Netbackup smart enough to use multipath fibre?

[msleeper]

I'm new to fibre channel and multipathing so if something below sounds nubish please forgive.

My question is: Is Netbackup Enterprise-6mp4 smart enough to NOT send all the data to the drives down just one fibre? I don't mean two lines to one drive, I mean will a multipathed server send data to two drives down different fibre connections.

For details read on:

I have six LTO-2 drives that are each connected via fibre to a switch. My media server has TWO fibre connections going to the same switch, it sees all six drives twice because of this. Since my media server sees each drive as two devices I was allowed to configure each drive using two device paths. For example drive 0 is seen by my media server as /dev/nst0 and /dev/nst6. If all the data for all six drives is only going down one fibre I'm going to have some serious bandwidth problems. I have no problem manually defining each drive to only be seen as /dev/nst0 or /dev/nst6 , etc., this should force data down each fibre. However I'd like it if Netbackup would do this for me.

Thanks,
Mark

Just because the VERITAS documentation states something as certain, that does not make it a fact and that is truth.
