NDMP filer to server worked once

[fuzzballer]

System: Windows 2003R2 SP2, TSM 5.5.4.2, diskpool 1.8TB and NetApp filer. No firewall(windows or otherwise, no gateway issue. All devices are internal and are only going through a switch.
Defined node type=nas, defined datamover with userid and password. Tested backup to diskpool without issue. Worked as expected.
Changed from fibre to iSCSI for diskpool and started having issues and could not get the backup to work. Moved back to fibre because the speed of the iSCSi was too slow for all of the backups to complete but we still cannot get the backup node to work. In the logs on the NetApp we can see the connection being made and authentication being approved and then immediately see the connection closed with the following entries in the act log:

Opend a PMR with IBM but got first level support and they are going over all the steps we have covered so I have come to the best forum I know for some assistance. I tried to answer some of the basic questions at the start. Any assistance is appreciated.

We resolved the issue. Once we ran a trace and looked at the file we noticed an unusual IP that the datamover was attempting to attach to and discovered that the old iSCSI NICs were still enabled. Once we disabled those NDMP worked like a champ. Only bad part is it still has to go to tape since the diskpool is not large enough to hold the entire backup. Oh well.

Hello,

I am getting the same error now.We are backing up NetApp NAS using NDMP with a dedicated 1Gig interface.I am getting the same error which you mentioned.I looked into the host file of the TSM Server and everything looks fine but what steps did you take to resolve the issue?

You said you have disabled old NIC's...Is it on the TSM Server and how did you find that old NIC's were the problem?

Here is our environment
We have a backup VLAN for backups on TSM Server and even the filer is connected to the same Network switch and is configured on the backup VLAN with a dedicated 1Gig interface.The problem here is when it is trying to communicate with the TSM server through backup VLAN we are having issues...Is this something related to Network?Any suggestions are highly appreciated.
