3 Deployment types
The following types of deployments are supported:
•Single domain
In a single domain deployment, one path exists from the disk enclosure to the host. In a single
domain deployment, only one I/O module in the disk enclosure is used
•Dual domain
In a dual domain deployment, two paths exist from the disk enclosure to the host. In a dual
domain deployment, both I/O modules in the disk enclosure are used. Because dual domain
deployments provide two paths to the storage, access is ensured, even in the event of device,
cable, or power failure. In dual domain environments, dual-port disk drives are required.
•Server attached (single or dual domain)
In a server attached deployment, the disk enclosure is connected to a controller card installed
in a server. Several models of controller cards are supported for use with this disk enclosure.
For more information, see the QuickSpecs for the disk enclosure.
•Controller enclosure attached (single or dual domain)
In a controller enclosure attached deployment, the disk enclosure is connected to a rack-mounted
array controller enclosure. The controller enclosure is then connected to the server or network.
Several models of array controller enclosures are supported for use with this disk enclosure.
For more information, see the QuickSpecs for the disk enclosure.
NOTE: Cabling illustrations are provided elsewhere in this guide, showing a variety of example
deployments. See (page 41).

NOTE: For the minimum supported configuration, and other configuration information, see the
QuickSpecs for the disk enclosure.
System and performance expectations
To help determine the best way to configure your storage, rank the following three storage
characteristics in order of importance:
•Fault tolerance (high availability)
•I/O performance
•Storage efficiency
With priorities established, you can determine which striping method and RAID level to use; some
configuration methods offer greater fault tolerance, while other configuration methods offer better
I/O performance or storage efficiency.
Striping methods
There are two methods for configuring the physical layout of the disk arrays:
•Vertical striping—the RAID array uses one physical drive from each disk enclosure.
•Horizontal striping—the RAID array uses multiple drives contained within one or more disk
enclosures.
RAID levels
Controllers use RAID technology to group multiple disk drives together in larger logical units (LUNs).
Key RAID methods include the use of data striping, data mirroring, and parity error checking. Data
striping improves speed by performing virtual disk I/O with an entire group of physical disks at
the same time. Mirroring provides data redundancy by storing data and a copy of the data. Parity
error checking provides automatic detection and correction if corruption of a physical disk occurs.
Depending on the host environment, the following RAID levels are supported with this disk enclosure:
RAID0, RAID1, RAID5 and RAID6 with ADG. Each level uses a different combination of RAID
methods that impact data redundancy, the amount of physical disk space used, and I/O speed.
After you create a LUN, you cannot change the RAID level.
The following table compares the different RAID levels.

Disk drive sizes and types
RAID arrays should be composed of disk drives of the same size and performance capability.
When drives are mixed within a disk enclosure, the usable capacity and the processing ability of
the entire storage subsystem is affected. For example, when a RAID array is composed of different
sized drives, the RAID array defaults to the smallest individual drive size, and capacity in the larger
drives goes unused.
Spare disks
Spares are disks that are not active members of any particular array, but have been configured
to be used when a disk in one of the arrays fails. If a spare is present, it will immediately be used
to begin rebuilding the information that was on the failed disk, using parity information from the
other member disks. During the rebuilding process, the array is operating in a reduced state and,
unless it is a RAID6 or RAID1+0 array, it cannot tolerate another disk failure in the same array. If
another disk fails at this time, the array becomes inaccessible and information stored there must
be restored from backup.
Preliminary tasks 23
After the rebuild of the data onto the spare is completed, when a replacement drive is inserted to
replace the failed drive, the system will automatically transfer the data from the spare onto the
replacement drive and return the spare to an available-spare state. It is important to note that the
process of rebuilding the spare or the replacement drive must not be interrupted or the process will
be aborted.
Some administrators have multiple spare disks, so that multiple arrays can experience failure and
successfully recover, before administrative intervention would be required to replace the spare or
failed disk. When assigning a spare to an array, the administrator chooses which arrays and how
many arrays are protected by that spare.
Array sizing
As a general rule, the greater the number of drives that are included in an array, the greater the
performance level that can be achieved. However, performance considerations are offset by fault
tolerance considerations. The greater the number of drives in an array, the higher the probability
of one or more disk failures in that array. The administrator must strike a balance between
performance and fault tolerance.
24 Installation
Preparing the site
Preparing your site includes:
•Providing adequate structural support
Calculate the total weight of your equipment and verify that your site can support the weight.
For HP ProLiant server environments, consider using Rack Builder, a software tool that provides
a simplified method to planning and configuring racks and rack-mountable products. Rack
Builder is available on the Options tab of the ProLiant Home page of the HP servers website:
http://www.hp.com/country/us/eng/prodserv/servers.html.
•Providing adequate clearance space and ventilation
Be sure to provide adequate clearance around the front and back of the racks. Provide at
least 63.5 cm (25 in) in the front of the rack to allow the doors to open fully and provide at
least 76.2 cm (30 in) in the rear of the rack to allow for servicing and airflow.
If there are unused spaces in your rack, attach blanking panels across those empty spaces to
force the airflow through the components instead of through the open spaces.
•Providing adequate and redundant sources of power
Make sure that you have two high-line power feeds installed near your computer. These two
power sources usually come from the same external power grid, but occasionally might
originate from different grids or even entirely different sources.
For protection against a power-source failure, obtain and include two uninterruptible power
supplies (UPS) in your installation. See the following URL for a list of available UPS:http://
www8.hp.com/us/en/products/ups/
For power consumption specifications, see the QuickSpecs for your disk enclosure model.
To ensure continuous, safe, and reliable operation of your equipment, place your system in an
approved environment.
Consider using the HP Enterprise Configurator (eCO) to help plan and configure racks and
rack-mountable devices. The eCO is available on the HP website: http://h30099.www3.hp.com/
configurator.
Preparing the site 25
Racking the disk enclosure
The disk enclosure can be installed into most standard server racks. To verify that your rack is
supported for use with the disk enclosure, see the QuickSpecs for the disk enclosure, available on
the D3000 website.
CAUTION: Install disk drives in the enclosures only after mounting the enclosures in the rack.
•A disk enclosure populated with disk drives is too heavy to lift safely.
•Movement of a disk enclosure during installation might damage the internal storage media
of installed disk drives.
Rack installation best practices
In addition to industry-standard recommendations, consider the following:
•Locate the heaviest items, such as uninterruptible power supplies (UPS) and additional disk
enclosures near the bottom of the rack.
•To make cabling easy, install the disk enclosures below the server.
•Install similar components next to each other in the rack. Because disk enclosures, switches,
and servers are of differing depths, if you have more than one of a device, mount those devices
adjacent to one another to accommodate working behind the rack.
WARNING! To reduce the risk of personal injury or damage to the equipment, be sure that:
•At least two people lift the storage system during removal or installation if the weight exceeds
22.7 kg (50 lb). If the system is being loaded into the rack above chest level, a third person
MUST assist with aligning the system with the rails while the other two people support the
weight of the system.
•The leveling jacks on the rack are extended to the floor.
•The full weight of the rack rests on the leveling jacks.
•The stabilizing feet are attached to the rack if it is a single-rack installation.
•The racks are coupled together in multiple-rack installations.
•Only one component in a rack is extended at a time. A rack might become unstable if more
than one component is extended.
•To prevent damage and to ease insertion of the device into the rack, support the weight of
the device and keep it level when sliding it into the rack.
Rack Installation procedures
1. Position left and right rack rails at the desired 'U' position in the rack, adjusting the rails to fit
the rack, as needed.
Front and Rear bottom edge of the rails must align with the bottom of EIA boundary in the
lowermost 'U'
NOTE: Rails are marked Land Rwith an arrow indicating the direction in which the rail
should be installed.
2. Use guide pins to align the shelf mount kit to the RETMA column holes.
The bottom of the rail must align with the bottom of the U.
3. To engage the rear, push the rail toward the back of the rack until the spring hook (1) snaps
into place.
26 Installation
4. To engage the front, pull the rail towards the front of the rack to engage the spring hook with
the RETMA column in the same manner as the rear spring hook.
NOTE: Make sure that the respective guide pins for the square or round hole rack align
properly into RETMA column hole spacing.
5. Secure rear of rack rail to the RETMA column with either the square- or round-hole shoulder
screws, provided in the plastic accessory bag.
6. Secure front of rail to the front RETMA column using the provided flat securing screw/guide
pin in the bottom screw position of the rail.
7. Slide the enclosure into position on the rails (1). Secure the chassis into the rack by tightening
the captive CTO screw behind the latch on the front left and right bezel ears of the chassis
(2).
CAUTION: The front CTO screw must be attached at all times when racked.
Racking the disk enclosure 27
8. The rear ends of the rails have a CTO bracket that must engage with the enclosure in order
to secure it to the rails.
Align the CTO bracket to the corresponding rear slot into the chassis. The movable bracket
can be slid forward or back to correct position. The provided screw will secure the bracket
and chassis to the rail.
NOTE: The provided screw must be secured tightly. HP recommends using a T25 driver.
9. When cabling the device, use holes provided in the rear rack rails, install tie wraps, and route
external cable(s) as required.
28 Installation
Installing disk drives in the enclosure
Disk drive options
Depending on the enclosure model, 12 or 25 disk drives can be installed in the enclosure.
A variety of disk drive models are supported for use, including dual-ported and single-ported
models. For more information about supported disk drives, see the QuickSpecs for the disk enclosure,
available on the D3000 website.
Disk drive guidelines
CAUTION:
•Follow industry-standard practices when handling disk drives. Internal storage media can be
damaged when drives are shaken, dropped, or roughly placed on a work surface.
•When installing a disk drive, press firmly to make sure the drive is fully seated in the drive
bay and then close the latch handle.
•When removing a disk drive, press the release button and pull the drive only slightly out of
the enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10
seconds before completely removing the drive from the enclosure.
•Always populate hard drive bays starting with the lowest bay number. If only one hard drive
is used, install it in the bay with the lowest device number.
•Disk drives are hot-pluggable.
•SAS and SATA disk drives may be installed in the same enclosure, but can not be included
in the same RAID logical volume.
Installing a disk drive
CAUTION: To prevent improper cooling and thermal damage, operate the enclosure only when
all bays are populated with either a component or a blank.
1. Remove the drive blank.
2. Unlatch and swing out the latch handle on the drive. Then, slide the drive into the bay (1),
pressing firmly on the drive to seat it. Close the latch handle (2), pressing firmly until it locks
in place.
Installing disk drives in the enclosure 29
IMPORTANT: When a drive is inserted in an operational enclosure, the drive LEDs flash to
indicate that the drive is seated properly and receiving power.
3. Determine the status of the hard drive.
IMPORTANT: For proper airflow and cooling, a drive blank must remain installed in all unused
drive bays.
30 Installation
Installing SAS controllers or controller enclosures
When installing controllers or controller enclosures, be sure to do the following.
•Record information about the controller or controller enclosure that will connect to the disk
enclosure.
•Depending on your deployment, do one of the following:
For server connect deployments, install one or more Smart Array controllers in the server
that will access the disk enclosure.
◦
◦For controller enclosure connect deployments, install or locate the controller enclosure to
which the disk enclosure will connect.
NOTE: For detailed installation and configuration information about controller cards or controller
enclosures, see the documentation provided with the controller card or controller enclosure.
Preparing the server
When preparing servers for the disk enclosure, be sure to do the following.
•Record information about the server and environment (server connect or controller enclosure
connect) that will connect to the disk enclosure.
•Verify that the servers, controllers, operating system version, and service packs are supported
for use with the disk enclosure. For more information, see the QuickSpecs for the disk enclosure,
available on the D3000 website.
•Install all operating-system-specific service packs, patch kits, or other required tools.
•Install HP system management and monitoring tools, such as HP Systems Insight Manager
(HP-SIM) and the Array Configuration Utility (ACU).
NOTE: For detailed installation and configuration information about the server or the software
tools, see the documentation provided with the server or software.
Installing SAS controllers or controller enclosures 31
Connecting SAS cables and power cords
Overview
Connecting cables includes the following steps:
1. Reading the “Cabling best practices” Page 32.
2. “Connecting SAS cables to the server or controller enclosure” Page 33.
3. “Connecting SAS cables to cascaded disk enclosures” Page 34.
4. “Connecting power cords” Page 35.
IMPORTANT: The following illustrations demonstrate connecting a disk enclosure to a server with
an installed controller. In your environment, the disk enclosure might connect to a controller
enclosure, which then connects to the host or network. Cabling restrictions may exist for the different
installation environments. For more information, see the user documents for your controller or
controller enclosure.
NOTE: For additional examples of cabling scenarios, see (page 41).
Cabling best practices
•Use supported SAS cables and power cords. A variety of cables and cable lengths are
supported for use with this disk enclosure. For more information, see the QuickSpecs for the
disk enclosure, available on the D3000 website.
•Use the shortest possible cable between devices. Shorter cables reduce the possibility of signal
degradation that might occur over longer distances. In addition, shorter cables are easier to
manage and route along the back of the rack.
•Gather cables in the rear of the disk enclosure to ensure that the cabling in the back of the
rack system does not interfere with system operation or maintenance. Bind cables loosely with
cable ties and route the cables out of the way, along the side of the rack. When the cables
are tied together and routed down the side of the rack, system components and indicators
are easily visible and accessible.
•Bind and support cables in a manner that eliminates stress on connectors and tight bends of
the cables. This prevents damage to the connector and cable, and ensures that the connector
remains fully seated in the port.
•Attach a label near both ends of each cable to identify the device connected to that cable.
Include the device, device name, port, or other useful information.
•Use colored markers to color code both ends of each cable, to help visually identify a particular
cable without having to read or locate the label.
•In multipath configurations, you might want to loosely bind the matching pair of cables
connecting devices.
32 Installation
Connecting SAS cables to the server or controller enclosure
To connect the first disk enclosure to the server or controller enclosure, use a standard mini-SAS
cable.
IMPORTANT: When connecting this disk enclosure in a single-domain environment, only the top
I/O module (I/O module A) in the disk enclosure is supported for use.
Observe the following guidelines:
•Only use supported SAS cables with mini-SAS connectors.
•Ensure that the servers or controller enclosures are powered down and power cords are
disconnected before connecting SAS cables to the disk enclosure.
The following illustration demonstrates connecting a disk enclosure to a server with an installed
controller. In your environment, the disk enclosure might connect to a controller enclosure, which
then connects to the host or network. Regardless of environment, cabling principles from the disk
enclosure to the host are the same.
Note the following when connecting cables:
•DP1 on the disk enclosure I/O module is treated as the SAS “in” port.
•DP2 on the disk enclosure I/O module is treated as the SAS “out” port.
•In single-domain configurations, one cable path is created between the host, the primary disk
enclosure, and additional cascaded disk enclosures. (Shown)
•In dual-domain configurations, two cable paths are created between the host, the primary
disk enclosure, and additional cascaded disk enclosures.
Connecting SAS cables and power cords 33
Connecting SAS cables to cascaded disk enclosures
To cascade additional disk enclosures from the disk enclosure that is connected to the server or
controller enclosure, use standard mini-SAS cables.
As additional disk enclosures are connected to the first disk enclosure, they are assigned a box
number. The assigned box number is displayed on the 7-segment display on the rear of the disk
enclosure.
IMPORTANT:
•When connecting this disk enclosure in a single-domain environment, only the top I/O module
(I/O module A) in the disk enclosure is supported for use.
•The number of supported cascaded disk enclosures varies per disk enclosure model and
installation environment. For more information, see the QuickSpecs for the disk enclosure,
controller, or controller enclosure, available on the HP storage website: http://www.hp.com/
go/storage.
Observe the following guidelines:
•Only use supported SAS cables with mini-SAS connectors.
•Use provided color clues on the disk enclosure when cabling cascaded disk enclosures; for
example, connect “green” ports to “green” ports (connect I/O module A on one disk enclosure
to I/O module A on the additional disk enclosure).
Note the following when connecting cables:
•DP1 on the disk enclosure I/O module is treated as the SAS “in” port.
•DP2 on the disk enclosure I/O module is treated as the SAS “out” port.
•In single-domain configurations, one cable path is created between the host, the primary disk
enclosure, and additional cascaded disk enclosures. (Shown)
•In dual-domain configurations, two cable paths are created between the host, the primary
disk enclosure, and additional cascaded disk enclosures.
34 Installation
Connecting power cords
When connecting power cords, use the cords shipped with the disk enclosure.
The power cord should be approved for use in your country. The power cord must be rated for the
product and for the voltage and current marked on the electrical ratings label of the product. The
voltage and current rating for the cord should be greater than the voltage and current rating marked
on the product. In addition, the diameter of the wire must be a minimum of 1.00 mm2or 18 AWG,
your maximum length may be up to 3.66 m (12 ft).
After power is supplied to the disk enclosure, the power supply automatically senses the input
voltage and the power supply LED illuminates as solid green.
To protect the system from power-failure-related downtime, each disk enclosure ships standard with
a redundant power supply. Depending how you connect the power supplies to the power source,
you can eliminate downtime caused by power-related failures.
Level of ProtectionConnection Method

46 Troubleshooting
Recognizing disk drive failure
In an HP enclosure, a steadily glowing fault LED indicates that a disk drive has failed. Other
indications of failed disk drives are as follows:
•ACU represents failed drives with a distinctive icon.
•HP SIM can detect failed drives remotely across a network. (For more information about HP
SIM, see the documentation on the Management CD.)
•ADU lists all failed drives.
•Operating System log files
For additional information about diagnosing disk drive problems, see the HP ProLiant Servers
Troubleshooting Guide.
Effects of a disk drive failure
When a disk drive fails, all logical drives that are in the same array are affected. Each logical
drive in an array might be using a different fault-tolerance method, so each logical drive can be
affected differently.
•RAID0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all
non-fault-tolerant (RAID0) logical drives in the same array also fail.
•RAID1+0 configurations can tolerate multiple drive failures as long as no failed drives are
mirrored to one another (with no spares assigned).
•RAID5 configurations can tolerate one drive failure (with no spares assigned).
•RAID6 with ADG configurations can tolerate simultaneous failure of two drives (with no spares
assigned).
Compromised fault tolerance
If more disk drives fail than the fault-tolerance method allows, fault tolerance is compromised, and
the logical drive fails.
Factors to consider before replacing disk drives
Before replacing a degraded drive:
•Open HP SIM and inspect the Error Counter window for each physical drive in the same array
to confirm that no other drives have any errors. For details, see the HP SIM documentation on
the Management CD.
•Be sure that the array has a current, valid backup.
•Use replacement drives that have a capacity at least as great as that of the smallest drive in
the array. The controller immediately fails drives that have insufficient capacity.
Recognizing disk drive failure 47
To minimize the likelihood of fatal system errors, take these precautions when removing failed
drives:
•Do not remove a degraded drive if any other drive in the array is offline (the online LED is
off). In this situation, no other drive in the array can be removed without data loss.
•Exceptions:
When RAID1+0 is used, drives are mirrored in pairs. Several drives can be in a failed
condition simultaneously (and they can all be replaced simultaneously) without data loss,
as long as no two failed drives belong to the same mirrored pair.
◦
◦When RAID6 with ADG is used, two drives can fail simultaneously (and be replaced
simultaneously) without data loss.
◦If the offline drive is a spare, the degraded drive can be replaced.
•Do not remove a second drive from an array until the first failed or missing drive has been
replaced and the rebuild process is complete. (The rebuild is complete when the Online LED
on the front of the drive stops blinking.)
Exceptions:
◦In RAID6 with ADG configurations, any two drives in the array can be replaced
simultaneously.
◦In RAID1+0 configurations, any drives that are not mirrored to other removed or failed
drives can be simultaneously replaced offline without data loss.
Automatic data recovery (rebuild)
When you replace a disk drive in an array, the controller uses the fault-tolerance information on
the remaining drives in the array to reconstruct the missing data (the data that was originally on
the replaced drive) and write it to the replacement drive. This process is called automatic data
recovery, or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is
likely to be permanently lost.
Time required for a rebuild
•The time required for a rebuild varies considerably, depending on several factors:
•The priority that the rebuild is given over normal I/O operations (you can change the priority
setting by using ACU)
•The amount of I/O activity during the rebuild operation
•The rotational speed of the disk drives
•The availability of drive cache
•The model and age of the drives
•The amount of unused capacity on the drives
•The number of drives in the array (for RAID5 and RAID6 with ADG)
Allow approximately 5 minutes per gigabyte without any I/O activity during the rebuild process.
This figure is conservative, and newer drive models usually require less time to rebuild.
System performance is affected during the rebuild, and the system is unprotected against further
drive failure until the rebuild has finished. Therefore, replace drives during periods of low activity
when possible.
CAUTION: If the Online LED of the replacement drive stops blinking and the amber fault LED
glows, or if other drive LEDs in the array go out, the replacement drive has failed and is producing
unrecoverable disk errors. Remove and replace the failed replacement drive.
48 Troubleshooting
When automatic data recovery has finished, the online LED of the replacement drive stops blinking
and begins to glow steadily.
Failure of another drive during rebuild
If a non-correctable read error occurs on another physical drive in the array during the rebuild
process, the Online LED of the replacement drive stops blinking and the rebuild abnormally
terminates. If this situation occurs, restart the server. The system might temporarily become
operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive,
replace it, and restore data from backup.
Handling disk drive failures
If the controller was configured with hardware fault tolerance, complete the following steps after
a disk drive failure:
1. Determine which physical drive failed. On hot-plug drives, an amber drive failure LED
illuminates.
2. If the unit containing the failed drive does not support hot-plug drives, perform a normal
shutdown.
3. Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug
drives, after you secure the drive in the bay, the LEDs on the drive each flash once in an
alternating pattern to indicate a successful connection. The online LED flashes, indicating that
the controller recognized the drive replacement and began the recovery process.
4. Power on the server, if applicable.
5. The controller reconstructs the information on the new drive, based on information from the
remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives,
the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.

9 Replacement procedures
Customer self repair (CSR)
Information in (page 52) identifies hardware components that are customer replaceable. Using
WEBES, ISEE or other diagnostic tools, a support specialist will work with you to diagnose and
assess whether a replacement component is required to address a system problem. The specialist
will also help you determine whether you can perform the replacement.
Parts-only warranty service
Your HP Limited Warranty might include a parts-only warranty service. Under the terms of parts-only
warranty service, HP will provide replacement parts free of charge.
For parts-only warranty service, CSR part replacement is mandatory. If you request HP to replace
these parts, you will be charged for travel and labor costs.
Best practices for replacing hardware components
The following information will help you replace the hardware components on your storage system
successfully.
CAUTION: Removing a component significantly changes the air flow within the enclosure.
Components or a blanking panel must be installed for the enclosure to cool properly. If a component
fails, leave it in place in the enclosure until a new component is available to install.
Verifying component failure
•Consult HP technical support to verify that the hardware component has failed and that you
are authorized to replace it yourself.
•Additional hardware failures can complicate component replacement. Check your management
utilities to detect any additional hardware problems:
◦When you have confirmed that a component replacement is required, you might want to
clear the failure message from the display. This makes it easier to identify additional
hardware problems that might occur while waiting for the replacement part.
◦Before installing the replacement part, check the management utility for new hardware
problems. If additional hardware problems have occurred, contact HP support before
replacing the component.
Identifying the spare part
Parts have a nine-character spare part number on their label. For some spare parts, the part number
might be available in the management software utility. Alternatively, the HP call center will assist
in identifying the correct spare part number.
Replaceable parts
This product contains the replaceable parts illustrated in (page 52).

Replacing the failed component
CAUTION: Components can be damaged by electrostatic discharge (ESD). Use proper anti-static
protection.
•Always transport and store components in an ESD protective enclosure.
•Do not remove the components from the ESD protective enclosure until you are ready to install
it.
•Always use ESD precautions, such as a wrist strap, heel straps on conductive flooring, and
an ESD protective smock when handling ESD sensitive equipment.
•Avoid touching the components connector pins, leads, or circuitry.
•Do not place ESD generating material such as paper or non anti-static (pink) plastic in an ESD
protective enclosure with ESD sensitive equipment.
•HP recommends waiting until periods of low storage system activity to replace a component.
•When replacing components at the rear of the rack, cabling might obstruct access to the
component. Carefully move any cables out of the way to avoid loosening any connections.
In particular, avoid cable damage that might be caused by:
◦Kinking or bending.
◦Disconnecting cables without capping. If uncapped, cable performance might be impaired
by contact with dust, metal or other surfaces.
◦Placing removed cables on the floor or other surfaces, where they might be walked on
or otherwise compressed.
