Hi Andrew,<br />
<br />
Sorry for the late follow, up. It turned out to be a moot point in the end, the client had a Microsoft 'Store Simple' Device, that had 6x5TB volumes presented to the ESX hosts, which then presented them to the guest as RDMs. I ended up removing the volumes from the hosts, and connecting the VM directly to the storage via iSCSI/MPIO, since then the problem they were getting (VM freezing with Event ID 129 and needing to be rebooted) has ceased.

I have a VM that has various RDM disks presented to its LSI SAS SCSI Controller. I need to change the controller to Paravirtual. <br />
<br />
I had a read of <a href="https://www.vladan.fr/safely-change-lsi-logic-sas-vmware-paravirtual/" rel="ugc">this</a> but it appears to be geared toward boot disks<br />
<br />
Anyone have some advice?

Change LSI SAS to Paravirtual iSCSI Controller

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
