How to trigger failover for Azure Cache for Redis using CLI

Maulin Shah (Crest Data Systems Private Lim) 40 Microsoft Vendor

I have setup the two Azure Cache for Redis, one in the primary region and another in paired region. After that I have setup the Geo replication between this two servers using replication link. so now I want to trigger a manual failover on this so how we can do that using the az cli or REST API? Using portal it's a straight forward way but I didn't found anything in the doc related to az cli or REST API

Maulin Shah (Crest Data Systems Private Lim) Azure Cache for Redis provides several ways to trigger a manual failover between paired regions, even if the portal isn’t your preferred method. You need to execute the server-link create command with the cache names reversed like this: az redis server-link create --name cache2 --resource-group testResourceGroup --server-to-link cache1 --replication-role Secondary

cache2 is old secondary or new primary
cache1 is old primary or new secondary Regards, Oury

Can you please check the docs which you have shared? that doesn't provide any information related to trigger Manual failover, it's just showing how we can do the force reboot

Yes by using this you can reboot the primary node and by default it will move to secondary and this is how you can do check failover using Az cli

Hey, I have tried this but it's not working as expected.
When I am doing force-reboot it trigger the reboot in next 2 minutes but when I am checking server-link details, it's not updating the primary server as expected. so is there any explicit step that we need to do?
