Networker DSA Configuration issues
Hi friends,
I've just migrated all my data to a NetApp FAS 2050 filer. This filer offers four CIFS resources to a Windows 2008 64 bits server resources named "\\nasIP\resourceX$" (with X from 1 to 4). This server is a Networker client, so first idea was setting up savesets like "\\nasIP\resourceX$\folderY" for this Networker client. Performance was so poor, getting 60 GB copied in tape in 4 hours.
Second idea was launching these savesets from Networker Server (Windows 2003 R2 x86 with Quantum tapes device fiber connected) as both servers are in same LAN network, getting 30 minutes shorter backup time for those 60 GB, so 3 hours and a half at the end.
Then I knew about NDMP, but I can't afford NDMP license in my Networker Server. And only then I reached DSA features that I guess free with my Networker 7.6 software and I think it's the proper way as my Quantum library is not direct connected to NetApp filer.
Since then I've been only testing my software in order to get a complete backup but I'm not suceeding yet. I'd like to write down here my client configuration so you can detect my mistakes.
From Networker Administration in Networker Management Console I named my client with LAN IP address, so
Client Properties:
General tab:
Name: 111.222.333.444
Savesets: I've tested...
resourceX$/folderY
resourceX$
folderY
with same failed result with message: 42925:nsrndmp_save: Too many arguments. Only one filesystem can be specified for backup.
Apps & Modules tab:
Remote user: user in NetApp, same user I use in order to established resource CIFS connection from servers. This is also Windows administrator user in both tested servers I mentioned before.
Password: user's password.
Backup command: nsrndmp_save -T -M dump
Application information:
HIST=Y
UPDATE=Y
DIRECT=Y
EXTRACT_ACL=Y
Globals (1 of 2) tab:
Aliases:
111.22.333.44
dnsname.domain
Globals (2 of 2) tab:
Remote Access:
host=server1 (Windows Networker client)
host=server2 (Windows Networker Server)
Storage nodes: nsrserverhost
I'd also like to point that I have no way to get filer setup details. This filer is external managed so I don't know if NDMP is active in NetApp filer but I guess the error messages could mention this issue. I'd like to get all this clear before having to ask for the parameter state.
So please I'd be very grateful if you could tell me where that configuration is wrong. Any help is welcomed.
Thanks for your attention.
Regards.
Angel.

The key issue seems to be the backup command itself. Instead of
nsrndmp_save -T -M dump
it should read
nsrndmp_save -M -T dump
This could already solve the problem.
Of course you must also not specifcy more than one entry in the save set list.

Further to what bingo has said, your backup set is wrong. Go to filer and see what qtree you are backing up and use qtree path as save set.
I would not put my hand in fire that DSA NDMP backup does not require NDMP license.

Thank you very much for your help. I changed the command and also the way I specified the saveset with /volX/folderY. I think these both worked although I got this new issue that I guess is something related to the remote user:
42597:nsrndmp_save: connect auth: connection has not been authorized
42610:nsrndmp_save: The NDMP connection is not successfully authorized on host
42884:nsrndmp_save: Not able to connect or authorize the client '111.222.333.444'
I have read that user 'root' is the only one that can be used to perform NDMP backups (I also guess DSA backups) and there is another issue to be resolved with root password that must be 8 characters maximum.
Could this be the solution (user 'root' as remote user and password less than 8 characters) as I'm using the user I was given to connect to CIFS resources? Is there any other valid user to perform these backups that could be setup?
Thanks in advance.
Regards.
Angel.

Hi Angel,
For an NDMP backup of a NetApp filer you will need a userid configured specifically for ndmp backups. From the filer the following commands will need to be run to generate a userid and password for the ndmp userid:
useradmin user add -g "Backup Operators"
ndmp password
for example:
useradmin user add ndmpuser -g "Backup Operators"
ndmp password ndmpuser
This will generate a random password for the ndmpuser which you would then specify in the Access field in the Networker client definition. This system generated password will be unique to each NetApp controller.

Hi Paul,
thanks for your answer. I could ask for that NDMP user and password, and what I'm getting now is just the following messages:
-----------------------------------------------------------------------------------------------------------------------------

-----------------------------------------------------------------------------------------------------------------------------
What does these messages mean? Do I need Networker NDMP license? What is Probe savefs that can be successfully backed up?
Thanks in advance.
Regards.
Angel.

Yes, you need NDMP license.

yes..u still need license...DSA just gives flexibility to backup to disk other than traditional SAN based tape only...licensing wise all the same....
