There was a bug as follows :
Issue
Cannot attach more than 6 disks to a Windows 2012 R2 VM.

Root Cause Analysis
While trying to obtain the SCSI id to attach a disk to, CS should ignore the reserved SCSI
id 7. But this is not being honored in case of VMs with SCSI controller of type 'VirtualLsiLogicSASController'.
And so in case of Windows 2012 R2 VMs, CS chooses to attach the 7th disk on the reserved SCSI
id and this fails on vCenter.

Steps to reproduce
1. Set global config vmware.root.disk.controller to 'osdefault'
2. Deploy a Windows 2012 R2 instance.
3. Attach 6 disks to the VM.
4. Try attaching a 7th disk to the VM - Fails.


Automated a Test case which try to attach 7 data disk to windows server R2 VM on vmware.
