VMware 6 increase datastore size

Hi,
I have 2 datastores, main and secondary.  Each datastore resides on local storage but on separate RAID arrays/different controllers.  Main is filling up and I want to increase the size of it. How can I increase the size of the main datastore using the the space on the second array?  There is no data in the secondary datastore yet so I can do whatever I want with it.  I tried to just add a virtual disk and extend the volume in windows but it barks at me.  The volume requires contiguous disk extents

Thanks!

Thanks for the rapid response.
ESXi is installed on a USB drive.
Okay, if you have ESXi installed on USB flash drive, then you can proceed and expand with no issues, just be careful expanding across different LUNs.

It would be recommended to EXPAND the MAIN array.

Please explain further about the recommendation.  I'm not fully understanding what you mean.  Since I have 4 drives on 1 controller and 4 on the other controller, how could I just expand the main array?
Move the disks from controller B to controller A, and expand array on controller A.

subject to support on your controller for expansion, and hardware disks chassis.

Oh ok.  That's what I thought you meant.  I just scrolled up and saw your explanation in your first post.  I didn't see the additional information when you first posted.  It ended at "gui".  So yea, It's not supported on that chassis, so we had to do two controllers.  I'm thinking it'd just be best to keep leave the additional virtual disk on that secondary datastore and just move some shares off the first disk onto the second.  If I lose the LUN, it'll just be that drive.  Agree?

I would agree.
