Power supply/fan assembly LEDs
Each power supply/fan assembly has one LED.
The LED is illuminated when both the power supply and the fan are operational. When a power supply or fan fault occurs, the LED goes off. If the LED is off, AC power is not present or there is a complete power supply failure.
15583
The power-supply-mounted fans cool the chassis by circulating air through the enclosure. The rate at which air moves (the airflow) determines the amount of cooling. This airflow is a function of fan speed
(rpm). These fans, under the control of the Environmental Monitoring Unit (EMU) or the associated power supply, can operate at multiple speeds. This ensures that when the enclosure temperature changes, the fans can automatically adjust the airflow. If one fan operates too slowly or completely shuts off, the other fan operates at a higher speed. At the same time, the error condition is reported to the user via the LCD panel on the front of the controller.

System Event Analyzer (SEA) overview
System Event Analyzer is a host-based fault analysis utility included with the Web-Based Service Enterprise
(WEBES) service tools. Each WEBES service tool adds functionality to the Directory, a process (or set of processes) that executes continuously. SEA provides the Director with the capability of capturing and interpreting hardware events. The analysis of events can be performed automatically or when requested by an outside process.
SEA provides background automatic analysis by monitoring the active binary event log (also called the system event log or error log) and processing events as they occur. The events in the binary event log file are checked against the analysis rules. If one or more of the events in the binary event log file meets the conditions specified in the rules, the analysis engine collects the error data and creates a problem report containing a description of the problem and any corrective actions required. After the problem report is created, it is distributed in accordance with the customer’s notification preferences.
SEA features:
• Error event analysis and translation
• Multi-event correlation (view events, traps, etc.) maintenance and service guide 31
• Manual and automatic (real-time) analysis capabilities on local or remote machines
• Filtering capabilities on error logs
• Automatic notification (customer or HP Support Center)
• Rule-based (allowing more frequent updates)
• Proactive indictment with the operating system
• Web and command line interfaces

Some messages may specify a box number. For the MSA1000, the following box numbers are defined:
Pre-defined box number Physical connection to MSA SCSI I/O module
Box 1 This is the MSA1000 chassis
Box 2 Port A of the SCSI I/O module
Box 3 Port B of the SCSI I/O module
LCD panel overview
Each array controller contains an integrated Liquid Crystal Display (LCD). This module is used for displaying informational and error messages, showing the status of the module, and for providing user input when required.
Traditional Power-On Self-Test (POST) messages issued by the PCI-based controllers have been combined with runtime event notification messages to create a new set of controller display messages. The display module is capable of holding up to 100 messages. After this maximum size is reached, older messages are removed to make room for newer ones. When a new message is sent to the LCD, the display shows that message and ignores any previous scrolling position. This new message is now the most recent message available.
To use the input buttons on the LCD panel:
• Press the Up navigation button to view older messages.
• Press the Down navigation button to view more recent messages.
• Press the Left navigation button to jump to the last message.
• Press the Right navigation button to enter the Management menu.
• Press the Left and Right navigation buttons at the same time to delete the currently displayed message.
The display module consists of the following components: maintenance and service guide 33

LCD message types
The display module is capable of holding up to 100 messages. Once this maximum has been reached, older messages are removed to make room for newer ones. Messages can be of three types:
For a complete list of messages and their meanings, see
Error messages
Error messages indicate that a problem has occurred and may require user action to correct it.
The array controller Fault LED to the left of the LCD display panel lights whenever a new error message is sent to the display panel and has not been viewed, and when an error message is currently displayed for viewing. After all error messages have been viewed, the LED turns off and is re-lit only when an error message is currently being viewed or a new error message is sent to the display panel.
Informational messages
Informational messages indicate non-critical changes in the system that are provided as feedback to the user.
The array controller Fault LED to the left of the LCD display is off when an informational message is currently being viewed, unless an unviewed error message was previously sent to the display module.
After all error messages have been viewed, the LED returns to lighting up only when currently on an error message.
34 LCD panel and message descriptions
User input messages
User input messages indicate that the system has encountered a situation that allows user input. The user can select from a number of choices. If the user does not select one of the choices in a set amount of time, the system selects the default setting. These user input messages only occur during system power on, and not during runtime.
The array controller Fault LED to the left of the LCD panel display window blinks on and off when a user input message is currently being viewed and is available for input. If input is not provided within the time-out period, the message remains but the LED stops blinking.

If <n> = 2.3: The single cache module on this array controller was replaced, but with cache module containing data from a different array controller.
Return the cache module to its original array controller, power on the system without allowing any host I/O, and wait for cache data to be written to hard drives. The system can be powered off and the cache module moved to the new location.
< = no. The array controller will halt.

For the MSA1500, before using an attached MSA20, the MSA20 is checked to see if any hard drives contain configuration data from a source other than the MSA1500. If so, the enclosure is failed and this message is displayed.
An MSA20 attached to an MSA1500 must be configured by the 1500.
Attaching an MSA20 that was configured by a Smart
Array Controller is not supported and will result in data loss of that existing
MSA20 configuration.
The configured volume has returned to its normal operating state. This typically occurs after a rebuild operation has completed.
The configured volume has been failed because too many SCSI hard drives that it is composed of have failed, exceeding the fault tolerance level. The data on the configured volume is no longer available. There is a risk of data loss.
The array controller has failed one or more
SCSI hard drives that the configured volume is composed of, but no data loss has occurred because fault tolerance is allowing the data to be recovered.
The configured volume is rebuilding data on a SCSI hard drive that replaced a previously failed drive.

The configured volume is waiting to start a volume expansion operation.
The expansion may have not started yet because another configured volume is undergoing expansion or a rebuild is occurring on the configured volume.
The configured volume is missing too many of the
SCSI hard drives that it is composed of, making it unusable. The volume is disabled.
Action
The configured volume appears to have had known, good SCSI hard drives replaced instead of known, failed hard drives.
The volume expansion operation on the configured volume has been disabled.
This may be because a rebuild operation is ongoing, another expansion is already running, or the cache memory is disabled due to a low battery. The expansion will start once the condition has been cleared.
The array controller is calculating and storing parity information for the configured volume and therefore performance may be lower until it completes.
Power off the MSA and then all attached storage enclosures. Unplug and reinsert all SCSI hard drives ensuring they are fully seated in their bays. Check the cables connecting the MSA to any attached storage enclosures. Power on the attached enclosures and then the MSA.

Customer self repair
HP products are designed with many Customer Self Repair (CSR) components to minimize repair time and allow for greater flexibility in performing defective parts replacement. If, during the diagnosis period, HP
(or HP service providers or partners) identifies that the repair can be accomplished by the use of a CSR port, HP will ship that part directly to you for replacement. There are two categories of CSR parts:
• Mandatory — parts for which customer self repair is mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs of this service.
• Optional — Parts for which customer self repair is optional. These parts are also designed for customer self repair. If, however, you require that HP replace them for you, there may or may not be additional charges, depending on the type of warranty service designated for your product.
NOTE:
Some HP parts are not designed for customer self repair. To satisfy the customer warranty, HP requires that an authorized service provider replace the part. These parts are identified as
No
in the
.
Based on availability and where geography permits, CSR parts will be shipped for next business day delivery. Same day or four-hour delivery may be offered at an additional charge where geography permits. If assistance is required, you can call the HP Technical Support Center and a technician will help you over the telephone. HP specifies in the materials shipped with a replacement CSR part whether a defective part must be returned to HP. In cases where it is required to return the defective part to HP, you must ship the defective part back to HP within a defined period of time, normally five (5) business days.
The defective part must be returned with the associated documentation in the provided shipping material.
Failure to return the defective part may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to be used.

Warnings and precautions
• Electrostatic Discharge Information
• Rack warnings and precautions
• Device warnings and precautions
Electrostatic discharge information
To prevent damage to 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, observe the following precautions:
• Avoid hand contact by transporting products in static-safe containers such as conductive tubes, bags, or boxes.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
• Cover workstations with approved static-dissipating material. Provide a wrist strap connected to the work surface and properly grounded (earthed) tools and equipment.
• Keep work area free of nonconducting materials such as ordinary plastic assembly aids and foam packing.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Make sure that you are properly grounded when touching a static-sensitive component or assembly.
• Place hard drives with the Printed Circuit Board (PCB) side down.
• Use conductive field service tools.
Grounding methods
There are several methods 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% 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 HP
Reseller install the part.
NOTE:
For more information on static electricity or assistance with product installation, contact your HP
Authorized Reseller.

Weight warning
WARNING!
The device can be very heavy. To reduce the risk of personal injury or damage to equipment:
• Remove all hot-pluggable power supplies and modules to reduce the overall weight of the device before lifting.
• Observe local health and safety requirements and guidelines for manual material handling.
• Get help to lift and stabilize the device during installation or removal, especially when the device is not fastened to the rails. When a device weighs more than 22.5 kg (50 lb), at least two people must lift the component into the rack together. If the component is loaded into the rack above chest level, a third person must assist in aligning the rails while the other two support the device.
Rack warnings and precautions
Ensure that precautions have been taken to provide for rack stability and safety. It is important to follow these precautions providing for rack stability and safety, and to protect both personnel and property.
Heed all cautions and warnings included in the installation instructions.
WARNING!
To reduce the risk of personal injury or damage to the equipment:
• Observe local occupational safety requirements and guidelines for heavy equipment handling.
• Obtain adequate assistance to lift and stabilize the product during installation or removal.
• Remove all pluggable power supplies and modules to reduce the weight of the product.
• Load the heaviest item first, and load the rack from the bottom up. This makes the rack
“bottom-heavy” and helps prevent the rack from becoming unstable.
• Extend the leveling jacks to the floor.
• Rest the full weight of the rack on the leveling jacks.
• Attach stabilizing feet to the rack if it is a single-rack installation.
• Ensure the racks are coupled in multiple-rack installations.
• Fully extend the bottom stabilizers on the equipment. Ensure that the equipment is properly supported/braced when installing options and boards.
• Be careful when sliding rack components with slide rails into the rack. The slide rails could pinch your fingertips.
• Ensure that the rack is adequately stabilized before extending a rack component with slide rails outside the rack. Extend only one component at a time. A rack may become unstable if more than one component is extended for any reason.
• Do not attempt to move a fully loaded equipment rack. Remove equipment from the rack before moving the rack.
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs
115 kilograms (253 pounds), is over 2.1 meters (7 feet) tall, and can become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet; handle it from the sides. Stabilize the device by keeping the unit on the rails.
64 Customer replaceable components
WARNING!
Verify that the AC power supply branch circuit that provides power to the rack is not overloaded.
Overloading AC power to the rack power supply circuit increases the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating.
Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.

Uninterruptible Power Supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes, and keeps the system in operation during a power failure.
maintenance and service guide 65
CAUTION:
To properly ventilate the system, you must provide at least 7.6 centimeters (3.0 inches) of clearance at the front and back of the device.
CAUTION:
When removing or replacing a failed component, allow 30 seconds to pass before inserting a replacement component. This time is needed to allow the device to clear out the system registries.
CAUTION:
Schedule physical configuration changes during periods of low or no activity. If the system is performing rebuilds, RAID migrations, array expansions LUN expansions, or experiencing heavy I/O, avoid physical configuration changes such as adding or replacing hard drives or hot-plugging a controller or any other component. For example, hot-adding or replacing a controller while under heavy I/O may cause a momentary pause, performance decrease, or lass of access to the MSA while the new controller is starting up. When the controller completes the startup process, full functionality is restored.
CAUTION:
Before replacing a hot-pluggable component, ensure that steps have been taken to prevent loss of data.

Connecting power to the MSA
HP strongly recommends using the power cord shipped with the MSA. If using a different power cord, your 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 of 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 1.02 mm² or 18 AWG. If you are using 18 AWG, your maximum length may be up to 3.65 meters (12 feet).
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the cord exits from the product.
After all hardware components are installed and the unit is in place, the power can be connected.
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord's 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.
1.
Plug one end of the AC power cord into a power supply on the rear of the MSA. The power supply automatically senses the input voltage. It is not necessary to select the correct main voltage.
2.
Plug the other end of the AC power cord into a nearby, grounded outlet.
3.
Plug the second AC power cord into the redundant power supply.
4.
Plug the second AC power cord into a grounded outlet nearby.

Applying power to the MSA
Before applying power to the MSA, all components of the storage system must be installed and connected to the supported interconnect options. Hard drives should be installed in the enclosures so that they can be identified and configured at power up.
The MSA and the other network components must be powered on in the following sequence:
1.
Verify that the following devices are powered on and in a ready state:
• Uninterruptible Power Supplies (UPS)
• External storage enclosures
• Network switches
NOTE:
Proceed to the next step only after these devices, especially the external storage enclosures have completed their startup routines. If the MSA is powered on before the external enclosures complete their startup sequence, the MSA may not properly discover the storage.
Any configured arrays may be marked as failed and will have to manually be re-enabled.
2.
Start up the MSA by pressing the Power/Standby button on the front of the MSA.
The LED on the Power/Standby button changes from amber to solid green, indicating that the
MSA has been powered on.
3.
Wait (up to four minutes) for the MSA to complete its startup routine.
NOTE:
If you installed a redundant controller and Fibre Channel I/O module in the MSA, the
CLONE FIRMWARE message might be displayed. Press the > button on the controller to copy the firmware from the right controller (Controller 1) to the left (new) controller
(Controller 2). In redundant configurations, the same firmware version must be installed on each controller.
4.
Press the < and > LCD panel message buttons on the front of each MSA controller, and look for the following message:
01 MSA Startup Complete
NOTE:
Proceed to the next step only after the Startup Complete message is displayed. If the server is powered on before the MSA completes its startup sequence, the server may not properly discover the storage.
5.
Power on (or restart) each server with access to the MSA and log on as a user with administrative control.
6.
Verify that each device in the network is operating properly.
maintenance and service guide 69
Removing power from the MSA
CAUTION:
System power to the MSA does not shut off completely with the power switch. The two positions of the front panel power switch should be considered as
On
and
Standby
, rather than
On
and
Off
. The standby position removes power from most of the electronics and the hard drives, but portions of the power supply and some internal circuitry remain active.
• To remove all power from the system, you must disconnect the power cord from the storage system.
• In systems with multiple power supplies, you must disconnect all the power cords to remove power completely from the system.
To remove power from the MSA, do the following:
1.
Ensure that a known good backup is available.
2.
Schedule a maintenance window.
3.
From the servers in the network, stop all access to the MSA.
4.
Press and hold down the MSA Power On/Standby button for five seconds to place the MSA in
Standby mode.
NOTE:
Placing the MSA in standby mode disables the main power supply output, but still provides auxiliary power (+5V) to the device.

Verifying component failure
Hard drive failure is indicated by an amber Drive Failure LED.
CAUTION:
When replacing a hot-pluggable hard drive, it is important that you follow the guidelines in this section.
Failure to do so could result in data loss and could void your warranty.
CAUTION:
See the following for more information about replacing hard drives:
• Hard drive failure and faulted LUNs
• The HP ProLiant Servers Troubleshooting Guide, available on the Management CD
Removing the component
Follow these guidelines when replacing hard drives:
• Never remove more than one hard drive at a time (two if using RAID 6). When you replace a hard drive, the controller uses data from the other hard drives in the array to reconstruct data on the replacement hard drive. If you remove more than one hard drive, a complete data set is not available to reconstruct data on the replacement drive(s) and permanent data loss could occur.
• Never remove a working hard drive. The amber Drive Failure LED indicates a hard drive that has been failed by the controller. Permanent data loss will occur if a working hard drive is removed while replacing a failed drive.
• Never remove a hard drive while another hard drive is being rebuilt. A drive's Online LEDs flash green (once per second) while it is being rebuilt. A replaced hard drive is rebuilt from data stored on the other hard drives.
• If the system has an online spare drive, wait for it to complete rebuilding before replacing the failed drive. When a hard drive fails, the online spare becomes active and begins rebuilding as a replacement drive. After the online spare has completed Automatic Data Recovery (the online LEDs will be continuously lit), replace the failed hard drive with a new replacement drive. Do not replace the failed hard drive with the online spare. The system will automatically rebuild the replacement hard drive and reset the spare hard drive to an available state.

Replacing the controller, controller cache, or controller battery
The following sections detail procedures for replacing an MSA array controller, controller cache module, or controller cache battery pack:
• Removing the controller cache module
• Removing the controller cache battery pack
• Installing the controller cache battery pack
• Installing the controller cache module
Perform only the steps required for your service event. For example, re-seating an array controller includes

Before you begin
CAUTION:
• Before removing a component or blanking panel from an operational device, make sure that you have the replacement part available. Removing a component or blank impacts the airflow and cooling ability of the device. To avoid possible overheating, insert the new or replacement component within one or two minutes. If the internal temperature exceeds acceptable limits, the device may overheat and automatically shut down or restart.
• Parts can be damaged by electrostatic discharge. Use proper anti-static protection.
CAUTION:
• When replacing a controller, HP recommends that the old cache module be moved to the new controller. In single-controller configurations, if the controller fails, this ensures that disk writes that might have been trapped in the old controller's cache are completed.
• In dual-controller configurations, if a controller fails during an expand process, the old cache module
must
be migrated to the replacement controller to complete the expand process. If this is not done, the array contents are invalid.
• In dual-controller configurations, hot-add or hot-replace a controller or Fibre Channel I/O module only during periods of low I/O. Hot-adding or hot-replacing these modules while under heavy I/O may cause a momentary pause, performance decrease, or loss of access to the MSA while the new controller is starting up. After the startup process is complete, full functionality will be restored.
• In dual-controller configurations, the MSA controller and Fibre Channel I/O modules are hot-pluggable and the MSA does not need to be powered down during the replacement. However, you must first use an MSA management utility, such as the ACU or MSA-CLI to disable the controller before removal.

Verifying component failure
Before replacing the controller, cache module, or battery pack:
• Check the controller LCD display panel for error messages.
• Record any failure LEDs or LCD panel messages for reference purposes.
• Check the controller heartbeat LED (1) . If the LED is not blinking, it might indicate a failure.
• Check the controller fault LED (2) . If the LED is on, it might indicate a failure.

Removing the controller cache module
If your system is equipped with a single controller, and you must replace the controller cache:
• You must schedule a maintenance window and remove power from the system to perform the service.
If your system is equipped with two controllers:
• and you are replacing a cache module with another module of the same size, you can remove one of the controllers and replace the module on that controller while the system is running.
• and you are replacing a cache module with a module of a different size, you must schedule a maintenance window and remove power from the system to then change the cache module on both controllers at the same time. The memory size of the cache modules must be the same on both controllers.
IMPORTANT:
Replacement controllers include a new cache module. Remove the new module from the replacement controller and replace it with the cache module from the failed controller. Using the same cache module completes disk writes trapped in the controller cache.

Removing the controller cache battery pack
The controller cache module has two rechargeable and replaceable Nickel Metal Hydride (NiMH) battery packs. Under normal operating conditions, these should last for three years before replacement is necessary. They are continuously recharged via a trickle charging process whenever the MSA storage system is powered on.
Battery packs protect data on the controller cache module against equipment failure or power outage for up to four continuous days.
78 Customer replaceable components
WARNING!
There is a risk of explosion, fire, or personal injury if the battery pack is incorrectly replaced or mistreated. To reduce the risk:
• Do not attempt to recharge the battery outside of the controller.
• Do not expose to water or temperatures higher than 60˚C.
• Do not abuse, disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
• Replace only with the HP spare designated for this product.
CAUTION:
Do not dispose of batteries, battery packs, and accumulators with general household waste. Use the public collection system or return them to HP, your authorized HP Partners, or their agents.
NOTE:
• Always replace batteries in pairs, not individually.
• Temperature, age, and cache size can affect battery life. This time span also applies if the controller cache module is removed from the array controller. When power is restored to the storage system, an initialization process writes the preserved data to the hard drives. This is particularly important for data that has been cached by a posted-write operation, but has not yet been written to the hard drives.
• Batteries on a new controller might be discharged. In this case, a POST message is displayed on the controller display panel when the controller is powered on, indicating that the controller cache module is temporarily disabled. No user action is required, because internal circuitry automatically recharges the batteries. Recharging the batteries can take up to four hours. The controller functions properly during this time, although without the performance advantage of the controller cache module. When the batteries are charged to 90 percent of their capacity, the controller cache module is automatically enabled.

Configure new storage with the ACU or the CLI. Verify that additional storage is identified through the utility. For instructions, see the ACU or CLI user documents.
6.
Run the operating-system-specific administration utility to add LUNs.
7.
If necessary for your operating system, reboot the server to use the new storage.
Migrating existing storage enclosures
Even though extensive design and testing has been performed, HP recommends backing up data before migrating the enclosure to the MSA. Perform the administrative steps to defragment file systems or volumes prior to performing the backup. This allows more efficient use of your backup media and reduces the time for backup.
Perform the following steps to migrate a new enclosure to an existing MSA:
NOTE:
Only SCSI storage enclosures can be migrated; migration of SATA enclosures is not supported.
1.
After backing up the storage, schedule a convenient time to shut down the servers/applications so the storage subsystem can be turned off.

• Controller firmware is the latest version (recommended).
Before moving an array from one controller to another, the following additional conditions must be met:
• All hard drives in the array must be moved at the same time.
• Positions of hard drives on the destination controller must remain the same during relocation of the array.
When the appropriate conditions are met, perform the following procedure to move the hard drives:
1.
Power Off the MSA storage system as detailed in
.
2.
Move the hard drives.
3.
Power On the MSA storage system as detailed in
4.
The following message should be displayed on the LCD front panel of the controller 86 DRIVE
POSITION CHANGE DETECTED.
IMPORTANT:
If the following LCD message is displayed: 121 NO VOLUMES DETECTED, turn Off system immediately to avoid data loss, and return the hard drives to their original locations.
5.
Check the new configuration by running the ACU or MSA-CLI.

8 Capacity expansion and extension
Array expansion is the addition of physical hard drives to an array that has already been configured. The capacity of these added physical hard drives may then be added to an existing LUN on the array or configured into a new LUN.
LUN extension is the enlargement of an existing LUN after the corresponding array has undergone capacity expansion.
Expansions and extensions are performed through the ACU or MSA-CLI.
If you are using hot-pluggable hard drives, expansion can be performed online (that is, without shutting down the operating system). Online extension can only be performed if supported by the operating system.
CAUTION:
Back up all data before removing hard drives or changing configurations. Failure to do so could result in permanent loss of data.
NOTE:
When extending a LUN under Windows 2000, upgrade the LUN to Dynamic before creating a partition on that LUN. If the LUN already has a partition when it is upgraded to Dynamic, Windows may not allow LUN extension. See the Windows 2000 documentation for details about Dynamic and Basic LUNs.
NOTE:
Windows may allow only four partitions on each LUN. Additional space created may not be accessible if the four partitions per LUN limit is exceeded.
NOTE:
If you are running Windows 2000 with Microsoft Cluster Services (MSCS), LUN extensions are not recommended. MSCS requires that drives be configured as Basic in Logical Disk Manager. To take advantage of LUN extension, your hard drives would have to be configured as Dynamic when the volume is initially created. Because of the differences in requirements for the MSCS and the LUN extension feature, HP recommends that you not perform LUN extensions on storage enclosures that are part of a Microsoft Cluster.

9 Hard drive failures and faulted
LUNs
The purpose of fault-tolerant array configurations is to protect against data loss due to hard drive failure.
Each RAID configuration has inherent limitations on the number of hard drive failures that it can tolerate.
If the fault-tolerance level of a particular LUN or array configuration is exceeded, the array will be locked from any further I/O. This protection is designed to preserve the integrity of the local drive, but does require manual intervention to recover or re-enable the LUN.
Although controller firmware is designed to protect against normal hard drive failure, it is imperative that you perform the correct actions to recover from a hard drive failure without inadvertently introducing any additional hard drive failures.
Included sections:
• Recognizing hard drive failure
• Recovering from compromised fault tolerance (enabling failed LUNs)
• Best practices when replacing hard drives
Recognizing hard drive failure
LEDs on the front of each hard drive are visible from the front of the external storage unit. When a hard drive is configured as a part of an array and attached to a powered-on controller, the status of the hard drive can be determined from the illumination pattern of these LEDs.
For detailed descriptions of the various LED combinations, see
.
Other ways to determine that a hard drive has failed include the following:
• LEDs on the storage system chassis illuminate amber if failed hard drives are inside. (However, this LED also illuminates when other problems occur, such as when a fan fails, a redundant power supply fails, or the system overheats.)
• LEDs on the hard drives illuminate amber if a hard drive has failed or is a member of a faulted LUN.
• Front-panel LCD display messages list faulted LUNs and failed hard drives whenever the system is restarted, as long as the controller detects one or more good hard drives.
• ACU represents faulted LUNs and failed drives with distinctive icons.
• HP-SIM can detect failed hard drives.
• ADU lists all failed hard drives.
For more information on troubleshooting hard drive problems, see the HP ProLiant Servers Troubleshooting
Guide.
Effects of hard drive failure
When a hard 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 hard drive failure. If any physical hard drive in the array fails, all non-fault-tolerant (RAID 0) LUNs in the same array also are failed.
• RAID 1 and RAID 1+0 configurations can tolerate multiple hard drive failures, as long as none of the failed hard drives are mirrored to one another.
• RAID 5 configurations can tolerate one hard drive failure.
maintenance and service guide 99
• RAID 6 configurations can tolerate simultaneous failure of two hard drives in the array.
Compromised fault tolerance
Each RAID configuration has inherent limitations on the number of physical hard drive failures that it can tolerate. If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised.
When the MSA determines that the fault tolerance of a LUN is compromised, the LUN is taken offline and subsequent I/O requests are rejected. This is designed to protect the integrity of the LUN, but does require manual intervention to recover or re-enable the LUN. You are likely to lose data, although it can sometimes be recovered.
Common causes of compromised fault tolerance include:
• More hard drives fail than the LUN can tolerate.
For example, in a RAID 5 array, if a hard 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.
• A SCSI cable could be broken or disconnected.
• A temporary loss of power.
For example, if both power supplies are inappropriately connected to the same power source and that power source it interrupted, fault tolerance may be compromised.
Recovering from compromised fault tolerance (enabling faulted
LUNs)
If fault tolerance is compromised, inserting replacement hard drives does not improve the condition of the logical unit. The procedure to re-enable or accept a LUN that is unresponsive is performed in the Array
Configuration Utility (ACU) or the MSA Command Line Interface (MSA-CLI).
1.
Stop all I/O activity.
2.
Turn off the system as described in
.
3.
Check for loose, dirty, broken, or bent cabling and connectors on all devices.
4.
Remove and then reinsert all hard drives and controllers.
CAUTION:
Data can be lost if the hard drives are not firmly reseated.
5.
Turn the system on as described in
NOTE:
In some cases, a marginal hard drive might work again for long enough to allow you to make copies of important files.
6.
If using the MSA LCD panel:
a. If one of the following messages are displayed on the MSA array controller LCD front panel, an issue was found with one or more configured LUNs that may result in data loss, so all of the hard drives in the LUNs have been disabled. Press the right push button to re-enable the LUNs.
02 ENABLE VOLUME <n>?
'<'=NO, '>'=YES
04 ENABLE VOLUMES ? '<'=NO, '>'=YES
100 Hard drive failures and faulted LUNs
b. Make copies of important data, if possible.
c. Replace any failed hard drives and allow the Automatic Data Recovery (ADR) process to rebuild the data onto replacement drives.
d. After failed hard drives have been replaced, fault tolerance may again be compromised. If so, power cycle the system, and if the #02 or #04 ENABLE VOLUME LCD message is displayed, press the right push button to re-enable the LUNs.
7.
If using the ACU:
a. Open the ACU and highlight the faulted LUN (shown with a red drive symbol.)
b. Select Re-enable Failed Logical Drive.
c. Repeat step a and b for each faulted LUN.
d. Save the configuration and then exit the ACU.
8.
If using the MSA-CLI:
a. Open the MSA-CLI and enter the show units command to display information about all of the LUNs associated with the MSA.
b. Enter accept units to enable all faulted LUNs.
c. Enter show units to verify the status of the LUNs.
d. Exit the MSA-CLI.
9.
Remember that data loss may have occurred and data on the LUN is suspect.
Best practices when replacing hard drives
Before replacing a degraded hard drive consider the following:
• 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.
• In systems that use external storage enclosures, 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.
• When a hot-pluggable hard drive is inserted, all disk activity on the array is paused while the new hard drive is spinning up (approximately 10 seconds). If the hard drive is inserted while power is on, in a fault-tolerant configuration, data recovery onto the replacement hard drive begins automatically
(indicated by the blinking online LED).
• Sometimes, a hard drive that has previously been failed by the controller may seem to be operational after the system is power-cycled, or (for a hot-pluggable drive) after the hard drive has been removed and reinserted. However, continued use of such marginal hard drives may eventually result in data loss. Replace marginal hard drives as soon as possible.
• Back up all data before removing hard drives or changing configurations. Failure to do so could result in permanent loss of data.
• Remove only hard drives that have been failed or marked as degraded by the controller.
To minimize the likelihood of fatal system errors, take these precautions when removing failed drives:
• Do not remove a degraded hard drive if any other member of the array is offline (the online LED is off).
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.
maintenance and service guide 101
• When RAID 6 (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 failed second hard drive from an array until the first failed or missing hard drive has been replaced and the rebuild process is complete. (When the rebuild is complete, the online LED on the front of the hard drive stops blinking.)
Exceptions:
• In RAID 6 (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 hard 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.
If another hard 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 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 through the Array Configuration Utility (ACU) or MSA Command Line Interface (MSA-CLI).
• The amount of I/O activity during the rebuild operation
• The rotational speed of the hard 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 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.
If ADR process aborts, restart the storage system and allow ADR to begin again. If ADR fails again, back up all data on the system, do a surface analysis (using your diagnostics utility), and restore the data from backup.
102 Hard drive failures and faulted LUNs
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 and the storage system. 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.

104 Hard drive failures and faulted LUNs
10 Array controller firmware
Each array controller contains Read-Only Memory (ROM), which holds the firmware that operates the controller. In dual-controller configurations, the two controllers must execute the same firmware version.
Included in this section:
• Determining the currently-installed firmware version
• Updating controller firmware
• Recovering corrupted firmware
NOTE:
After updating MSA controller firmware, be sure to check the status of the MSA for unexpected issues.
Verify the status of the connections, defined profile types, redundancy settings, and storage configuration.
Determining the currently installed firmware version
To determine the firmware version currently running on a controller, do one of the following:
• On the MSA controller LCD panel, use the arrow keys to scroll backwards through the messages until the ARRAY CONTROLLER FIRMWARE VER <version> message is displayed.
• Each time the MSA controller is restarted, view the first message that displays the firmware version.
• In the CLI, use the SHOW VERSION command.
Updating controller firmware
Because the MSA can operate in a variety of operating system environments, several updating methods are available. To perform an update, obtain the following items from the MSA website:
• Controller firmware (on the Software, Firmware & Drivers page.)
• Firmware updating guide (on the Technical Documents page.)
Cloning controller firmware
NOTE:
Cloning is possible only in dual-controller configurations.
Each time a system with two controllers is powered on or restarted, or if a second controller is hot-plugged into a single-controller configuration, the firmware versions on the controllers are compared. If the firmware versions on the two controllers are different, the array controller LCD panel prompts to clone the firmware from one controller to the other, so that they have the same version.
The determination as to which firmware version is used is based on the following criteria:
• If the MSA is being powered up with both controllers inserted, then the most recent version of firmware is used regardless of which controller it resides on.
• If the MSA is already operating and an optional controller is hot-plugged, then the version of firmware that is on the original (non-hot-plugged) controller is used regardless of its version. This ensures that any host-initiated I/O to the controller is not interrupted.
maintenance and service guide 105
If the firmware version on the two controllers is not the same, the following prompt is displayed in the controller LCD panel: CLONE FIRMWARE ? ‘<‘ = NO, ‘>' = YES
If > is pressed or a response is not made to the prompt within 60 seconds, the following messages are displayed on the LCD panel while firmware is copied from the active controller to the standby controller and the standby controller is automatically restarted:
ROM CLONING STARTED
ARRAY CONTROLLER RESTARTING
STARTUP COMPLETE
The two controllers should now operate in redundant mode.
NOTE:
There is the possibility that a specific version of firmware may not be compatible with certain hardware revisions of a controller. In this scenario, the firmware on the two controllers is compared, and the version that is compatible with both controllers is copied to the controller with the incompatible firmware version.
However, if the controller that is updated is already operating and processing I/O, it is not reset. The
MSA does not enter redundant operation and an appropriate message is shown on the display. After the
MSA has been shut down and powered back on, the controllers are then be able to enter redundant operation. On a subsequent power cycle, both controllers enter redundant mode.
Recovering corrupted firmware
If the controller detects a firmware corruption, the following message is displayed on the LCD panel:
ERROR: ROM CORRUPT
SEND IMG VIA XMODEM
To recover the controller, you must obtain a current firmware image and send it to the controller using a serial connection.
1.
Go to the MSA website and obtain the latest controller firmware.
NOTE:
If you are not yet registered, select the option to receive e-mail notifications, advisories, and support alerts about MSA system hardware, firmware, drivers, and software components.
This alert notification system is a one-way broadcasting method used to distribute important notices about HP products. Information about your MSA is not requested when subscribing to this service.
2.
Establish a serial connection to the affected controller:
• Use the custom CLI configuration cable shipped with the MSA.
• Use a terminal emulator program that supports the Xmodem protocol, such as HyperTerminal.
• Use the following emulator connection settings:
• Bits per second: 19200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
A blank emulator window is displayed—no CLI prompt is displayed.
3.
Using the emulator transfer (or send file) command, send the firmware to the controller.
106 Array controller firmware
The following instructions and examples use HyperTerminal. For more information, see user documentation for your emulator program.
a.
On the menu bar at the top of the HyperTerminal window, select Transfer > Send File.
b.
Click Browse and navigate to the location of the firmware image obtained in
c.
Expand the Protocol drop-down box and select 1K XModem.
d.
Click Send.
A status window is displayed.
4.
Wait for the transfer process to complete.
NOTE:
This process may take up to 15 minutes. Do not interrupt this process.
5.
Wait for the controller to automatically restart.
maintenance and service guide 107
6.
In dual-controller configurations only, if the newly installed firmware on the recovered controller differs from the firmware on the active controller, the CLONE FIRMWARE LCD message is displayed.
See
108 Array controller firmware
11 SCSI hard drive firmware
SCSI hard drive firmware updates are performed from the bootable ProLiant Firmware Maintenance CD and are required only when the following message is displayed on the MSA controller LCD panel:
85 BAD DRIVE FRMWARE BOX <n> BAY <n>
CAUTION:
This update procedure must be performed during a scheduled maintenance window.
1.
Obtain the ISO image for the ProLiant Firmware Maintenance CD from the following website: http://www.hp.com/support/proliantstorage . Then, burn the image onto a bootable CD using a standard CD-ROM burning utility. Do not simply copy the ISO file to a blank CD.
NOTE:
If the latest Firmware Maintenance CD does not include the latest release of hard drive firmware contained in a Smart Component, the CD can be used in combination with the latest individual Smart
Component package to perform the update.
2.
Insert the CD into the CD-ROM hard drive of a ProLiant server with access to the MSA.
3.
Following standard precautions, remove power from the server. For instructions, see
4.
Reapply power to the server.
5.
Allow the server to boot to the Firmware Maintenance CD, and then follow the onscreen instructions to upgrade the firmware on the hard drives.

Federal Communications Commission notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (i.e., personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls into. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label.

Electrostatic discharge
To prevent damage to 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.
Preventing electrostatic damage
To prevent electrostatic damage, observe the following precautions:
• 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 (see
“
”).
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts: maintenance and service guide 115
• 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 HP authorized reseller install the part.
