NDMP changes in 5.6 ?
I just upgraded my NS80 to 5.6.40-3 ..and my 3-way NDMP backups are not running anymore. I know TSM 3-way NDMP is not officially supported by EMC but it has been working for a long time now. The only change that has been introduced is DART upgrade (going from 5.5.30 to 5.6.40). TSM complains that i can not communicate with datamover. From 5.6 documentation i see that port 10000 remained the same, i was able to telnet to port 10000 from TSM server to datamover interface. I even reset ndmp account password on datamover, but any change that i do in TSM that requires communication with datamover fails. Any idea ?
Thanks
Thanks

Server Version 5, Release 4, Level 1.2, Command Line Administrative Interface - Version 5, Release 5, Level 0.1 and for another backup-site Server Version 5, Release 5, Level 1.1.
I use NDMP over IP to a storage pool, not direct to tape.
The only thing I noticed was I had to add a static route to direct NDMP-traffic over the correct interface on the mover. Fastpath didn't work as expected.
Setting NDMP and PAX debug - do you see any traffic from the server trying to establish a session on the mover?

actually according to the support matrix heterogeneous 3-way NDMP is supported with both IBM TSM 5.4 and 5.5 for DART 5.5 and 5.6 with the only restriction that VBB isnt supported.
heterogeneous meaning that the data destination (tape) is not a Celerra but the TSM server
for normal 3-way with another data mover as the destination the support matrix says not supported (strangely)

Didnt we have that some time ago here on the forum and issue turned out to be a dual-homed TSM server ?

i am running TSM 5.4.2 ....i had this running for almost a year now ..but as soon as i upgraded over the weekend, it's not working anymore. When on the server i issue "backup node SERVER_2 /filesystemname mode=full toc=yes" , the command returns immediately with
"ANR1763E BACKUP NODE: Command failed - see previous error messages or view the activity log.
ANS8001I Return code 4".
If i look in activity log there is nothing there. If i try to modify datamover properties in TSM, like changing username that it uses for ndmp it gives me this error
ANR1776I Data mover SERVER_2 has been updated, however a
connection to the data mover failed. Please check the
attributes of the file server specified in the update
command. (SESSION: 6198)

this is my original thread with dual-home TSM issue:

In this case the only thing that changed was code on datamovers. Unfortunately i did not document static routes on my datamover before the upgrade, but from i can see they are still there. When i set static routes on datamover they are permanent right ? I guess i am back to the drawing board running tcp/ip traces and see what's going on

yes, things change
looking through old support matrixes it looks like qualification for heterogeneous 3-way NDMP for TSM 5.4 first appeared in the May 2008 support matrix
Are you using "normal" or heterogenrous 3-way ?
