The new product name is ONTAP Tools for VMware vSphere (at this moment, version 9.8P1, which may or may not have Log4j fixes - you'll have to check). It's the same product as Virtual Storage Console for VMware vSphere, but with some bug fixes and a better name. Unfortunately, NetApp didn't sufficiently advertise this change and I kept running the old 9.7 version until I lost five VMs on one of my vVols, likely due to those bugs which have since been addressed. I have since removed ONTAP Tools for VMware vSphere from my environment because VAAI now provides the Native Snapshots I wanted and I no longer needed vVols. I also wanted to reduce complexity.
The upgrade from 9.7 to 9.8 was uneventful for me and the new version worked well while I ran it. If you want to upgrade to 9.8P1, maybe make sure that 9.8P1 is not "older" (by date) than the version you're upgrading from.
As far as the snapcenter plug-in. After completing the workaround that vmware provided for the vcenter 7, my snapcenter would no longer deploy. I implemented the workaround for the snapcenter and the plug in still wont deploy on the snapcenter. Any ideas or suggestions?
