I am running Windows 2012 R2 VM on HP G8 DL360p Server. (ESXi 6.0U2)
I need to change SCSI Controller from LSI Logic SAS to Paravirtual.
Do I need to install drivers? If yes, what drivers and how?
When I click on ADD SCSI Device under VM settings, the SCSI Device is shown (unavailable) and greyed out.
1. Is there an article or a video with steps and instructions you can provide?
2. What are the reasons for performance improvements by switching to Paravirtual?
Thanks in advance and please advise.
First you have to add small disk to the same virtual machine from paravirtual adapter.Then it will automatically installed drivers to virtual machine. after that safely you can remove that disk & change your existing disk controllers.
Please follow below steps which is mentioned in vmware kb
To configure an existing Windows boot disk to use a PVSCSI adapter:
This procedure is required as the guest operating system does not have the PVSCSI driver and the guest will BSOD on boot if using the above method. This workaround forces the guest operating system to install the PVSCSI driver.

1 Are there any additional drivers installation on OS is required? Are controller drivers part of Vmware Tools?
2 Please explain the reasons to switch to Paravirtual controller?
Thanks in advance and please kindly advise...
you can refer below link.this include answers for your queries.
How do I go backwards if I need to go back to the original SAS controller from Paravirtual?
Are steps in reverse the same or is there something different needed to be taken into an account?
If you want to switch from VMware paravirtualized SCSI controller back to LSI you do not need to do anything. Just power off the VM and change the controller (since the driveres are aleredy installed in the system there is no need for any manual operation)
I tried, it works fine!
Thanks Kolla, kela wela tibbe. Den hari 😂
