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 service provider 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. 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 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.
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. The controller VM powers on automatically once the ESXi host powers up because the ESXi host is not in the Maintenance Mode. 5.
About this task Use the following procedure to reboot a PowerStore T model node using a service script: Steps 1. Launch an SSH client, and connect to the appliance using the management IP address. 2. Enter the username and password for the service account to log in. The login prompt indicates the node that you are logged into. For example, the letter "A" in the prompt [SVC:user@FNM12345678910-A~]$ indicates that you are logged into node A. 3.
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 7. ● Powering off an appliance results in the mapped hosts losing access to the data on the appliance.
Steps 1. Log in to PowerStore Manager. 2. Use PowerStore Manager to identify VMs that utilize the iSCSI or FC store of the appliance. a. b. c. d. e. f. g. Select Storage > Storage Containers. Select the first Storage Container. Select Virtual Volumes. Select the Show Filters icon. Select Add Filter > Appliance. Identify the VMs that are using storage on the appliance and the VMs that are running on the appliance. Repeat these steps for each Storage Container. 3.
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.
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. Print the power on instructions to ensure that you have the information you require to power on the cluster in a specific order.
About this task Use the following procedure to power off a multiappliance PowerStore X model cluster. The following table describes which controller VMs must be manually powered off. The remaining controller VMs are automatically shut down when you place the ESXi host in Maintenance Mode. Table 2.
The Node Power LED on each node turns on when the power cable is connected. Power on a PowerStore X model cluster Prerequisites Obtain the following information: ● 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.
A Safety precautions for handling replaceable units Review these safety considerations before replacing any parts to avoid damage to your system. Topics: • Handling replaceable units Handling replaceable units This section describes the precautions that you must take and the general procedures that you must follow when removing, installing, and storing any replaceable unit.
Hardware acclimation times Units must acclimate to the operating environment before applying power. This requires the unpackaged system or component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation.
condensation. Refer to Hardware acclimation times on page 20 to ensure the replaceable unit has thermally stabilized to the operating environment. NOTE: Your storage system is designed to be powered on continuously. Most components are hot swappable; that is, you can replace or install these components while the storage system is running. However, the system requires that front bezels should always be attached to ensure EMI compliance. Make sure you reattach the bezel after replacing a component.
B 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.
