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.
Topics:

• Power control procedure considerations
• Power control procedures preview

Power control procedure considerations
Note the following before you get started:

• Powering off a node, appliance, or cluster can take several minutes to complete.

• In a true emergency power off situation, turn the cabinet power switches to the off position to immediately remove power from the all cabinet components.

• Working with hardware may cause electrostatic discharge that could damage your hardware. Before working with any hardware, take precautions around handling replaceable units. See Safety precautions for handling replaceable units on page 20.

• If you are relocating or replacing hardware, to help identify associated enclosures when you are ready to cable and power on:
  ○ Ensure that you make a note of the cabling between enclosures and the appliances. If you used cable labels at the time of initial installation, reconnecting the cables is easier.
  ○ Ensure that you also record the Dell Service Tag of each enclosure in your cluster.

• A PowerStore X model appliance consists of two ESXi host nodes (node A and node B), running VMware ESXi version 7.0.3, and a controller VM on each that runs the PowerStore operating environment. Powering off a PowerStore X model node or cluster requires operations in the associated VMware vCenter server. See the VMware documentation for more information about the vCenter server commands.

• Nodes in the appliance power on into the same mode they were in before the appliance was powered off. If a node powers on in service mode:
  1. Log in to the appliance from an SSH client.
  2. Run the s v c r e s c u e s t a t e c l e a r command to clear the boot mode.
  3. Run the s v c n o d e r e b o o t command.
  ○ For a PowerStore T model node, this command reboots the node itself.
  ○ For a PowerStore X model node, only the PowerStore controller VM gets rebooted.
  Once rebooted, the node returns to normal mode.
  NOTE: The s v c n o d e service script, with r e b o o t and s h u t d o w n arguments, is typically used in the context of rebooting or powering off a PowerStore T model node.
  Use the VMware vCenter server commands to reboot or power off a PowerStore X model node. In PowerStore X model nodes, running the s v c n o d e service script with r e b o o t or s h u t d o w n arguments only affects the PowerStore controller VM.
  Unless specifically directed by your service provider, for PowerStore X model appliances, use the s v c n o d e service script only for the following purposes:
  ○ Go out of service mode ( r e b o o t argument).
  ○ Power on the node ( p o w e r _ o n argument).
  For more information about the service scripts, see the PowerStore Service Scripts Guide.

• If both nodes in an appliance reboot in service mode, always return Node A to normal mode first to avoid management software conflicts. After Node A is operating normally, you can return Node B to normal mode.

• Before powering down an appliance with metro volumes, ensure that the role of the metro volumes on the appliance are all set to non-preferred. Refer to the Protecting Your Data guide for details about setting metro volume roles.

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.
Avoiding electrostatic discharge (ESD) damage
When replacing or installing hardware units, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them.
Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, run a humidifier in the work area to help decrease the risk of ESD damage.
Follow these procedures to prevent equipment damage:

• Provide enough room to work on the equipment.

• Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.

• Do not remove replacement or upgrade units from their antistatic packaging until you are ready to install them.

• Before you begin service, gather together the ESD kit and all other materials you need.

• Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.

• Use ESD anti-static gloves or an ESD wristband (with strap).
  If using an ESD wristband with a strap:
  ○ Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinet/rack or enclosure.
  ○ Wrap the ESD wristband around your wrist with the metal button against your skin.
  ○ If a tester is available, test the wristband.

• If an emergency arises and the ESD kit is not available, follow the procedures in Emergency Procedures (without an ESD kit).

Emergency procedures (without an electrostatic discharge kit)
In an emergency when an electrostatic discharge (ESD) kit is not available, use the following precautions to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.
NOTE: These precautions are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.

• Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or enclosure.
• Before removing any unit from its antistatic bag, place one hand firmly on a bare metal surface of the cabinet/rack or enclosure, and at the same time, pick up the unit while it is still sealed in the antistatic bag. At the same time, do not move around the room or touch other furnishings, personnel, or surfaces until you have installed the unit.
• When you remove a unit from the antistatic bag, avoid touching any electronic components and circuits on it.
• If you must move around the room or touch other surfaces before installing a unit, first place the unit back in the antistatic bag. When you are ready again to install the unit, repeat these procedures.

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.

Transit/storage environment| Operating environment temperature| Acclimation time
---|---|---
Temperature| Humidity|
Nominal 68-72°F (20-22°C)| Nominal 40-55% RH| Nominal 68-72°F (20-22°C) 40-55% RH| 0-1 hour
Cold <68°F (20°C)| Dry <30% RH| <86°F (30°C)| 4 hours
Cold <68°F (20°C)| Damp 30% RH| <86°F (30°C)| 4 hours
Hot >72°F (22°C)| Dry <30% RH| <86°F (30°C)| 4 hours
Hot >72°F (22°C)| Humid 30-45% RH| <86°F (30°C)| 4 hours
Humid 45-60% RH| <86°F (30°C)| 8 hours
Humid 60% RH| <86°F (30°C)| 16 hours
Unknown| <86°F (30°C)| 16 hours

• If there are signs of condensation after the recommended acclimation time has passed, allow an additional 8 hours to stabilize.
• Systems and components must not experience changes in temperature and humidity that are likely to cause condensation to form on or in that system or component. Do not exceed the shipping and storage temperature gradient of 45°F/hr (25°C/hr).

Removing, installing, or storing replaceable units
Use the following precautions when removing, handling, or storing replaceable units:
CAUTION: Some replaceable units have the majority of their weight in the rear of the component. Ensure that the back end of the replaceable unit is supported while installing or removing it. Dropping a replaceable unit could result in personal injury or damage to the equipment.
NOTE: For a module that must be installed into a slot in an enclosure, examine the rear connectors on the module for any damage before attempting its installation.
CAUTION: A sudden jar, drop, or even a moderate vibration can permanently damage some sensitive replaceable units.

• Do not remove a faulted replaceable unit until you have the replacement available.

• When handling replaceable units, avoid electrostatic discharge (ESD) by wearing ESD anti-static gloves or an ESD wristband with a strap. For additional information, refer to Avoiding electrostatic discharge (ESD) damage on page 20.

• Avoid touching any exposed electronic components and circuits on the replaceable unit.

• Never use excessive force to remove or install a replaceable unit. Take time to read the instructions carefully.

• Store a replaceable unit in the antistatic bag and the specially designed shipping container in which you received it. Use the
  antistatic bag and special shipping container when you need to return the replaceable unit.

• Replaceable units must acclimate to the operating environment before applying power. This requires the unpackaged component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation. Refer to Hardware acclimation times on page 21 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. Also, each slot should contain a component or filler panel to ensure proper air flow throughout the system.
Unpacking a part
Use these best practices to unpack a part.
Steps

1. Wear ESD gloves or attach an ESD wristband to your wrist and the enclosure in which you are installing the part.
2. Unpack the part and place it on a static-free surface.
3. If the part is a replacement for a faulted part, save the packing material to return the faulted part.
