Using Expanded Metalun space with vSphere

Question

I am expanding a metalun on a CX4-480. the lun is part of a vSphere cluster. I am not sure of what steps to follow on teh ESX side.

Once i expand it on the SAN, i would think i should rescan the ESX host. Would i then go to the properties of that datastore and select "increase size" to add the new space to it. Then in turn, go to the properties of the actual VM and modify the properties of the harddisk and increase it there?

i guess whoever did the expansion decided to create new 200G vmdk file and then use dynamic disk on the host side to increase the size. That's one way to do it. Another way would be to resize existing vmdk file (2T max on Vsphere) and then use diskpart to extend the partition.

just a data drive for a File Server.

It is just confusing becuase this same LUn has been expanded before. it started out as a 1TB and then 200G was added. On the ESX side, the properties for the datastore show it as 1.2TB. but when i look at the VM settings, it has 3 hard disks assigned to it:

harddisk1 c:\

harddisk2 1TB

harddisk3 200G

When i login to the machine, it is all one drive made up of 2 dynamic drives of 1TB and 200G

Vsphere steps look right , on the VM side ..is it a data drive or OS drive ?
