Removal and Replacement Procedures  
Rack Warnings and Cautions  
WARNING: Because the rack allows stacking of computer components on a vertical  
rather than horizontal plane, be sure 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 throughout the installation instructions provided with the device.  
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.  
Always 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 the stabilizing feet to the rack if it is a single-rack installation.  
The racks are coupled together in multiple-rack installations.  
Fully extend the bottom stabilizers on the equipment. Be sure that the equipment is  
properly supported/braced when installing options and boards.  
Be sure that the rack is adequately stabilized before extending a component  
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 kg (253 lb), is over 2.1m (7 ft) tall, and may 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.  
Device Warnings and Cautions  
Before installing a system, be sure that you understand the following warnings and cautions.  
WARNING: To reduce the risk of personal injury or damage to the equipment, observe  
all warnings and cautions throughout this chapter.  
WARNING: Do not exceed the level of repair specified in the procedures in the product  
documentation. All troubleshooting and repair procedures are detailed to allow only  
subassembly or module-level repair. Because of the complexity of the individual  
boards and subassemblies, do not attempt to make repairs at the component level or to  
make modifications to any printed wiring board. Improper repairs can create a safety  
hazard.

Removal and Replacement Procedures  
Hot-Plug SCSI Hard Drive  
CAUTION: If you must replace a hot-plug drive, follow the guidelines in this section. Failure  
to do so can result in data loss and can void the warranty.  
RAID 0 is not a fault-tolerant configuration. Never remove a drive from a RAID 0 array  
unless it has failed. Drive failure is indicated by an amber drive failure LED. In a RAID 0  
configuration, removal of an operating drive results in data loss. To remove a drive without  
losing data, always back up the entire array, replace the drive, and restore the entire array.  
Backing up a single drive and replacing it does not restore the array.  
Some instances exist in which you may replace a drive in RAID 1, 5, and Advanced Data  
Guarding configurations. To determine when drive replacement is possible without data loss,  
use the hot-plug SCSI hard drive LEDs combination table in Chapter 4, “Component  
Identification.”  
Follow these additional guidelines when replacing drives:  
Never remove more than one drive at a time (or two drives if you are using  
Advanced Data Guarding). When you replace a drive, the controller uses data from the  
other drives in the array to reconstruct data on the replacement drive. If you remove more  
than one 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 drive while the controller is rebuilding another drive. A drive’s  
online LED flashes green while it is being rebuilt. The controller requires the data from  
all other drives to rebuild the replacement drive.  
If the system has an online spare drive, wait for it to complete rebuilding before  
replacing the failed drive. When a 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 LED is continuously lit), replace the failed drive with a new  
replacement drive. Do not replace the failed drive with the online spare. The system  
automatically rebuilds the replacement drive and resets the spare drive to an available  
state.  
If you replace a drive while the system is off, it may be necessary to rebuild the  
replaced drive.

Diagnostic Tools  
Server Utilities  
HP utilities provide reporting functions that enable event-focused management and  
diagnostics. To install and run these utilities, refer to the server documentation.  
Diagnostics Utility—This utility tests and verifies proper operation of the system  
hardware. If problems are found, the utility isolates failure(s) down to the replaceable  
part, whenever possible. When an operating system is installed with SmartStart  
Version 5.30 or later, the Diagnostics and utilities are installed on a partition of the hard  
drive that contains the operating system. (This hard drive may or may not be located in  
the storage system.) Always access these utilities when a system configuration error is  
detected during POST.  
INSPECT Utility—This utility provides a report detailing system information.  
Insight Manager 7—This Web-based application enables system administrators to  
accomplish normal administrative tasks from any remote location, using a Web browser.  
Insight Manager 7 provides device management capabilities that consolidate and  
integrate management data from HP and third-party devices.  
Insight Management Agents—These agents enable easy manageability of the server  
through Insight Manager 7 software and third-party SNMP management platforms.  
Management agents monitor key subsystems that are instrumental in making health,  
configuration, and performance data available to the agent software. The agents act upon  
that data by initiating alarms in the event of faults. The agents also provide updated  
management information, such as network interface or subsystem performance statistics,  
to the management systems.  
Survey Utility—This utility gathers critical hardware and software information on  
servers running Microsoft® Windows® and Novell NetWare operating systems. If a  
significant change occurs between data-gathering intervals, the Survey Utility marks the  
previous information and overwrites the Survey text files to reflect the latest changes in  
the configuration.

Diagnostic Tools  
ROM Upgrades  
Each MSA500 controller has a ROM that contains the controller firmware.  
The ROM flash tool enables system administrators to efficiently upgrade array controller  
ROM images. This tool has the following features:  
Supports Microsoft Windows NT® 4.0, Windows 2000, Novell NetWare (offline only),  
and Linux operating systems  
Integrates with other software maintenance, deployment, and operating system tools  
Automatically checks for hardware, firmware, and operating system dependencies, and  
installs only the correct ROM upgrades required by each target controller  
For firmware procedures, refer to the SmartStart CD.  
Array Diagnostics Utility  
ADU collects all possible information about the array controllers in the system and generates  
a list of detected problems. You can save this data to a file for analysis. In most cases, ADU  
provides sufficient information for troubleshooting procedures.  
To obtain ADU, download the utility from the HP website:  
Array Configuration Utility  
ACU Version 6.0 (or later) is a browser-based utility with the following features:  
Supports online array capacity expansion, logical drive capacity extension, assignment of  
online spares, and RAID or stripe size migration  
Suggests the optimum configuration for an unconfigured system  
Provides different operating modes, enabling faster configuration or greater control over  
the configuration options  
Remains available any time that the server is on  
Displays on-screen tips for individual steps of a configuration procedure  
The minimum display settings for optimum performance are 800 × 600 resolution and 256  
colors. The server must have Microsoft Internet Explorer 5.5 (with Service Pack 1) installed  
and be running Microsoft Windows 2000, Windows NT 4.0, or Linux. Refer to the  
README.TXT file for further information about browser and Linux support.  
For more information about ACU Version 6.0 (or later), refer to the HP Array Configuration  
Utility User Guide on the Documentation CD.

NetWare Online Array Configuration Utility (CPQONLIN)  
The NetWare Online Array Configuration Utility, also called CPQONLIN, is a NetWare  
Loadable Module (NLM) for configuring drive arrays without shutting down the server.  
CPQONLIN also provides information about the status of drives attached to the MSA500  
controller. It indicates drive failure, expansion, or waiting for expansion or rebuild (queued).  
For more NetWare Online Array Configuration Utility information, refer to the HP  
StorageWorks Modular Smart Array 500 System User Guide or the HP Array Configuration  
Utility User Guide on the Documentation CD.
