Any reason why you still running 7.1 ?
I would personally NOT use BMR in an environment for which I have no support from Veritas.
The error that you are seeing is related to the NIC drivers in the SRT that you are using.
Could you please share all steps that you have followed to prepare for BMR restore?

Please have a read through all of the above - one or more should be relevant.
