2 Removal and Replacement Procedures To service the MSA500 system, you may need the following tools: • Flat-blade screwdriver • From the SmartStart CD: — Advanced Diagnostics Utility (ADU) — ROM Update Utility Safety Considerations Before performing service procedures, review all the safety information. 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.
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.
Removal and Replacement Procedures WARNING: Be sure that the AC power supply branch circuit that provides power to the rack is not overloaded. Not overloading AC power to the rack power supply circuit reduces 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.
Removal and Replacement Procedures System Power Down WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power cord to remove power from the system. The front panel Power On/Standby button does not completely shut off system power. Portions of the power supply and some internal circuitry remain active until AC power is removed. IMPORTANT: If installing a hot-plug device, it is not necessary to power down the system. To power down the system: 1.
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.
Removal and Replacement Procedures To remove the component: 1. Be sure that the online and activity LEDs on the failed drive are both off. CAUTION: To prevent improper cooling and thermal damage, do not operate the system unless all bays are populated with either a component or a blank. 2. Remove the failed drive. 3 2 1 To replace a hot-plug SCSI hard drive: 1. Slide the drive into the bay until it locks into place. 2. Close the lever. CAUTION: Data loss can occur if the drive is not firmly seated. 3.
Removal and Replacement Procedures Universal Hot-Plug Tape Drive To remove the component: CAUTION: To prevent improper cooling and thermal damage, do not operate the system unless all bays are populated with either a component or a blank. CAUTION: Installation of the tape drive height converter is permanent. Attempting to remove the converter after installation voids the tape drive warranty. 1 2 To replace the Universal Hot-Plug Tape drive: 1.
Removal and Replacement Procedures Bezel Blank To remove the component: CAUTION: Always populate bays with either a component or blank. Proper airflow can only be maintained when the bays are populated. Operating the system with unpopulated bays can lead to improper cooling and thermal damage. 1 2 3 To replace the bezel blank: 1. Slide the bezel blank into the bay until it locks into place. 2. Close the lever.
Removal and Replacement Procedures HP StorageWorks Modular Smart Array 500 Controller When the MSA500 controller in a single-controller system fails, HP recommends that you migrate the cache module to a new controller. Battery-backed cached data in a failed controller can remain intact for up to 3 days with 256-MB modules or up to 4 days with 128-MB modules.
Removal and Replacement Procedures Battery-Backed Cache Module CAUTION: To prevent data loss or equipment damage, follow the instructions in this procedure. To remove the component: 1. Determine if the controller configuration supports hot-plug cache replacement: — If the system is equipped with a single controller, power down the system before performing step 2. Refer to “System Power Down” in this chapter.
Removal and Replacement Procedures Blower To remove the component: WARNING: The blower blades rotate at a high speed. Avoid touching the rotating blades when removing the blower. NOTE: The power supply is designed so that removing a blower does not adversely affect system performance. However, do not remove a blower until the replacement blower is available. 1 2 1 To replace the blower: 1. Align the guidepost on the blower with the connector on the power supply.
Removal and Replacement Procedures Hot-Plug Power Supply Observe the following cautions for AC power supplies: CAUTION: Removing a power supply significantly changes the airflow within the enclosure. The system will shut down to prevent overheating unless the power supply is replaced within 5 minutes. CAUTION: Handle the blower carefully to avoid damaging the housing. • Do not press on the center section of the blower because this action can damage the blades. Press only on the outer edge of the blower.
Removal and Replacement Procedures To remove the component: 1. Disconnect the power cord from the power supply. 2. Remove the blower. Refer to “Blower” in this chapter. 3. Remove the power supply. 1 2 To replace the power supply: 1. Lift the locking latch. 2. Slide the power supply into the bay until it locks into place. 3. Install the blower on the power supply. 4. Connect the power cord.
Removal and Replacement Procedures 2-Port and 4-Port Shared Storage Modules To remove the component: 1. Power down the system. Refer to “System Power Down” in this chapter. 2. Disconnect the SCSI cabling connected to the 2-Port Ultra3 SCSI I/O module. 3. Remove the module. 1 2 To replace the component, reverse the removal procedure.
Removal and Replacement Procedures Interconnect Blank To remove the component: CAUTION: Always populate interconnect bays with a blank. Proper airflow can only be maintained when the bays are populated. Operating the system with unpopulated bays can lead to improper cooling and thermal damage. 1 2 To replace the component, reverse the removal procedure.
Removal and Replacement Procedures Power Button/LED Assembly To remove the component: 1. Power down the system. Refer to “System Power Down” in this chapter. 2. Remove the hot-plug SCSI hard drives in bays 10 through 14. Refer to “Hot-Plug SCSI Hard Drive” in this chapter. IMPORTANT: To press the plastic latches behind the front bezel, you may choose to use a flat-head screwdriver. 3.
Removal and Replacement Procedures MSA500 System Chassis and Backplane If the backplane board fails or the chassis sustains significant damage, you must order a replacement chassis. To replace the chassis and backplane: 1. Power down the system. Refer to “System Power Down” in this chapter. 2. Remove all installed hard drive blanks. Refer to “Hard Drive Blank” in this chapter. 3. Remove all installed hot-plug SCSI hard drives. Refer to “Hot-Plug SCSI Hard Drive” in this chapter. 4.
3 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.
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.
Diagnostic Tools 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).
