Adding space to ESXi 4.1 after adding a new drive to the RAID set

I am admittedly a novice when it comes to vmware, and this is a production system. Recently in order to add some more storage space I added a single additional drive to my RAID 5 set. I was able to get the Dell openmanage installed in ESXi and then expand the RAID to use the new drive.
Here is where the problem starts, I now need to add that space so that I can allocate it to one of the VMs on the server. I have been looking through the communities and found conflicting information about if and how it can be done.
If I go into the Volume properties using the vSphere client I can see the space listed for the device, but the partition only lists the old size. I took both VMs offline and hit increase, but there are no devices listed on the screen that opens.
I have attached a screenshot of the volume properties if it will help.
I have Windows backups of the servers, but no snapshots or anything like that. I can attach a USB drive to offload the images to if I need to.

Can someone please give me an easy to follow walkthrough on doing this? It seems that it is possible, but I also need to do this with the least downtime possible, as the server is accessed 16 to 20 hours a day normally.
