We run a Windows Server 2008 on ESX 4.1 with the datastore on Cybernetics miSAN iSCSI disks.
We are installing a new database on a virtual terminal server. Right now it only has a 200GB C: drive. We have been requested to add a 160GB E: drive for the database.
If I go into the Windows Disk Management, I can shrink the volume, but only to 100GB.
I was able to extend the virtual disk size on the miSAN from 200GB to 300GB. I rescanned my storage adapters and ESX immediately saw the increase of the iSCSI disk to 300GB.
However, the VM still sees only 200GB to work with. If I go into the datastore's properties, I see the device capacity of 300GB but the primary partition is set to 200GB. There is an "Increase" button on this pop-up window, but it is greyed out, so I can not click it.
I do notice there is a Maximum File Size of 256GB, which I believe we set when we created the VM. What can I do to increase the disk on my virtual windows server machine?
