Power off an appliance

Prerequisites

  • Do not power off the appliance if you are replacing a hardware component. Identify the node that includes the faulted hardware component, and power off only that node. For more information, see Power off a node using PowerStore Manager.
  • Powering off an appliance results in the mapped hosts losing access to the data on the appliance. Before you begin, ensure that you temporarily disconnect host access from all storage resources.
  • Obtain the following information:
    • Management IP address of the appliance. In PowerStore Manager, go to Settings > Networking > Network IPs > Management. Review the Management IPs table to identify the management IP address associated with the appliance.
    • Service account credentials
    • Service tags of the appliance
    • If applicable, service tags of the associated expansion enclosures

      svc_cluster_management MovePrimaryAppliance -n <ID number of new primary node>
  4. In PowerStore Manager, under Hardware, select the appliance that you want to power off.
