Summary: Test to verify attaching 7th Disk to windows server
2012R2 instance
Key: CLOUDSTACK-9275
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9275
Project: CloudStack

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.
