| HP provides several tools and utilities that will help you with several of the steps in the HP troubleshooting methodology described previously in this chapter. You should be familiar with the capabilities and functions of the following products: Integrated Management Log Integrated Management Log Viewer Integrated Management Display Integrated Management Display Utility Enhanced Integrated Management Display Service HP Server Diagnostics
22.4.1 Integrated Management Log The HP Integrated Management Log (IML) is a utility integrated into the server to record all server-specific events. Events are abnormal system occurrences. The log tracks events recorded by the health drivers, such as operating system information and ROM POST codes. This nonvolatile (that is, information is recorded to a file rather than being stored in volatile memory) log records events and errors for a post-diagnosis review, thus helping system administrators to identify server failures promptly. The information displayed for each log entry includes a description of the event, the number of times this specific event has occurred, the initial time and date the event occurred, and the time and date the event was last updated. 22.4.2 Integrated Management Log Viewer The HP Integrated Management Log Viewer is a utility that enables you to view and manage the IML system event entries on a local or remote system. This utility is based on client/server architecture. It can run on any machine and connect to any machine on the network that is running the HP ProLiant Remote Monitor Service. By using the viewer, you can accomplish the following tasks in relation to the IML entries: Sort by description, class, severity, count, update time, and initial time Filter by class, severity, update time, and initial time Print the entries Export the information to a comma-separated file (for import into third-party applications such as spreadsheets) or save the information in a binary format for viewing at a later date or different location
In addition to manipulating the displayed entries, you can also effect changes to the IML on a system. With appropriate administrator privileges, you can accomplish the following tasks: Enter maintenance notes Mark selected entries as repaired Clear the IML of all entries (effectively deleting the log from nonvolatile memory) Acknowledge pending alerts on the Integrated Management Display (IMD)
The Integrated Management Log Viewer is available for the following platforms: ! Important Invoking the IML Viewer on a Windows 2000 server to remotely view the IML on a Windows NT 4.0 server (and vice versa) is not supported. However, the IML logs can be viewed locally at the server or remotely using HP Insight Manager 7.
22.4.3 Integrated Management Display The HP Integrated Management Display (IMD) is an optional peripheral on the front of legacy servers. The IMD provides the following useful benefits: Displays server processes such as power-up, POST, and errors Simplifies management with the capability to report or alert from an endless list of critical events Improves server manageability and uptime by providing easy-to-read information without the use of a monitor Simplifies menu navigation Enables users to display customized information Integrates easily in rack-mounted servers
22.4.4 Integrated Management Display Utility The HP Integrated Management Display Utility enables you to set the text displayed on the IMD. This utility is based on client/server architecture. It can run on any machine and connect to any machine on the network that is running the HP Remote Monitor Service. The Integrated Management Display Utility is available for the following platforms: Windows Server 2003 Windows 2000 Windows NT 4.0 Novell NetWare
22.4.5 Enhanced Integrated Management Display Service The HP Enhanced Integrated Management Display Service is different from the Integrated Management Display Utility in that it enables you to view multiple items in the IMD Idle screen of the IMD. The Enhanced Integrated Management Display Service is available for the following platforms: Windows Server 2003 Windows 2000 Windows NT 4.0
22.4.6 HP Server Diagnostics HP Server Diagnostics is a resource for server testing and problem resolution. The Test Computer feature of it provides diagnostic tests for system components. Use this feature to Server Diagnostics can test more components than the Embedded Diagnostic Utility available from the System Maintenance menu. Note You can access the System Maintenance menu by pressing F10 when prompted during POST.
22.4.6.1 TEST COMPUTER Test Computer provides three types of diagnostics routines, described in the following table. Routine | Description |
|---|
Quick Check Diagnostics | This option will run high-level diagnostics on all detected hardware in the system. However, any errors found with this test would most likely be hard failures and would have already been reported during POST. In such a case, running diagnostics would not be necessary because the POST code will detail the failure. | Automatic Diagnostics | This option is most useful for burn-in testing of all devices. The "continuous looping" feature continues testing all devices until it is stopped by pressing Ctrl+Break; or, if the Stop on Errors option is checked, until it finds an error with a device. Unattended testing without continuous looping will run all tests once and then stop. | Prompted Diagnostics | Use this option to test individual devices. This proves most useful in troubleshooting intermittent errors, such as a high number of error checking and correcting (ECC) memory errors or problems with a drive. It can also be used to verify that a particular component has failed and that its replacement is fully operational. |
Note These diagnostic tests were written specifically for HP-supplied equipment. For accurate results, remove any third-party equipment in the unit before testing.
22.4.6.2 DIAGNOSTIC TESTS Any of the three routines of Test Computer can perform the tests listed in the following table. Test | Function |
|---|
Primary Processor Test | 100 Series error codes. Identifies failures with processor and system board functions. To ensure they are working properly, corrective action may require replacement of the following: System boards or processor assemblies Numeric coprocessor DMA controller Interrupt controller Port 61 CMOS RAM CMOS interrupt CMOS clock Refresh detect signal System speaker, and speaker, to ensure that they are working properly
| Memory Test | 200 Series error codes. The System Memory Test will run the following address tests (tests only the first 16MB in the system) to check the functionality of the address lines: Write, Read, Compare Test Uses static patterns to exercise memory. Noise Test Checks the integrity of data transfer through data lines. Random Data Pattern Test Uses random data patterns to exercise memory. Random Address Test Uses random data patterns written to random addresses to exercise memory. Random Long Test Uses four patterns to exercise long memory. It scans 1MB of memory after testing each test block, looking for errors induced in other locations. This test takes up to 10 minutes per megabyte. Corrective action may require replacement of the memory expansion board, the memory modules, or the processor assembly.
| Keyboard Test | 300 Series error codes. | Parallel Printer Test | 400 Series error codes. | Diskette Drive Test | 600 Series error codes. | HP Smart Array Controller Test | The following options are under the HP Smart Array Controller Test: Drive Monitoring Diagnostic Test Performs a check on the drive monitoring functionality. Controller Diagnostic Test Verifies that the hard drive controller can be accessed and is functional. Seek Test Performs sequential seeks over the hard drive, and then performs random seeks. Read Test Performs a random head seek test followed by a test of the hard drive and reports the number of unusable tracks, if any. Select All the Above Tests Runs the Drive Monitoring Diagnostic Test, the Controller Diagnostic Test, the Seek Test, and the Read Test. Surface Analysis Performs multiple write/read/compares on each track of the drive in search of more unusable tracks. It de-allocates sectors or formats tracks to be unusable when errors are found.
| Serial Test | 1100 Series error codes. | Modem Communications Test | 1200 Series error codes. | Fixed Disk Drive Test | 1700 Series error codes. | Tape Drive Test | 1900 Series error codes. | Advanced VGA Board Test | 2400 Series error codes. | 32-Bit DualSpeed NetFlex-2 Controller and 32-Bit DualSpeed Token Ring Controller Test | 6000 Series error codes. | SCSI Fixed Disk Drive Test | 6500 Series error codes. | CD-ROM Drive Test | 6600 Series error codes. | SCSI Tape Drive Test | 6700 Series error codes. | Server Manager/R Board Test | 7000 Series error codes. | Pointing Device Interface Test | 8600 Series error codes. |
