Power off a cluster using PowerStore Manager

Prerequisites

  • Powering off a cluster results in the mapped hosts losing access to the data on the cluster. Before you begin, ensure that you temporarily disconnect host access from all storage resources.
  • Check if any VMs are using the storage from the cluster. It is recommended to power off the VMs before powering off the cluster.
  • When the cluster is powered off, you have no access to the UI, API, or CLI interfaces. Print the power on instructions to ensure that you have the information you require to power on the cluster in a specific order. You can also find these instructions on dell.com/powerstoredocs.
  • Obtain the following information:
    • Management IP address of the cluster
    • Service account credentials
    • Site ID
    • Service tags of the appliances
    • If applicable, service tags of the associated expansion enclosures

Steps

  1. In PowerStore Manager, select the Settings icon, and then select Power Down in the Cluster section.
  2. Click Power Down Cluster.
    The Validation window opens.
  3. Click Perform validation.
  4. Review any errors, warnings, and recommendations. If the cluster passes all the validation checks, click Next. If there are remaining errors that can safely be ignored, select Ignore errors and proceed, regardless of possible data loss, and then click Next.
    The Active Objects window opens.
  5. Review the list of objects on the appliance that had I/O activity during the last five minutes.
  6. Click Next.
    The Confirm window opens.
  7. Enter the service password, and click Power Down.
  8. Check the status of the process by looking at the Node Power LEDs. The power off process is complete when the Node Power LEDs for all nodes in the cluster are off.
  9. After confirming that the cluster has shut down, disconnect the power cables from both nodes in one of the base enclosures in the cluster, if required. Wait a few seconds and confirm that all remaining LEDs have turned off.
  10. Disconnect the power cables from each of the associated expansion enclosures to power them down, if required.
  11. If your cluster has more than one appliance, repeat the previous two steps to disconnect power from the remaining appliances in the cluster.
