Hi Alan.
Chap 7 of the Admin Guide is the best doc I've found. 

First off, are you going to send the data via TCP/IP and have it land in
a regular storage pool, or attach a tape drive directly to your Celerra
via your SAN?  You will find in Chap 7 that those are two very different
scenarios.

If the latter, then yes, you have to log into the Celerra and find out
what IT thinks its device name is, after you get the tape drive
attached.  

If you are doing NDMP dumps across the SAN, all the TSM server is doing
is sending a "Go forth and run NDMP" command to the Celerra.  The
Celerra is doing everything else, so it has to know how to find the
drive.  

If the doc doesn't help you, feel free to contact me directly, I'll try
to dredge up my notes.

Hi, folks.

I'm in the happy state of needing to attempt some NDMP backups.
Remember that 12TB FS conversation we had a while back?  Well boy
howdy, someone has just presented me with one.  We're failing to
complete backups in any reasonable timeframe.

I intend to continue experimenting with The Right Way, but I need a
stopgap, and it looks like NDMP is it.


But I'm having difficulty deciphering some of the instructions: they
talk about telling the DataMover the controller, ID, and lun.  I may
be dense, but I'm accustomed to using rmt devices or WWNs.

Anybody got a pointer to the Fine Manual ?  The logs of this list
include a tantalizing reference to success after "reading between the
lines a little bit"; but I was unable to find anything concrete.


I'm on  Version 5, Release 5, Level 3.0 of TSM, in case it matters.
