Handling Field Replaceable Units (FRUs)

This section describes precautions you must take and general procedures you must follow when removing,

installing, or storing field-replaceable units (FRUs). The procedures in this section apply to FRU handling

during hardware upgrades as well as during general replacement.

FRUs and Power Issues

FRUs are designed to be powered up at all times. This means you can replace FRUs and accomplish most

hardware upgrades while the cabinet is powered up. To maintain proper airflow for cooling and to ensure

EMI compliance, make sure all front bezels, filler panels, and filler modules are reinstalled after the FRU

replacement or hardware upgrade is completed. Do not remove a faulty FRU from the system until you have

a replacement available.

CAUTION: When you want to power down a storage processor enclosure (SPE), turn off the power

switch on the enclosure’s standby power supply (SPS). Never turn off the SPE’s power supply

switches. Turning off the SPE power supply switches instead of the SPS power switch shuts down

the storage processors before they have enough time to save the write-cache data to the vault

drives. This causes data loss.

If write-cache data is not saved, the storage processor log displays an error message similar to the

following:

Enclosure 0 Disk 5 0x90a (Can’t Assign - Cache Dirty) 0 0xafb40 0x14362c.

If you see this error message, contact Customer Service immediately.

Avoiding Electrostatic Discharge (ESD) damage

When replacing or installing FRUs, 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, running a humidifier in the work area helps

decrease the risk of ESD damage. You must use the following procedures to prevent damage to the

equipment, so read the following instructions carefully.

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 FRUs from their antistatic packaging until you are ready to

install them.

Gather the ESD kit and all other materials you will need before you service a component. Once

servicing begins, you should avoid moving away from the work site; otherwise, you may build up an

electrostatic charge.

Use the ESD kit when handling any FRU.

If an emergency arises and the ESD kit is not available, follow the procedures in the section Emergency

procedures (without an ESD kit).

Use the ESD wristband that is supplied with your system.

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

5 of 51

To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal on the cabinet

enclosure; then secure the wristband around your wrist with the metal button against your skin.

Emergency procedures (without an ESD kit)

In an emergency, when an ESD kit is not available, use the following procedures to reduce the possibility of

an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic

potential.

IMPORTANT: These procedures are not a substitute for the use of an ESD kit. You should follow them

only in the event of an emergency.

Before touching any FRU, touch a bare (unpainted) metal surface of the enclosure.

Before removing any FRU from its antistatic bag, place one hand firmly on a bare metal surface of the

enclosure, and at the same time, pick up the FRU while it is still sealed in the antistatic bag. Once you

have done this, do not move around the room or contact other furnishings, personnel, or surfaces until

you have installed the FRU.

When you remove a FRU 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 FRU, first place the FRU

back in the antistatic bag. When you are ready again to install the FRU, repeat these procedures.

Removing, installing, or storing FRUs

Use the following precautions when you remove, handle, or store FRUs:

Do not remove a FRU from the cabinet until you have the replacement available.

Handle a FRU only when wearing a properly attached ESD wristband:

Attach the clip of the ESD wristband to the ESD bracket or to a bare metal portion of the FRU’s

enclosure.

Secure the wristband around your wrist with the metal button against your skin.

Handle a FRU gently. A sudden jar, drop, or vibration can permanently damage some FRUs.

The weight of some FRUs is not evenly distributed. To prevent personal injury or equipment damage

when removing, installing, or handling theses FRUs, use both hands and provide extra support at the

heavy end of the FRU.

Never use excessive force to remove or install a FRU.

Store a FRU in the antistatic bag and the specially designed shipping container in which you received it.

Use this special shipping container when you need to return the FRU.

If you need to store a FRU for a short time, make sure the temperature of the location where you store

FRU is within the limits specified by the FRU’s Technical Specifications.

Disk modules are sensitive to the extreme temperatures sometimes encountered during shipping. We

recommend that you leave a new disk modules in its shipping container and allow it to acclimate to the

installation site’s ambient temperature for at least four hours before operating the new module in the

system.

When removing a disk module, pull the module part way out of the slot, then wait 30 seconds for the

drive to spin down before removing it.

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

When installing multiple disks in a powered-up system, wait at least 6 seconds before sliding the

second and each subsequent disk into the system.

Place a disk module on a soft, antistatic surface, such as an industry-standard antistatic foam pad or

the container used to ship the module. Never place a disk module directly on a hard surface.

WARNING: The weight of some FRU assemblies is not evenly distributed. To prevent personal

injury or equipment damage when handling FRU assemblies, make sure you provide extra support

at the heavy end of a FRU assembly.

Replacing a Blade Enclosure (DME)

This procedure explains how to replace a Blade enclosure (aka, Data Mover, DME). The tasks apply to

DMEs in VNX5300 through 7500 models with VNX for File systems.

CAUTION: Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry.

Always follow ESD prevention procedures when removing and replacing Customer-Replaceable

Units (CRUs) and Field-Replaceable Units (FRUs).

Task Summary

This procedure assumes that you are reinstalling (transferring) the power/cooling modules, management

modules, Blades, and I/O modules from the faulted Blade enclosure to the replacement Blade enclosure.

So that you can understand what is involved, the table of Contents lists the high-level tasks required for this

procedure. Take a moment to become familiar with these tasks. If you have any questions, contact

Customer Support before you begin the procedure.

CAUTION: This procedure takes approximately three hours to complete. During this time, the NAS

service is stopped and service is disrupted. Any process initiated by the Control Station (CS) or

any commands run from the /nas directory is inhibited. You cannot manage the system during this

time.

Note: This procedure shows command output collected from a two X-Blade (Blade) system, unless

otherwise specified. Be aware that the actual command output will differ depending on the number of

Blades in the system. Additionally, output values displayed in the document are for the specific system used

to create this procedure.

WARNING: The weight of some FRU assemblies is not evenly distributed. To prevent personal

injury or equipment damage when handling an assembly, make sure you provide extra support at

the heavy end of the assembly.

Task 1: Diagnose and identify Faulted FRU

There are multiple ways to diagnose and identify a faulted FRU component. Follow the instructions below to

diagnose a problem with an FRU:

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

7 of 51

Receive an email notification

If the system detects a problem with an internal component, the system may send an email notification

outlining the problem detected and recommending steps to correct the problem. If you receive an email

notification, follow the recommended steps described in the email.

You can log in to Unisphere to diagnose a problem with a hardware component. Do the following:

1. [ ] Open Unisphere in an Internet browser using the following URL:

https://<control_station>

where <control_station> is the hostname or IP address of the primary Control Station (CS).

a. At the login prompt, log in as sysadmin. The default password is sysadmin.

b. Set the scope to Global.

After logging in, the Unisphere Dashboard page appears. Unisphere displays the system’s hardware

component status and the alerts for managed systems on the Dashboard. You can right-click on any

new alert in the Alerts quadrant and select Details to view the associated error message.

Note: Alerts will not automatically clear. Delete old alerts by right-clicking on the alert and selecting

Delete.

2. [ ] Use the drop-down list at the top left of the Dashboard to select the system that contains faulted

hardware.

3. [ ] Select System > Hardware > Hardware for File to view information about the hardware

components.

4. [ ] Check the system inventory for faulted hardware components.

5. [ ] Record the full component name for any faulted hardware found on the Hardware for File page.

The component name contains important information about hardware location.

For example, a Blade enclosure is listed in Unisphere as DME 0, where 0is the Blade enclosure (DME)

number.

Check the Fault LED

To check the fault LEDs found on the front of the system, you must remove the front bezel to expose them

and then check for faulted components.

6. [ ] Turn the key at the front of the bezel enclosure counterclockwise.

7. [ ] Press the latches on the front of the bezel, and pulling the bezel toward you (Figure 1).

Check the Blade enclosure fault LEDs

If you are near the front of the system, you can easily check the Blade enclosure fault LED.

8. [ ] Locate the Blade enclosure.

For a multi-Blade enclosure system, if you recorded the information listed in Unisphere during the

previous task, find the faulted Blade enclosure using the management module seven-segment LED on

the rear of each Blade enclosure and the recorded fault information.

9. [ ] Check the Blade enclosure fault LED. Figure 2 shows the LEDs visible for the Blade enclosure

from the front of the Blade enclosure.

10. [ ] If a Blade enclosure LED or Unisphere show a faulted Blade enclosure, continue with this

replacement procedure.

11. [ ] If each Blade enclosure LED or Unisphere does not show a faulted Blade enclosure, it does not

need to be replaced.

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

Recheck the Unisphere to see if another component has faulted. If the Unisphere shows another

component has faulted, it might need to be replaced instead of a Blade enclosure.

Task 2: Disabling ConnectHome and Email Notifications

For VNX OE for File 7.0 or later, use a HyperTerminal or PuTTY session to disable ConnectHome:

12. [ ] From the root directory, disable ConnectHome:

/nas/sbin/nas_connecthome -service stop

13. [ ] Disable the email notification service:

/nas/bin/nas_emailuser -modify -enabled no

14. [ ] Verify that the email notification service has stopped (is not enabled):

/nas/bin/nas_emailuser –info

15. [ ] ConnectHome and email notifications are now disabled on your VNX OEFile system. Skip over the

next Block task to begin the service activity.

Task 3: Saving Resume PROM Configuration Information

Save the Resume PROM configuration information for the faulted Blade enclosure (BE). You use this

information later to reconfigure the replacement enclosure.

1. [ ] Open the enclosure_resume.enclosure_<Blade_enclosure_number>.xml file located

in /nas/log directory.

where <Blade_enclosure_number> is the ID (0, 1, 2, or 3) of the faulted BE.

Table 1 lists the BEs associated with each enclosure.

Table 1 Blade Enclosure ID and Blade mapping

Task 4: Halting the Secondary Control Station

If your system is a dual Control Station system, the secondary CS (CS 1) must be stopped before NAS

services on the primary CS are stopped; otherwise, the secondary CS will takeover. If your system does not

have dual Control Stations (CS 0 and CS 1), skip this section.

Note: If the secondary CS is currently acting as the primary CS, you may need to failback and then

continue to power down the secondary CS.

This task halts the secondary control station:

1. [ ] At the rear of the cabinet, connect the null modem cable from a serial port on your management

console to the secondary Control Station, CS 1.

2. [ ] Open the HyperTerminal or PuTTY session using the following settings:

Bits per second: 19200

8. [ ] Disconnect the CS 1 power cable from the power distribution panel (PDP).

9. [ ] Close the HyperTerminal or PuTTY session with CS 1.

10. [ ] Reconnect your management console to the serial port on CS 0 and reopen the HyperTerminal or

PuTTY session on CS 0 using the settings found in Step 2.

11. [ ] The secondary CS is halted and powered off.

Task 5: Prepare for Replacement

To prepare a faulted BE for removal from the system, its internal components must be halted and removed.

This section provides steps for preparing the system for the replacement of a BE.

Note: This document uses the term Blade to refer to a component that is defined as a logical construct of a

CPU module with its associated I/O modules.

Follow the procedure that best matches the system’s Blade configuration to prepare the system for the BE

replacement:

Multi-Blade system

Single-Blade system

Multi-Blade system

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

13 of 51

Single-Blade system

For a single-Blade system, prepare the Blade for removal by doing the following:

1. [ ] Unmount the file systems and prepare the Blade to be halted by typing:

# /nas/bin/server_cpu server_2 -q now

2. [ ] Stop the NAS service on the primary CS by entering:

CAUTION: Stopping the NAS service disrupts service on the system. Any process initiated

by the Control Station or any commands run from the /nas directory are inhibited. Do not to

attempt to run this command while working in the /nas directory.

# /sbin/service nas stop

This command takes up to five minutes to complete. If this command fails, reboot the CS and try

again.

3. [ ] Halt the Blade by typing:

CAUTION: When you shut down the Blade, you will lose access to the public networks and file

systems. Verify that the customer is prepared for this action.

# /nasmcd/sbin/t2reset pwroff -s 2

4. [ ] Wait three minutes for the previous command to complete and then verify that the Blade has

powered off:

Note: The getreason command can be augmented to provide continuous monitoring of the system

reason codes by adding the watch command. Use Ctrl/C to stop end the monitoring. For example # watch

/nasmcd/sbin/getreason

Example Output:

# /nasmcd/sbin/getreason

6 - slot_0 primary control station

- slot_2 powered off

5. [ ] Remove the enclosure from the NAS database:

# /nasmcd/sbin/setup_enclosure -removeEnclosure 0

6. [ ] The BE is removed from the NAS database and the NAS service is stopped.

Disconnect the faulted Blade enclosure's two power cables from the rack.

Multi-Blade system

For a multi-Blade system, prepare the Blade enclosure for removal by doing the following:

1. [ ] Determine the failover status of the Blades by entering:

# /nas/bin/nas_server -info –all

Sample Output:

id = 1

name = server_2.faulted.server_3

status Whether the Blade is enabled or disabled, and whether it is active.

2. [ ] Go to Step 4 if the system is configured with only one Blade enclosure, otherwise continue.

3. [ ] For a multi-Blade enclosure system, prepare each Blade in the faulted BE for removal. Repeat this

step for each Blade in the faulted enclosure before continuing to the next step.

a. If the Blade is a primary Blade and has no standby Blade configured, no action is required.

b. If the Blade is a primary Blade that has a standby Blade configured in another BE, failover to that

standby Blade:

# /nas/bin/server_standby <server_name> -activate mover

Where <server_name> is the name of the server. Use the nas_server –list command to get

the server name.

c. If the Blade is configured as a standby Blade and is currently standing in for an available primary Blade

contained in another BE, enter the following command:

# /nas/bin/server_standby <server_name> -restore mover

where <server_name> is the name of the server. Use the nas_server –list command to get

the server name.

Example:

EMC®VNX™Procedure Generator

EMC CONFIDENTIAL version: 4.5

15 of 51

In a four Blade system with BE 1 faulted, Blade 2 has failed over to Blade 4, its standby. The

command to restore Blade 2 as the primary Blade is:

# /nas/bin/server_standby server_2 -restore mover

d. If the Blade is configured as a standby Blade and is not currently standing in for a primary Blade

contained in another BE, remove the Blade as a standby. Enter the following command:

Note: A Blade can be configured as a standby for multiple primary Blades. Repeat this step for each

primary Blade for which the Blade is a standby. Afterwards, go to step 4.

# /nas/bin/server_standby <server_name> -delete mover

where <server_name> is the name of the primary Blade. Use the nas_server -list command to get

the Blade name.

4. [ ] Stop the NAS service by entering:

CAUTION: Stopping the NAS service disrupts service on the system. Any process initiated by

the Control Station or any commands run from the /nas directory is inhibited. Do not to

attempt to run this command while working in the /nas directory.

# /sbin/service nas stop

This command will take up to five minutes to complete. Make sure it is finished before you continue. If

this command fails, reboot the CS and try again.

5. [ ] Power off each Blade in the faulted BE:

CAUTION: When you shut down a Blade in a single BE system, you will lose access to the

public networks and file systems. Verify that the customer is prepared for this action.

# /nasmcd/sbin/t2reset pwroff -s <slot_number>

Where <slot_number> is the slot ID number of the Blade inside the BE.

6. [ ] Wait three minutes for the previous commands to complete and then verify that the Blades have

powered off:

Note: The getreason command can be augmented to provide continuous monitoring of the system

reason codes by adding the watch command. Use Ctrl/C to stop the monitoring. For example, watch

/nasmcd/sbin/getreason.

Example:

6 - slot_0 primary control station

- slot_2 powered off

- slot_3 powered off

7. [ ] Remove the enclosure from the NAS database:

#/nasmcd/sbin/setup_enclosure -removeEnclosure <Blade_enclosure_number>

where <Blade_enclosure_number> is the BE number (shown on the LED display on the

management modules) of the faulted BE.

8. [ ] The BE is removed from the NAS database and the NAS service is stopped. Disconnect the faulted

Blade enclosure's two power cables from the rack.

Task 6: Remove Faulted DME

You should remove the faulted chassis with all its components installed. After you install the replacement

chassis in the cabinet, you must transfer the components from the faulted chassis to the replacement

chassis. This process helps to ensure the correct placement of the components.

CAUTION: The enclosure is heavy and should be installed into a rack by two people (or a

data-center lift tool). To avoid personal injury and/or damage to the equipment, do not attempt to lift

and install the enclosure without a mechanical lift or help from another person.

1. [ ] Remove four M5 12.7 mm screws (two per side) to release the chassis from the cabinet (Figure 4).

Note: The screws also secure the latch brackets mounted on the front of the chassis.

Transfer Components to the Replacement DME

You must transfer the power/cooling modules, CPU modules, management modules, and I/O modules from

the faulted chassis to the corresponding locations in the replacement chassis. Use the procedures in the

sections that follow to transfer these components.

You must transfer the power/cooling modules and the CPU modules from the faulted chassis to the same

locations in the replacement chassis one component at a time. Transfer components from the A side first

(from the rear of the system, this is the right side), then transfer components from the B side (from the rear

of the system, this is the left side).

For each Blade, starting with the components on the A side (from the front of the system, this is the left side),

complete the following steps, as described in the sections that follow, to transfer the power/cooling modules

and the CPU modules:
