Hello Nicholls,
The first question I have is around the upgrade. If i put the latest code on will there be any disruption at all?
- Upgrade old switch MDS9222i is a ISSU non-disruptive process
- you wiil also need to upgrade Fabric Manager to 5.0.1 the same Release number as the switch or higher. In this case, 5.0.1 or higher. Preferred higher FM release
The second question is how can i make the new switch the principal switch with minimal downtime?
- Assuming the configured domain ID left as default "preferred" on all switches
- you can change switch priority to 1 or 2 to assume principle and restart fcdomain non-disruptive.
ex:
On the switch to be principle
conf t
fcdomain priority 2 vsan xx
fcdomain restart vsan xx
