Hello,
I will try to answer a few questions:
Does LACP works on the NDMP backup with veritas?
yes (but it depends which will be the data path to the backup destination). check about topology at the end.
1. I have currently tapes drives configured with Hitachi NAS now, can we use the same tape drives to configure NDMP on netapp. Will there be any issues or errors with current tape drives which is working fine on HNAS?
If so how exactly the zoning should be done ( Tape Drives and Netapp ports zoning since i use LACP can i add both the ports on each node and make one zone per node). Is this the correct way ?
Are you using stand alone drives or is it a tape library with multiple drives? Normally, you would need a tape library that could be partitioned. You would assign partitions to NEtApp and HNAS (which would use different tape drives and slots on the tape library).
You tape environment uses FC? You said zoning, but also mentioned LACP. If FC, you need FC ports.
2. Is it mandatory to create intercluster LIF's?
No. You need intercluster LIFs for intercluster traffic.
3. LIF assigned should be in the same IP range as the backup network?
Please make it clearer
4. Any requirement that we should use Accelerator for NDMP from Netbackup ?
PS:-- For NetApp filers, Accelerator for NDMP supports only the DUMP format. Consult your NetApp documentation for specific details about its DUMP format.
Did you check Veritas Compatibility List?
It's important to understand the NDMP topology you want to use. Can you explain it better?
