Hi Steve,
Tell the NetApp people to run following commands
You most look in the NDMP Debug log to find the key for your issue.

On the NetApp can you run 

>ndmpd debug 50

That will probably generate a message to you how you enable debug in 8.1RC2. I 
Think NetApp change how to enable Debug mode in OnTap 8.1.
If I don't remember wrong was the new commands

Options ndmpd.debug.enable on
Options ndmpd.debug.mode 50

But please see the OnTap command line information you get when you run ndmpd 
debug command.

After running a backup stg you will see more info in the ndmpd logfiles that 
you can find on \\vfiler\c$\etc\logs\???\ndmpd?????.log
And I can guess you will see a media error problem in their.

Best Regards
Christian Svensson

Ämne: TSM 6.3 NAS Filer backup stg issues

Hi All

I've got a problem with running backup stg of nas filer NDMP backups.

I have a TSM 6.3.1 server on RHEL 5.7 X86_64, an N-Series filer at Data On-Tap 
8.1RC2 and A shared TS3310 library with LTO5 drives. Actually I have two setups 
exactly the same in different cities, except one has more data and 3 drives and 
the other has less data and two drives.

NDMP backups are configured to write directly to tape and seem to work fine.  
The backup completes cleanly if slowly, and the limited restores I have done 
worked once I went to 6.3.1.

But, I want an offsite copy, and so run backup stg against the NAS primary tape 
pool.  This is consistently failing - but only on certain filer volumes. On the 
first filer with the problem it seems to copy correctly on volumes that are 
cifs shared, but fail on volumes that  are used by FC,  at least I thought that 
was the difference.  On the second filer there are no FC volumes, but somehow 
those copies are failing too.

TSM support points at the filer people because the error is a bad return code 
from an operation that is handed off to the filer.  I have been working with 
N-series hardware support on this for a month and only now realize that they 
have co concept of what the problem is..... they thought backup stg produced an 
NDMP backup.

Has any one else seen this problem?  Does anyone on the list know how to get 
traction on these sorts of issues from Nseries hardware support ?

Regards

Steve
