Hardware Certification - SCSI Controller Type Question

[sfields]

Arethe VM SCSI Controller types defined in the Storage Certification Guide mandatory ?

I've installed Windows 2008 Server on a VM with the Controller type LSI Logic SAS (as far as I see, I cannot change this before an installation) and after the installation was completed and VM booted ok I powered off and changed the controller type to VMware Paravirtual. VM couldn't boot. I changed the controller type to LSI Logic Parallel and got the same result - VM couldn't boot Windows.

Can I use LSI Logic SAS on all VMs where I cannot change the controller type or it won't pass Verification test ?

Thank you in advance.

It's even more serious: after VM could not boot with these SCSI Controllers, I changed it back to LSI Logic SAS and it couldn't boot with it.

[Linjo · Accepted solution]

The reason it can not boot is that there is no driver installed for it.

To go around that, add another controller of the new type, boot windows and let it install the driver for it, then shutdown switch the first one around and you should be fine.

Thank you, Linjo, but I don't know how to add a SCSI Controller. From vSphere client GUI I can only change the type.

Any hints ?

But unfortunately this trick doesn't work for Linux (RedHat or SuSE) VMs.

When I am installing the OS on VM from the workbench - ho do I define the SCSI controller type ?

I'm having the same issue with the Linux VMs. Two of the RHEL vms installed via installation helper were deployed with LSI Logic Parallel (as there is no option to change it within workbench), but need to be changed to LSI Logic SAS. I was able to add an additional controller and mkinitrd, but the GOS fails to boot afterward.  Anyone have guidance?
