NDMP 3way heterogenous no tape to disk only ?

[schellh]

Hello,

just a short Q. NAS_NDMP_interopMatrix.pdf tells 3way heterogenous ndmp is possible. But in tsm docs i always find tape would be needed ?
I was asked to plan a TSM NDMP Backup w/o library for an emc nx4 so:

is it possible without tapes ? only to some disk based pool ?

thanks

I'm trying to figure this out as well. I don't have an answer, I'm sorry, I'm just seconding this question.

We have three TSM servers, and our site has just bought a Celerra/Centera system to replace our current storage infrastructure. I'm tasked with implementing NDMP backups of these, first time I'll have dealt with NDMP at all. I would like to set it up to use TSM's existing disk pool for backup, but all the documentation I can find assumes that I will be setting up NDMP to run to tape. Has anyone set up NDMP to back up to disk?

Hi,

I would like to use disk as well, but I got the following error message:
ANR4794E The NAS file server x.x.x.x failed to open an NDMP data connection to the TSM tape server. Please verify that the file server is capable of outbound data connections.
I have tried to make a NASDISK pool as suggest and I have tried to make a NAS TAPEPOOL (filedev sequenciel). but with negativ result.
Harry can you confirm that you have a setup running as you have descript.

Hi,

yes, I have checked if it works before posting it.
Here is the output (tested it just now again)

I encountered the very error you see - the key was to disable the Windows firewall - there was one confusing thing - Windows Firewall service was not running (when I tried it first) and I got your error. I had to start it and turned the policy to "Firewall off" - it works since then. I do not dare to guess what was the cause ...

Hi Harry,

Thank you...

You are right, this is a firewall issue...
Have to control the trafic, therefore I had to make this statment in the dsmserv.opt:
ndmpportrange 2020,2020 (If I just want to use a single port) the portnr can be from 1024 - 32767
