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.

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 system.
•
Do not use conductive tools that could bridge live parts.
•
Remove all watches, rings, or loose jewelry when working in hot-plug areas of an
energized device.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives
and the internal system components to cool before touching them.
CAUTION: Protect the device 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 system in operation
during a power failure.
Weight Warning
WARNING: The MSA500 system weighs 22.7 kg (50 lb) when assembled for
shipping. To reduce the risk of personal injury or damage to equipment:
22.7 kg

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:
www.hp.com
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
