Power off compute resources for a NetApp HCI system
To power off NetApp HCI compute resources, you need to power off individual VMware ESXi hosts as well as the VMware vCenter Server Appliance in a certain order.
-
Log in to the vCenter instance controlling the NetApp HCI system and determine the ESXi machine hosting the vCenter Server Virtual Appliance (vCSA).
-
After you have determined the ESXi host running the vCSA, power down all other virtual machines other than the vCSA as follows:
-
Select a virtual machine.
-
Right-click and select Power > Shut Down Guest OS.
-
-
Power off all ESXi hosts that are not the ESXi host running the vCSA.
-
Power off the vCSA.
This will cause the vCenter session to end because the vCSA disconnects during the power-off process. All virtual machines should now be shut down with only one ESXi host powered on.
-
Log in to the running ESXi host.
-
Verify that all virtual machines on the host are powered off.
-
Shut down the ESXi host.
This disconnects any iSCSI sessions open to the NetApp HCI storage cluster.
