We have an Equalogic SAN being replciated to our DR site via a MPLS connection. ON the SAN we have multiple virtual machines running. In case of DR, we want to bring up those machines at DR site, the problem is, that site is in a different subnet, when we bring up the Windows Servers, they have the prevous IP information defined in them...Anyone else ran into this? Looking for an automated solution as opposed to going to console and changing IPs/subnets/GWs...

Hello - Cisco addresses this with Data Center Interconnect solutions that provide the ability to extend VLANs and Subnets onto any number of other Data Centers without the burden of L2 bridging technology (aka STP). You may want to read the following Layer 2 Data Center Extension White Paper for more information.
