How to Shutdown Cohesity cluster
Steps to shutdown cluster
Verify the cluster’s health and confirm a healthy state to shut down the cluster.
Note: Shutting down a cluster is a disruptive operation and stops all IO.
- Verify the current status and health of the cluster.
- On the cluster, CLI or GUI, verify the current health and physical condition of the cluster.
- Shut the services down gracefully using the below command.
iris_cli cluster stop
- Shut the nodes down individually, either use IPMI to power off the nodes or run shutdown.sh on each node after logging on to the node using ssh command.
ssh <node IP> shutdown.sh
- Perform any maintenance or physical changes after shut down operation.
After the maintenance activity, bring the cluster online by powering on the nodes.
- Make any Network or re-ip adjustments if needed.
- Once all the nodes are powered on and can communicate on the network, execute the following command on any node to start the cluster.
iris_cli cluster start
- Wait for 15 minutes and verify all the current health conditions.
