How to Configure an Additional HBA on a Cisco MDS FC Switch (vMware v5.0)

In my current environment I have 3 sites, two host per datacenter in a single cluster. My objective is to install an additional host on site A and Site B to allocate more resources to each datacenter.  Each host will be configured with 2 HBAs per host. Once the objective is reached, I will have three host per site with two HBAs per host.  

Environment: EMC VNX5300, MDS FC, NAS Block Storage, RecoverPoint, Replication from site A to Site B.

1. How should I configure the 2 existing Cisco MDS FC switches to support the new host?
2. How do I load the HBA driver on an ESXi v5.0 server?
3. What risks exist on the array when this type of upgrade is performed?

Thank you for your support.

My background is in managing Brocade fabrics in a similar environment.  MDS fabrics behave slightly different during zone creation as it relates to FCIDs and manually configured PWWNs.   Also, thanks for the tip on the Emulex adapters. I am almost certain vMware require a driver to be loaded for the adapter.  I will plug it in first and see what the outcome is. Thank you for the link it was helpful.

I am looking for more real world experience relating to the MDS 9000 series. What pitfalls to look out for and best practices when configured in a redundant configuration.

Any known problems for the MDS if I connect the fiber but postpone activating the zone for awhile?  With the older model Brocades this was problematic.

Thanks
