On an NVSwitch system with a driver release before 620, what must match the driver version?
Why D is the answer
Fabric Manager
Before release 620, the Fabric Manager package must match the driver package, and a mismatch can stop the service.
In detail
- A version mismatch can stop the service.
- From driver release 620, Fabric Manager is versioned standalone.
Use case
An illustrative scenario, not a real incident.
On a driver release before 620, an update leaves Fabric Manager behind, and the service will not start.
