Preface As part of an improvement effort, revisions of the software and hardware are periodically released. Some functions that are described in this document are not supported by all versions of the software or hardware currently in use. The product release notes provide the most up-to-date information about product features. Contact your technical support professional if a product does not function properly or does not function as described in this document.
1 Introduction Use the procedures in this document to power off or reboot your PowerStore appliances, nodes, or cluster gracefully. As part of a robust disaster recovery plan, it is recommended that you print and follow this procedure to test the planned shutdown and restart procedures.
Power control procedures preview The following table provides a preview of the steps that are required to power off or up the relevant component in your cluster: Table 1. Power control procedures preview Component Action PowerStore T model PowerStore X model Node Power off Use PowerStore Manager. Use VMware vCenter server. Or Run a service script. Power on ● If the node was removed from the chassis, reseat the node into the chassis, and reconnect its power cable.
2 Power control procedures This chapter contains the following topics: Topics: • • • • • • • Powering off procedures for PowerStore node Powering on procedures for PowerStore node Rebooting procedures for a PowerStore node Powering off procedures for PowerStore appliances Powering on procedures for PowerStore appliances Powering off procedures for PowerStore cluster Powering on procedures for PowerStore cluster Powering off procedures for PowerStore node This section includes the following procedures: ●
Next steps To verify that the node has powered off, check the status of the LEDs in the rear of chassis. Other than the LEDs for the power supply unit, management port, and service port, all LEDs on the node must be OFF. The Unsafe to Remove LED on the active or peer node is ON. Power off a PowerStore T model node using a service script Prerequisites Obtain the following information: ● Management IP address of the appliance that contains the node.
Steps 1. Disable support notifications as described in Disable support notifications on page 19. 2. Log in to the associated vCenter server. 3. If there are user VMs that are not configured for automatic migration to the ESXi host of the peer node, migrate them manually. 4. If there are user VMs that cannot migrate to the ESXi host of the peer node, shut them down manually. 5. Place the ESXi host for the PowerStore X model node in Maintenance Mode.
Power on a PowerStore T model node by reseating the node About this task Use the following procedure to power on (power up) a PowerStore T model node when it was removed from the chassis: Steps 1. Reseat the node into the chassis. The node will power on automatically. 2. Reconnect the power cable. 3. Wait for the node to complete powering on. 4. If you are running PowerStore OS Version 1.0.2.0.5.003 or lower, enable support notifications as described in Enable support notifications on page 19.
Steps 1. Reseat the node into the chassis. The node will power on automatically. 2. Reconnect the power cable. 3. Wait for the ESXi host for the node to complete powering on. 4. Log in to the associated vCenter server, and exit the ESXi host for the node from Maintenance Mode. The controller VM powers on automatically. NOTE: For primary internal M.2 boot module replacements, skip this step.
● Management IP address of the appliance that contains the node. In PowerStore Manager, go to Settings > Networking > Networking IPs > Management. Review the Management IPs table to identify the management IP address associated with the appliance. ● Service account credentials 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.
8. 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. 9. Monitor the vCenter server console to ensure that the ESXi host and controller VM have returned to normal operation. 10. Enable support notifications as described in Enable support notifications on page 19.
3. Enter the username and password that is associated with the service account, and log in. 4. Run the following command to power off the appliance: svc_appliance shutdown 5. Check the status of the LEDs in the rear of chassis to verify that the appliance has powered off. Other than the LEDs for the power supply unit, management port, and service port, all other LEDs on the appliance must be OFF. 6. Disconnect the power cables from the base enclosure and expansion enclosures, if required.
3. If applicable, reconnect the power cables to each associated expansion enclosure in an ascending order, such as the following: ● Expansion enclosure 0 ● Expansion enclosure 1 ● Expansion enclosure 2 The power status LEDs on each expansion enclosure turns on when the power cable is connected. 4. Reconnect the power cables to node A first, and then node B. The Node Power LEDs on both nodes turn on when the power cable is connected. 5.
● Power off a PowerStore T model cluster on page 16 ● Power off a PowerStore X model cluster on page 16 Power off a PowerStore T model cluster 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. ● When the cluster is powered off, you have no access to the GUI, API, or CLI interfaces.
○ Address of the VMware vCenter server associated with the appliance ○ Associated vCenter server account credentials About this task NOTE: In this release, you can only have one appliance in a PowerStore X model cluster. Use the following procedure to power off (power down) a PowerStore X model cluster: Steps 1. Disable support notifications as described in Disable support notifications on page 19. 2. Log in to the associated vCenter server. 3.
● ● ● ● Address of the VMware vCenter server associated with the appliance. Associated vCenter server account credentials Service tags of the appliance and, if applicable, the associated expansion enclosures. Management IP address of the cluster and the service account credentials About this task Use the following procedure to power on a PowerStore X model cluster: Steps 1. If nodes were removed, reseat the nodes back into the base enclosure chassis. 2.
A Support Notifications Learn how to disable and enable support notifications. Topics: • • Disable support notifications Enable support notifications Disable support notifications To avoid unnecessarily alerting Customer Support of an outage, disable support notifications before starting procedures that disconnect a node by powering down or rebooting. Steps 1. In PowerStore Manager, go to Settings > Support > Disable Support Notifications. 2. Click the checkbox for the appliance that you are servicing.
