Hi

Netabackup master and media server 6.5.3 release on Linux Red HAt AS 4 

filer1 : NetApp Release 7.3.2

filer2 : data ontap 8 


I'm trying to make a backup from netapp filer1 to filer2 that owns tape drive , by netbackup master server .

I correctly zoned on the SAN tape drive, filer2 and filer1 FC ports but when i run the backup policy i get, on the filer2 logs:

Hi All

I think the problem is related to Firewall ACLs  between Data server and Tape server , so, following  an enterprise policy, we must prevent traffic btween them...in the mean time we've found another solution using Shared Drive Options between the two NDMP hosts.

Thanks to everybody , anyway.

What type of tape library/drive/robot do you have?  Can multiple hosts control the robot?  Who has control of the robot?

Hi Matt

We've a StorageTek tape library controlled by ACSLS robot and a pool of StorageTek T9940B tape drives ... not sure about multiple hosts robot control capability , should say no ... 

Our goal is to use the tape drive attached to filer2 to make an NDMP backup driven by filer1
I suspect some incompatibility between different releases of Data Ontap on the two filers.... have to go deep with this

Thanks
