping through online manuals but I'm not exactly sure what I'm even looking for at this point.
