Handling Field Replaceable Units (FRUs)
This section describes precautions you must take and generalprocedures 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 alltimes. 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:
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 theprocedures in the section
procedures (without an ESD kit)
.
Emergency
Use the ESD wristband that is supplied with your system.
EMC CONFIDENTIALversion: 4.5
4 of 51
EMC®VNX™Procedure Generator
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 designedshipping 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 CONFIDENTIALversion: 4.5
5 of 51
EMC®VNX™Procedure Generator
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
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.

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
# /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

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
where <server_name> is the name of the server. Use the nas_server –list command to get
the server name.
Example:
EMC CONFIDENTIALversion: 4.5
14 of 51
EMC®VNX™Procedure Generator
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.
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
# /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.
/nas directory.
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:
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.

/nas/sbin/nas_connecthome –i
15. [ ] For each enabled connection, verify that ConnectHome works:
/nas/sbin/nas_connecthome –test connection_name
For example:
/nas/sbin/nas_connecthome -t -email_1
or
/nas/sbin/nas_connecthome -t -email_2
or
/nas/sbin/nas_connecthome -t –https
or
/nas/sbin/nas_connecthome -t -modem_1
16. [ ] 4. Verify email notifications is configured:
/nas/bin/nas_emailuser –info
17. [ ] If the Recipient Address(es) field is empty, email notifications has not been configured and does
not need to be enabled. If you want to configure email notifications, use the
/nas/bin/nas_emailuser command or Unisphere to configure it.
18. [ ] If the
Recipient Address(es) field is populated, email notifications was enabled. Re-enable email
