Just looking at the official course agenda and it lists:
"12 • Perform vSAN cluster scale-out and scale-up operations"
"14 vSAN Troubleshooting"
I would assume that would involve:
1) Adding a storage disk to a Disk Group to each node (or adding another node to the vSAN)
2) Simulating a Cache or Storage disk failure in a node (causing the volume to become degraded) by pulling a disk from the chassis
The real-world remote-hands datacenter maintenance technician would happily charge EUR 1000/drive in labor to perform these task >:}
(Just...the most basic operations. Very difficult to do those disk-related operations if the hardware is tucked away.)
Anyway, thank you all .
