解説:
Explanation
Upgrade
The upgrade process runs on a single node at a time:
Starts with the primary appliance
Non-primary node first
Control Path
Turns off all schedulers
Disable RestAPI for writes
Waits for ongoing management operations to complete
Backs up management DB
Disables Primary Appliance Failover
GUI and RestAPI are unavailable for a short period of time during Control Path failover
