ndmp error.

Hi
Please help me :(
I installed the nb6.5. I would like backup my NetApp filer via ndmp via network.
I configured in the nb the ndmp hosts and i create the policy.
The master server see the library and the master server can backup to the library.
I try to start the ndmpo policy which backup the filer , but the policy failed with this error message.
I don't know what is the problem because the nb 6.5 i think support the remote ndmp backup via network.

  • Ouch that looks like a hairy one.
     
    If I were you, I'd be looking more at my NDMP host and not so much the Netbackup host.
     
    If you have the right path, the right syntax, the right setup (double, triple check these, that can never hurt) then I would then be looking at my NDMP Host and or the comms to that box, although this doesn't look like a comms issue.
  • You may have done this already, but it is worth testing the NDMP authentication from the master/media server to the netapp box is correctly working
     
    Run "tpautoconf -verify ndmp_host_name" and verify that access is granted using an account that has appropriate access to the NAS (we use "root"), is using the correct version of NDMP (ie. matched on the filer; 4 I think is the latest supported by Netapp) and that the correct style of NDMP type backup is enabled for how you are configuring it ie. 3-way, local or remote.
     
    You should see something similar to this (from master server cmd line AND the media server doing the leg work, if they are separate):

    Host has SnapVault Secondary license installed
     
    Are you trying to backup native volumes (CIFS/NFS) or snapshots? I have been advised in the past by Netapp support to use a trailing "/" at the end of the pathname too - although ours works with or without, I must admit. Try a path of "/vol/volname/"?

  • hi,

    did you ever resolve this issue? I seem to have the same problem.

  • Hi,
    Is there any other solution other than reconfiguring the NDMP backups? We are facing the same issue.

    Path of the data is correct. We have been running NDMP backup since an year and this error has started since 3 days.
    Ran tpautoconf command and got the below output.

    Connecting to host "san1" as user "svcSanBackup"...
    Waiting for connect notification message...
