Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Power off the PowerFlex management node

Power off the PowerFlex management node on the PowerFlex management controller VMware ESXi host. This procedure is only applicable if a PowerFlex management node (single non-HA node) is in use.

1. Log in to the PowerFlex management platform primary node using SSH and run the following commands to halt the CMO database:
   # echo alias k="kubectl -n $(kubectl get pods -A | grep -m 1 -E 'platform|pgo|helmrepo' | cut -d' ' -f1)"
   # kubectl config set-context default --namespace=$(kubectl get pods -A | grep -m 1 -E 'platform|pgo|helmrepo|docker' | cut -d' ' -f1)
   # echo $(kubectl get pods -l="postgres-operator.crunchydata.com/control-plane=pgo" --no-headers -o name && kubectl get pods -l="postgres-operator.crunchydata.com/instance" --no-headers -o name) | xargs kubectl get -o wide
   # kubectl -n powerflex patch $(kubectl -n powerflex get postgrescluster -o name) --type merge --patch '{"spec":{"shutdown":true}}'
2. Verify the DB shutdown. Only the PostgreSQL operator pod pgo must remain the same when running the command:
   #echo $(kubectl get pods -l="postgres-operator.crunchydata.com/control-plane=pgo" --no-headers -o name && kubectl get pods -l="postgres-operator.crunchydata.com/instance" --no-headers -o name) | xargs kubectl get -o wide
3. Gracefully shut down all the VMs and vCenter VM:
   1. Log in to VMware vSphere Client.
   2. From vSphere Client > Shortcuts > Hosts and Clusters.
   3. Browse and right-click the VM and select Power > Shut Down Guest OS.
4. Shut down the vCenter server VM gracefully:
   1. Log in to the VMware ESXi using the host client.
   2. Click Virtual Machines > Select the vCenter VM and click to open a browser console.
   3. Press F12 to shut down the VM.
   4. Enter the root password and press OK.
5. Shut down the VMware ESXi server gracefully:
