Powering off PowerFlex appliance two-layer cluster

This procedure applies to PowerFlex appliance two-layer cluster with VMware ESXi for compute nodes and the embedded operating system based on CentOS for storage-only nodes

1. Launch the PowerFlex GUI and log in to the primary PowerFlex MDM. Verify the PowerFlex cluster is healthy and no rebuild or rebalances are running by noting the Rebuild and the Rebalance widgets on the dashboard.
2. In the VMware vSphere Web Client that manages the PowerFlex appliance cluster compute-only nodes:
   1. Expand the clusters and shut down all application VMs running on the PowerFlex storage datastores.
   2. Disable DRS and HA on the customer compute cluster.
   3. Put the PowerFlex appliance compute nodes into Maintenance Mode.
3. Use iDRAC to do a Graceful Shutdown on the PowerFlex appliance compute nodes.
4. In PowerFlex GUI:

   Versions prior to PowerFlex 3.5

   Inactivate PowerFlex Protection Domains (both source and destination protection domains if asynchronous replication is enabled). In Configuration, select the Protected Domains and click More > Inactive. Click Inactivate in the pop up. Verify the operation is completed successfully and click Dismiss. Click OK and then type the administrator password when prompted. Repeat for each protection domain and verify that each is deactivated. Exit the PowerFlex GUI presentation server. Click Configuration > Protection Domain. For each protection domain click More > Inactive. Click OK and type the administrator password when prompted. Repeat for each protection domain and verify that each is deactivated. Exit the PowerFlex GUI.

   Click Backend > Storage and change the view to By SDSs. Right-click on a protection domain and select Inactivate. Click OK and type the administrator password when prompted. Repeat for each protection domain and verify that each is deactivated. Exit the PowerFlex GUI.

5. SSH to each of the PowerFlex appliance storage only nodes and shutdown the nodes by typing shutdown -h.
6. Use iDRAC to confirm the PowerFlex appliance storage nodes have been powered off.
7. In the VMware vSphere Web Client that manages the PowerFlex gateway VM:
   1. Shut down the PowerFlex gateway by running the command shutdown -h in the console.
   2. Confirm PowerFlex gateway VM is shut down by observing if vSphere shows the VM as Powered Off.
8. Using the appropriate VMware vSphere web client, shut down both CloudLink center VMs.
9. Using the appropriate VMware vSphere web client, shut down the PowerFlex Manager VM.
   NOTE:If you shut down the PowerFlex Manager VM while a job (such as a service deployment) is still in progress, the job will not complete successfully.
10. Power off the access switches first and then the management switch.
