Dell PowerFlex Appliance with PowerFlex 3.x Administration Guide

Powering off a PowerFlex appliance hyperconverged cluster

To safely power off the PowerFlex appliance cluster, power off one component at a time in the order specified in this procedure. This procedure applies to PowerFlex appliance nodes with VMware ESXi.

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 observing the Rebuild and Rebalance widgets on the dashboard.

2. Log in to the VMware vSphere Client of the vCenter that manages the PowerFlex appliance cluster.
   1. Expand the clusters.
   2. Shut down all customer/application VMs (not SVMs) running on the PowerFlex storage datastores.
   3. Disable DRS and HA on the PowerFlex appliance cluster and put the nodes into Maintenance Mode.
   4. Once the node is in maintenance mode, power off the vCLS VM.
   CAUTION:Do not shut down the SVMs as this can cause data loss.
3. In PowerFlex GUI:

   PowerFlex

   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 type the administrator password when prompted. Repeat for each protection domain and verify that each is deactivated. Exit the PowerFlex GUI presentation server.

   Click Backend > Storage and change the view to By SDSs. Right-click a protection domain, and select Inactivate. 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.

4. Shut down all the SVMs.
5. From the VMware vSphere Client of the vCenter that manages the PowerFlex gateway VM and CloudLink center VM:
   1. Shut down the PowerFlex gateway VM.
   2. Shut down both CloudLink Center presentation server VMs.
6. Use iDRAC to do a Graceful Shutdown on the PowerFlex appliance nodes.
7. Using the appropriate VMware vSphere Client:
   1. 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.
8. If required, power off the access switches first and then the management switch.
