Protection jobs "sometimes" fail with NDMP errors

Hi,

I have a hourly schedule in SMO at hh:30 and an hourly schedule in PM at the hour to protect the smo backup. Sometimes, the protection job fails with a ndmp error but it usualy works.

After the step of setting the snapshot name at source (ex: Set source snap to 'smo_smoasm_f_h_xxxxxxxxxxxxxxxxxx), the next step fails with

Source: netapp2:/SMO_DATA/-

Destination: netapp12:/SMO_DATA/dfpm_qtree_73_1938_1945

Bytes Transferred: Unkwown

Error Message:netapp12.de.lan:Couldn't authenticate NDMP connection to host 10.68.123.161

10.68.123.161 is the IP address of netapp12

and ndmp credentials are set correctly in Ops Mgr (both netapp2 and netapp12 are seen OK for System status, Login Credentials, NDMP status and NDMP credentials in the Management Console).

Re: Protection jobs "sometimes" fail with NDMP errors

Hi,

Which is the version of Protection Manager you have ?

You could take a look at this burt to see if it matches your issue and also whether you have the version that has the fix for it.
