Reboot a PowerStore X model node Prerequisites Obtain the following information: ● Address of the VMware vCenter server associated with the appliance ● Associated vCenter server account credentials Ensure that SSH is enabled on the ESXi host and configured to start automatically. NOTE: Do not power off or reboot a node, if the peer node is not operating normally. If the peer node is experiencing any major issues, associated alerts and events appear in PowerStore Manager. Also, to avoid service interruptions, ensure that there are sufficient and healthy paths from all connected hosts to the peer node. About this task Use the following procedure to reboot a PowerStore X model node: Steps 1. Log in to the associated vCenter server. 2. If there are user VMs that are not configured for automatic migration to the ESXi host of the peer node, migrate them manually. NOTE: vSphere Remote Office Branch Office Advanced does not support automatic migration. 3. If there are user VMs that cannot migrate to the ESXi host of the peer node, shut them down manually. 4. Place the ESXi host for the node in Maintenance Mode. VMware DRS starts to migrate user VMs to the ESXi host of the peer node, and then the PowerStore controller VM is powered off. 5. Monitor and ensure that all relevant user VMs migrate over to the ESXi host of the peer node. 6. Once all VMs are migrated over and node goes into Maintenance Mode, reboot the ESXi host using vCenter commands. 7. Monitor the vCenter server console to ensure that the ESXi host has rebooted, and then exit the ESXi host from Maintenance Mode. The controller VM powers on automatically. 8. Monitor the vCenter server console to ensure that the ESXi host and controller VM have returned to normal operation. Powering off procedures for PowerStore appliances This section includes the following procedures: ● Power off a PowerStore T model appliance on page 171 ● Power off a PowerStore X model appliance on page 172 Power off a PowerStore T model 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 PowerStore T model node using PowerStore Manager on page 166. ● 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: Power control procedures 171
