Power off a PowerFlex appliance

To safely power off the PowerFlex appliance, power off one component at a time, in the order specified in this procedure.

About this task

Power on workflow:

  • Check PowerFlex health, and rebuild status
  • Power off all production cluster VMs on VMware vCenter (except the management virtual machine for controller cluster, SVM on both controller and production cluster, and VMware vCenter VM)
  • For PowerFlex file:
    • For PowerFlex file enabled system with storage-only:
      • Power off the PowerFlex compute-only nodes with VMware ESXi
      • Power off PowerFlex file nodes
      • Deactivate PowerFlex protection domains
      • Power off PowerFlex storage-only nodes
    • For PowerFlex file enabled system with hyperconverged:
      • Deactivate PowerFlex protection domains
      • Power off PowerFlex hyperconverged nodes
      • Power off PowerFlex file nodes
  • For all other PowerFlex systems:
    • Power off the CloudLink Center VMs that are running on management vCenter
    • Deactivate PowerFlex protection domains and power off PowerFlex storage-only nodes (both source and destination protection domains if asynchronous replication is enabled)
    • Power off PowerFlex compute-only nodes with VMware ESXi
    • Power off VMware NSX Edge nodes
    • Power off PowerFlex storage-only nodes
    • Power off PowerFlex hyperconverged nodes with VMware ESXi
    • Power off the PowerFlex management controller 2.0
      CAUTION:The power off procedure for PowerFlex management controller 2.0 and the PowerFlex production cluster are different. To power off PowerFlex management controller 2.0, see Power off the PowerFlex management controller 2.0.
    • Power off PDUs
NOTE:Powering off must be completed in this order for the components that you have in your environment.

Identify node types in the PowerFlex Manager:

  • For PowerFlex hyperconverged nodes, click Block > Host or Block > SDSs.
  • For PowerFlex compute-only nodes with VMware ESXi, click Block > Hosts.

Prerequisites

To facilitate powering on the PowerFlex appliance later, document the location of the management infrastructure VMs on their respective hosts. Also, verify that all startup configurations for the Cisco and Dell devices are saved.

See the Dell VxBlockTM System 1000 and PowerFlex Physical Planning Guide for information about power specifications.

Steps

  1. Check PowerFlex health and rebuild status:
    1. Log in to the PowerFlex Manager and check the dashboard.
    2. Confirm there is no error and rebuild or rebalance is running.
  2. Shut down all the customer VMs on the PowerFlex production cluster other than the SVMs:
    1. Using the VMware vSphere Client, log in to the customer VMware vCenter or a single VMware vCenter (production cluster).
    2. Expand the production clusters.
    3. Shut down all VMs, except for the PowerFlex storage VMs (SVM).
      CAUTION:Do not shut down the SVMs. Shutting them down now can result in data loss.
