I'm trying to build storage(LUN) based replication DR site for SAP ECC with MSSQL 2008R2. Please let me know how to taken care of below -
1. "SAP License" as it is based on hostname? Need to keep DC & DR servers with same host name??
2. How to manage automatic switch over in case of primary site failure??
3. Can we do reverse replication if primary DC is down & comes up after day or two??
Your question seems to be realted to storage not SQL server you should post your question in forum dealing with storage. You should also involve SAP vendor regarding your license question.
Please mark this reply as answer if it solved your issue or vote as helpful if it helped so that other forum members can benefit from it.

Is that we are looking for something at Sql Server 2008 R2 customized ways too?
Certainly if you look at Disk and SAP license part then you need to check with them.
