7-segment display

The 7-segment display shows the box ID number assigned to the enclosure based on how it is connected to the controller. If there are multiple enclosures attached to the controller, the box ID number identifies the order in which they are attached.

NOTE:

Depending on your environment, you can also view device information through management software utilities, such as the HP System Management Home page, HP Systems Insight Manager (HP SIM), Storage Management Utility (SMU), or Command Line Interface (CLI).

Hardware features and LED descriptions10

2 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.

70 Modular Smart Array User Guide 11

Deployment types12

3 Installing the enclosure

Environmental requirements

When installing the enclosure in a rack, select a location that meets the environmental standards described in this section.

Space and airflow requirements

To allow for servicing and adequate airflow, observe the following space and airflow requirements when deciding where to install a rack:

• Leave minimum clearance of 63.5 cm (25 in) in front of the rack.

• Leave minimum clearance of 76.2 cm (30 in) behind the rack.

• Leave minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another

rack or row of racks.

HP enclosures draw in cool air through the front door and expel warm air through the rear door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.

CAUTION:

To prevent improper cooling and damage to the equipment, do not block the ventilation openings.

CAUTION:

When a vertical space in the rack is not filled by a server or rack component, the gaps between the components cause changes in airflow through the rack and across the servers. Always use blanking panels to fill empty vertical spaces in the rack. This arrangement ensures proper airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal damage.

The 9000 and 10000 Series racks provide proper server cooling from flow-through perforations in the front and rear doors that provide 64 percent open area for ventilation.

CAUTION:

When using a Compaq-branded 7000 Series rack, you must install the high airflow rack door insert [P/N 327281-B21 (42U) or P/N 157847-B21 (22U)] to provide proper front-to-back airflow and cooling.

70 Modular Smart Array User Guide 13

CAUTION:

If a third-party rack is used, observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment:

• Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350

sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation).

• Side—The clearance between the installed rack component and the side panels of the rack must

be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the enclosure in a well-ventilated, climate-controlled environment.

The maximum recommended ambient operating temperature (TMRA) for most enclosure products is 35°C (95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).

CAUTION:

To reduce the risk of damage to the equipment when installing third-party options:

• Do not permit optional equipment to impede airflow around the enclosure or to increase the in-

ternal rack temperature beyond the maximum allowable limits.

• Do not exceed the manufacturer’s TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing the installation of IT equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, see the product rating label or the user documentation supplied with that option.

WARNING!

To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over wiring and installation requirements of your facility.

CAUTION:

Protect the enclosure from power fluctuations and temporary interruptions with a regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes and keeps the enclosure in operation during a power failure.

When installing more than one enclosure, you may need to use additional power distribution devices to safely provide power to all devices. Observe the following guidelines:

Installing the enclosure14

• Balance the enclosure power load between available AC supply branch circuits.

• Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC

current rating.

• Do not use common power outlet strips for this equipment.

• Provide a separate electrical circuit for each power supply in the enclosure.

Electrical grounding requirements

The enclosure must be grounded properly for proper operation and safety. In the United States, you must install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any local and regional building codes. In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through

7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices.

Because of the high ground-leakage currents associated with multiple enclosures connected to the same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently wired to the building’s branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for the enclosure is not recommended.

Rack planning resources

The rack resource kit ships with all HP-branded or Compaq-branded 9000, 10000, and H9 Series racks. For more information on the content of each resource, see the rack resource kit documentation.

If you intend to deploy and configure multiple servers in a single rack, see the white paper on high-density deployment at the HP website: http://www.hp.com/products/servers/platforms.

Rack warnings

WARNING!

To reduce the risk of personal injury or damage to the equipment, be sure that:

• The leveling jacks 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 is extended at a time. A rack may become unstable if more than one com-

ponent is extended for any reason.

70 Modular Smart Array User Guide 15

WARNING!

To reduce the risk of personal injury or equipment damage when unloading a rack:

• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can

weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become unstable when being moved on its casters.

• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle

the rack from both sides.

Installing disk drives

Disk drive options

The enclosure supports up to 25 SAS or SATA disk drives.

A variety of disk drive models are supported for use, including dual-ported and single-ported disk drives. For more information about supported disk drives, see the QuickSpecs for the disk enclosure, available on the MSA70 website.

Disk drive guidelines

When adding disk drives to the enclosure, observe the following general guidelines:

70 Modular Smart Array User Guide 19

• 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.

• The system automatically sets all device numbers.

• Always populate disk drive bays starting with the lowest bay number. If only one disk drive is

used, install it in the bay with the lowest device number.

• Drives must be the same capacity to provide the greatest storage space efficiency when drives

are grouped together into the same drive array.

• 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.

Installing the enclosure20

2. Press the latch and slide it to the right to disengage the lever (1), and then open the lever (2).

Make sure that the lever is in the fully opened position before inserting the drive into the bay.

3. Slide the disk drive into the bay (1), pressing firmly on the drive to seat it. Close the lever (2),

pressing firmly until it locks in place

IMPORTANT:

When the drive is inserted in an operational enclosure, the drive LEDs flash for 2 seconds to indicate that the drive is seated properly and receiving power.

4. Determine the status of the disk drive (see Hard drive LED combinations).

IMPORTANT:

For proper airflow and cooling, a blank must remain installed in all unused drive bays.

70 Modular Smart Array User Guide 21

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.

• Verify that the controller or controller enclosure is supported for use with the disk enclosure. For

more information, see the QuickSpecs for the disk enclosure.

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 server, operating system version, and service packs are supported for use with the

disk enclosure. For more information, see the QuickSpecs for the disk enclosure.

• 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 the enclosure22

Connecting SAS cables and power cords

After installing the enclosure in a rack, connect the SAS cables and power cords.

Cabling best practices

• Use the shortest possible cable between devices. Shorter cables are easier to manage and route

along the back of the rack. In addition, shorter cables reduce the possibility of signal degradation that might occur over longer distances.

• Gather the 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 the cables loosely with cable ties and route the excess 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.

• 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.

Connecting SAS cables to the server or controller enclosure

To connect the first disk enclosure to the server or controller enclosure, use a supported SAS cable.

NOTE:

The left connector on the I/O module is for input from the server or controller enclosure. The right connector on the I/O module is for output to an additional enclosure. See the icons on the cables and the enclosure to assist in proper connection.

Observe the following guidelines for SAS cabling:

• Only use supported SAS cables with 3-GB connectors.

• Ensure that the servers or controller enclosures attached to the disk enclosure are powered down

and power cords are disconnected before connecting SAS cables.

• A 0.5-m (1.64-ft) SAS cable ships standard with the enclosure. HP recommends using the shortest

cable possible, however, other supported cable lengths between SAS ports are 2 m (6.56 ft), 4 m (13.12 ft), and 6 m (19.69 ft). To acquire different lengths, contact the nearest authorized HP reseller.

70 Modular Smart Array User Guide 23

Connecting SAS cables to additional disk enclosures

To connect an additional disk enclosure to a disk enclosure that is already connected to the server or controller enclosure, use a supported SAS cable.

NOTE:

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:

• 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 and the controller or controller enclosure, available on the HP storage website: http://www.hp.com/go/storage.

• When connecting this disk enclosure in a single-domain environment, only one I/O module in

the disk enclosure is supported for use.

• 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).

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 amber.

WARNING!

To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.

• Unplug the power cord from the power supply to disconnect power to the equipment.

• Do not route the power cord where it can be walked on or pinched by items placed against it.

Pay particular attention to the plug, electrical outlet, and the point where the cord extends from the storage system.

Installing the enclosure24

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.

70 Modular Smart Array User Guide 25

Powering on the disk enclosure

After disk enclosures are physically installed and cabled, power on all devices and verify that they are operating properly.

Power on best practices

Observe the following best practices before powering on the disk enclosure for the first time:

• Complete the server, controller, or controller enclosure installation. For more information, see the

server, controller, or controller enclosure user documents.

• Install the disk enclosures.

• Install disk drives in the disk enclosures so that the connected host controller can identify and

configure them at power on.

• Connect the SAS cables and power cords to the enclosure.

Powering on disk enclosures

IMPORTANT:

Always power on disk enclosures before controller enclosures and servers. This ensures that servers, during the discovery process, identify the enclosures and installed disk drives as operational devices.

1. Apply power to each uninterruptible power supply (UPS). For more information, see the UPS

documentation.

2. Apply power to the disk enclosures. Press and hold the power on/standby button on the disk

enclosures until the system power LED illuminates solid green. The LED on the power on/standby button changes from amber to solid green, indicating that the

disk enclosure has transitioned from a standby state to fully powered.

3. Wait a few minutes for the disk enclosures to complete their startup routines.

IMPORTANT:

4 Configuring the enclosure

Configuration overview

Regardless of the operating system environment or software tool used to configure the disk enclosure, the following tasks must be completed:

• Updating controller or controller enclosure firmware or drivers. Instructions are included with the

controller or controller enclosure.

• Updating disk enclosure firmware. Instructions are included with the firmware. For more information,

see “Updating disk enclosure firmware” on page 32.

• Configuring the disk enclosure and its storage.

• Creating the logical storage units (LUNs).

• Entering global controller settings, such as setting the read/write cache ratio, setting the re-

build/expand priority, and setting the redundancy level.

• Identifying the operating system type (also called Host Mode or Profile) of the host that will

access the disk enclosure. This ensures that the disk enclosure will communicate properly with that host.

• Verifying that the configured storage is visible to the host.

Supported software tools

A variety of configuration, management, and diagnostic tools are supported for use with these disk enclosures. Which tools are supported for your installation environment is determined by the server and controller or controller enclosure to which the disk enclosure is connected.

6 Troubleshooting

When the enclosure does not start

If the enclosure does not power up:

1. Verify that the server, monitor, and enclosure are plugged in.

2. Verify that the server and monitor are working.

3. Verify that the power source is working:

a. Ensure that the Power On/Standby button was pressed firmly and held for approximately

three seconds.

b. View the system power LED on the back panel (see Rear panel LEDs and buttons).

4. Verify that the power supplies are working properly by viewing the power supply LEDs on the

back panel (see Rear panel LEDs and buttons).

5. Disconnect the AC power cords from both enclosure power supplies and reconnect them.

6. Restart the enclosure.

IMPORTANT:

If the system does not restart, proceed to Diagnostic steps.

7. Check the enclosure for the following normal power-up sequence to be sure that the system meets

the minimal hardware requirements and is powered up during normal operations:

a. The front panel power LED turns from standby/off (amber) to on (solid green). b. The fans spin up to a high speed, and then spin down to a normal operating speed.

Recognizing disk drive failure

In an HP enclosure, a steadily glowing fault LED indicates that a 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.

Troubleshooting34

• CPQONLIN identifies failed drives in a NetWare environment.

For additional information about diagnosing disk drive problems, see the HP ProLiant Servers Troubleshooting Guide.

CAUTION:

Sometimes, a drive that has previously failed may seem to be operational after the system is power-cycled or, for a hot-pluggable drive, after the drive has been removed and reinserted. However, continued use of such marginal drives may eventually result in data loss. Replace the marginal drive as soon as possible.

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 may be using a different fault-tolerance method, so each logical drive can be affected differently.

• RAID 0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all non-

fault-tolerant (RAID 0) logical drives in the same array also fail.

• RAID 1+0 configurations can tolerate multiple drive failures as long as no failed drives are mirrored

to one another (with no spares assigned).

• RAID 5 configurations can tolerate one drive failure (with no spares assigned).

• RAID 6 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. In this case, all requests from the operating system are rejected with unrecoverable errors. You are likely to lose data, although it can sometimes be recovered.

One example of a situation in which compromised fault tolerance may occur is when a drive in an array fails while another drive in the array is being rebuilt. If the array has no online spare, any logical drives in this array that are configured with RAID 5 fault tolerance will fail.

Compromised fault tolerance can also be caused by non-drive problems, such as a faulty cable or temporary power loss to a storage system. In such cases, you do not need to replace the physical drives. However, you may still have lost data, especially if the system was busy at the time that the problem occurred.

Recovering from compromised fault tolerance

If fault tolerance is compromised, inserting replacement drives does not improve the condition of the logical volume. Perform the following procedure to recover data:

1. Power down the enclosure (see Powering off disk enclosures).

2. Check for loose, dirty, broken, or bent cabling and connectors on all devices.

70 Modular Smart Array User Guide 35

3. Power up the enclosure (see Powering on disk enclosures).

NOTE:

In some cases, a marginal drive is operational long enough to allow backups of important files.

4. Make copies of important data, if possible.

5. Replace any failed drives. Read Factors to consider before replacing hard drives before replacing

the failed disk drives.

Factors to consider before replacing disk drives

In systems that use external data storage, be sure that the server is the first unit to be powered down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up.

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.

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 RAID 1+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 RAID 6 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 RAID 6 with ADG configurations, any two drives in the array can be replaced simultaneously.

• In RAID 1+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,

Troubleshooting36

or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is likely to be permanently lost.

If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error may occur, and all data on the array is then lost. In exceptional cases, however, failure of another drive need not lead to a fatal system error. These exceptions include:

• Failure after activation of a spare drive.

• Failure of a drive that is not mirrored to any other failed drives (in a RAID 1+0 configuration).

• Failure of a second drive in a RAID 6 with ADG configuration.

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 brand, model, and age of the drives

• The amount of unused capacity on the drives

• The number of drives in the array (for RAID 5 and RAID 6 with ADG)

Allow approximately 15 minutes per gigabyte for the rebuild process to be completed. 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.

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 may 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.

Drive failure in a NetWare environment

Use CPQONLIN to identify and monitor drive failure status in a NetWare environment.

70 Modular Smart Array User Guide 37

Failed drives or interim recovery mode

If a drive fails and hardware fault tolerance is enabled, operation continues. Do the following:

1. Replace the drive as soon as possible.

2. Select a logical drive.

3. Press the F3 key to monitor to the status of drive recovery.

Drive status messages include:

• Interim Recovery: The logical drive is operating, but a failed drive has not been replaced.

Replace the drive as soon as possible.

• Ready for Recovery: The logical drives are queued for recovery. This status is displayed when

another logical drive is already rebuilding or expanding.

• Rebuilding: The array is operating and rebuilding a replacement drive or an online spare, if

one was assigned.

• Logical Drive Failed: If you have one or more logical drives that are not protected by fault

tolerance in an array, the data on these logical drives will be lost. ACU shows the logical drives as FAILED. After drive replacement, any fault-tolerant logical drives rebuild. The logical drives that were not protected (FAILED) become available for data (the devices are reactivated automatically). If you have a backup of the data, restore the data now.

If you do not replace the failed drive, the only option, using ACU, is to delete logical drives. Do not delete logical drives that contain valid data. Doing so results in data loss.

NOTE:

A failed status can occur on drives protected by fault tolerance if two or more physical drives fail concurrently.

Some status messages are available without pressing the F3 key. For example, on the Main menu, the FAILED status appears next to the logical drive that has failed. EXPANDING and REBUILDING appear next to the array in which the activity is occurring.

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 up 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.

Troubleshooting38

NOTE:

NetWare cannot detect a single physical drive failure when using hardware-based fault tolerance. NetWare determines that the data is still valid and accessible during the rebuilding process. However, the driver knows that a physical drive has failed. A message is printed on the console notifying the user that a physical drive is in a degraded state. CPQONLIN also shows that the drive has failed.

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.

Wrist straps are flexible straps with a minimum of 1 megohm. ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against

the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet

when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.
