Amer,
I don't know if your question has been answered yet. I have posted a link to a licensing document associated with your customers equipment.This guide should point you in the right direction to solve your problem. You can get licensing in several ways: feature, module or bundle/chassis based licensing. You may need all 3 of the licenses. Advanced Services Package N7K-ADV1K9 Storage Enterprise PackageN7K-SAN1K9 are both feature-based licenses and the N7K-F348XP is a module-based license. Licenses are independent of each other. I would suggest that you identify what licensing your customer has currently and then you will be able to identify whether you need to purchase additional licensing or if your customer already has the right licenses then you would just have to enable/"turn on" the license. Please let me know if I have answered your question or if you have additional questions.
Regards,
Brad
