Hello,

I have a customer who installed Netbackup 7.1.0.3, and have some troubles with NDMP.

Customer has EMC VNX , NAS , and support ndmp, he added ndmp host successfully, but when tried to create an ndmp policy, with the follwoing paramaters (policy type: NDMP, Client: ndmphost,), the following error is show when trying to add a new file to the backup selection list "Unable to detect selected host. error: ping(ndmphost). I have tried to add ndmp client with IP address instead of the hostname, but it didn't fix it.

did anyone got this issue?

thanks in advance.
