Replacing a faulted storage processor assembly
Rev. 02
October 2022

This document describes how to replace a faulted storage processor assembly in Unity 300/300F/350F/380/380F, Unity 400/400F/450F, Unity 500/500F/550F, and Unity 600/600F/650F systems.
Two storage processor (SP) assemblies are located at and removed from the rear of the disk processor enclosure (DPE). During this procedure you will transfer certain parts from the faulted SP into the replacement SP.

NOTE: This procedure involves storage processor (SP) reboots coordinated to ensure that at least one SP is running at all times. During an SP reboot, data will be unavailable to front- or back-end connections that are not duplicated on the peer SP.
WARNING: On a system with Data at Rest Encryption enabled, follow the standard process to replace faulted parts. Improperly removing hardware can cause data to be inaccessible.
Replacing the DPE and both SPs requires a special procedure since the keystore is tied to the hardware. Do not replace all three parts at once, rather retain an SP until the DPE is online before replacing it. If all hardware was replaced, restore the keystore from a backup.

Before you start

Before you begin this procedure, ensure that you have received the new part and have correctly identified its intended location in the system. Refer to your Unisphere Service section for instruction on how to identify failures, order new parts and handle hardware components.

NOTE: This procedure involves storage processor (SP) reboots coordinated to ensure that at least one SP is running at all times. During an SP reboot, data will be unavailable to front- or back-end connections that are not duplicated on the peer SP.

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)

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 .
• 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 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.

Handling disks
Disks are extremely sensitive electronic components. Always handle a disk gently, and observe the following guidelines:

• Follow the instructions described in Removing, installing, or storing replaceable units.
• Do not stack disks upon one another, or place them on hard surfaces.
• Make sure that the replacement disk has the same part number or the part number of an approved replacement for the faulted disk. The part number (PN005xxxxxx) appears on the disk. A replacement disk should be the same type (example: SAS, FLASH) and have the same capacity (size and speed) as the disk it is replacing.
• When removing a spinning disk, pull the disk partially out of the slot, then wait 30 seconds for the drive to spin down before removing it.
• When installing multiple disks in a powered up system, wait at least 10 seconds before sliding the next disk into position.
• Place disks on a soft, antistatic surface, such as an industry-standard antistatic foam pad or the container used to ship the disk.

Standard touch point colors
Touch points are component locations where you can:

• Grip the hardware to remove or install a component.
• Open or close a latch.
• Turn a knob to open, close, or adjust a component.

Standard touch point colors are terra-cotta (orange) or blue.
NOTE: Within this documentation, the color orange is used instead of terra-cotta for simplicity.

Table 1. Standard touch point colors

Terra-cotta (orange)

| This color indicates that you can perform the task, such as remove a component with a terra- cotta (orange) lever, while the system remains powered (up/on).

NOTE: Some tasks may require additional steps.

Blue

| This color indicates that a shutdown of the system or component is required before you can perform the task, such as removing a component with a blue lever.

NOTE: Unity XT 380/380F systems that are manufactured in the second half of 2022 and later will not include the two 10 GbE ports. For more information, see the Dell Unity XT: Introduction to the Platform – A Detailed Review white paper on Online Support.

Replacing the faulted storage processor assembly

Take the following actions to remove the faulted storage processor assembly and install the replacement storage processor assembly into the system.

Removing an SP assembly
This procedure describes how to remove an SP assembly from the enclosure. There are two SP assemblies. The top SP assembly is considered to be “upside- down” and will mirror the bottom SP assembly. The illustration shows removal of the top SP assembly. The procedure for removing the bottom SP assembly is the same.

Prerequisites
Locate the faulted SP assembly with the amber Fault LED.

About this task

NOTE: DO NOT REMOVE an SP assembly while the “Unsafe to remove SP” LED shown below is lit.

Steps

1. Rotate the power cord bail to the right (left for bottom power supply). Disconnect the AC power cord from the power supply.
   NOTE: If the I/O module and network cables are not already labeled, label them clearly for reconnecting them later.
