Microsoft SQL Server 2012 Installation on VMware vSphere Virtual Machine Can Only Install to the “C:” Drive



There is a known issue when trying to perform a Microsoft SQL Server 2012 (Standard or Enterprise) Installation on a VMware vSphere Virtual Machine, running on VMware vSphere ESXi 5.x, Can Only Install to the “C:” Drive and the instance will be unable to “see” the non-C: drives.

The issue can occur on both Windows 2008 R2 and Windows Server 2012 based Virtual Machines.

The workaround is to disable the vSphere HotAdd/HotPlug capability for the Virtual Machine:

To disable HotPlug capability using the vSphere Client:

  1. Connect to the ESXi/ESX host or vCenter Server using the vSphere Client.
  2. Power off the virtual machine.
  3. Right-click the virtual machine and click Edit Settings.
  4. Click the Options tab.
  5. Click General > Configuration Parameters > Add Row.
  6. Insert a new row with the name devices.hotplug and a value of false.
  7. Power on the virtual machine.

For more information see the following VMware KB article:

Thanks to Natan Duer from Maccabi Healthcare Services for sharing the workaround!
