CAUTION: Do not vMotion the vCLS VMs. b. Place the ESXi host on the secondary node of the appliance into maintenance mode. The controller VM is automatically powered off, and the vCLS VMs on the ESXi host are automatically migrated to another host. NOTE: If the ESXi host is unable to enter maintenance mode because of the vCLS VMs, manually power off the vCLS VMs to force the VMs to migrate to another host. c. Create a folder of the type New Host and Cluster Folder on the Datacenter. d. Move the ESXi host on the secondary node of the appliance to the new folder on the Datacenter. e. Take the ESXi host out of maintenance mode and power on the controller VM. 9. Wait 15 minutes, and then ensure that the secondary node is up and running in PowerStore Manager. Ensure that there are no active alerts on the secondary node: a. Under Hardware, select Appliances, and select the appliance that you want to remove. b. Select the Components card, select the Rear View tab. c. Expand BaseEnclousure, select the secondary node, and ensure that there are no active alerts. In addition, go to Monitoring > Events in PowerStore Manager and ensure that the following event is displayed for the secondary node: Event: NODE_IO_SERVICE_LEVEL. Event text: IO service level of the node has changed to ready 10. Perform the following steps on the vCenter Server to exclude the ESXi host on the primary node of the appliance from the ESXi cluster: a. If there are user VMs on the primary node of the appliance, vMotion the user VMs to another appliance in the cluster. CAUTION: Do not vMotion the vCLS VMs. b. Place the ESXi host on the primary node of the appliance into maintenance mode. The controller VM is automatically powered off, and the vCLS VMs on the ESXi host are automatically migrated to another host. NOTE: If the ESXi host is unable to enter maintenance mode because of the vCLS VMs, manually power off the vCLS VMs to force the VMs to migrate to another host. c. Move the ESXi host on the secondary node of the appliance to the new folder on the Datacenter, which was created in step 9. d. Take the ESXi host out of maintenance mode and power on the controller VM. 11. Wait 15 minutes, and then ensure that the primary node is up and running in PowerStore Manager. Ensure that there are no active alerts on the primary node in PowerStore Manager: a. Under Hardware, select Appliances, and select the appliance that you want to remove. b. Select the Components card, select the Rear View tab. c. Expand BaseEnclousure, select the primary node, and ensure that there are no active alerts. In addition, go to Monitoring > Events in PowerStore Manager and ensure that the following event is displayed for the primary node: Event: NODE_IO_SERVICE_LEVEL. Event text: IO service level of the node has changed to ready 12. Ensure that Node A is the primary node on the appliance to be removed. The factory reset of the appliance cannot occur unless Node A is the primary node of the appliance. a. Under Hardware, select Appliances, and select the appliance that you want to remove. b. Select the Components card, select the Internal View tab. c. Ensure that Node A is the primary node on the appliance. If the Node B is the primary node of the appliance, log in to the appliance using an SSH client and run the svc_node reboot local command to reboot Node B and make Node A the primary node. 13. If there still are storage objects on the appliance to be removed, use PowerStore Manager to migrate the storage objects to another appliance in the cluster or remove the storage objects from the appliance. 14. Remove the appliance from the PowerStore X model cluster using PowerStore Manager. a. Under Hardware, select Appliances. 188 Remove appliances from the cluster
