I've tried to install the LSI Storage Authority (LSA) which, as I understand, is the replacement for Megaraid Storage Manager (MSM), and fully supported by LSI as the method for monitoring RAID controllers.

My hope was that I would be able to monitor the raid status for my ESXi 6.5 and 6.7 hosts using this software.
However, I encountered problems when trying to add more than a single ESXi host to the LSI Storage Authority server. Apparently there is a bug which prevents you from being to monitor more than a single ESXi server per LSA instance:

The workaround is to install an LSA Server per ESXi host, which just doesn't scale if you have more than a handful of hosts. And to be honest, I'd rather SSH to each ESXi host and run storcli to monitor the raid status, that have to install a few hundred LSA servers...
At this point I'm starting to lose hope. It is so frustrating that neither VMware or LSI/Broadcom appear to be taking ownership of this issue. It's almost as though they don't understand the gravity of the problem.
