For disk maintenance, I need to shut down both nodes of a SQL 2014 active/active cluster (DB + AS services). Not only maintenance mode for FCI but both VMs shutdown (infrastructure requirement).
- Shutdown applications
2. Failover one node to the other (ends up with 2 instances on second node). Then can shutdown VM1(node that does not contain any cluster resource)
3. On remaining VM shutdown cluster service (from the Cluster Manager) or PS Stop-Cluster
4. Shutdown VM2
5. restart first node (both instances restart on this node)
6. Restart second node.
7. Failover instance to second node
My question is if I stop-cluster before VM shutdown do I have to start-cluster once the VMs rebooted or the cluster will automatically start? I do not have environment to test.
the cluster resources contain only SQL + AS + drives into the resources as per below.
Thank you,
