Understanding Diagnostic Tools
This chapter includes the following sections:
About Diagnostic Tools
You can use diagnostics tools to diagnose hardware problems with your Cisco servers. The user interface displays the status of the test run and examines log files for troubleshooting hardware issues.
Diagnostic tools allows you to:
- Run tests on various server components to find out hardware issues along with analysis of the test results in a tabular format.
- Run all the tests using the Quick Tasks functionality without browsing through available tests.
- Run tests serially, as running some tests in parallel may interfere with other tests.
- Configure the test by entering different argument values other than the default ones
- Select tests you want to run using the Test Suite functionality.
- Save all the tests logs, such SEL logs, to an external USB flash drive.
- Probe the current state of the server and view hardware issues.
Diagnostic Component | Function |
---|---|
Quick Test |
Use this test when you want to quickly check the status of a subsystem within a stipulated period. The components that can be tested under the quick test are processor, cache, memory, disk, video, network, QPI, CIMC, RAID, and chipset. |
Comprehensive Test |
Use this test when you want to test a subsystem in detail. These tests are designed to stress the subsystems and report the error. The tests that can be run are processor, memory, QPI, disk, and non-uniform memory access (NUMA). |
Quick Tasks |
Allows for consolidated testing of both comprehensive and quick tests. You can run both types of tests using quick tasks. |
Test Suite |
All the tests available under the quick and comprehensive test are available here. The test suite gives you an option to choose as many tests as you like (using a check box) and running them together. |
Tests Log Summary |
Use the test log summary to view the log, error log, and analysis of all the tests you have run. You can use four filters to sort the logs. |
Tests Summary |
This table on the left-hand navigation gives you the results of the tests you have run in the form of either passed tests, tests in queue or failed tests. |
Using Diagnostic Tools
Quick Tests
You can run these tests quickly to determine any hardware issue. These tests usually take 20-30 minutes to run and test limited functionality for a few subsystems. The comprehensive test provides more exhaustive diagnostics.
To run the quick test follow these steps:
Comprehensive Test
The Comprehensive test can run for hours and usually runs when quick tests cannot diagnose the issue with your server. The test is designed to test multiple hardware components and find issues that may be caused due to multiple components on your server.
The individual tests run can be customized to test some user-defined conditions. You can also select a group of tests to be run.
To run the comprehensive test, follow these steps:
Step 1 | Click Diagnostic Tools from the left navigation pane. | ||||||||||||||
Step 2 | Click Tests. | ||||||||||||||
Step 3 | Click a subsystem (such as processor, memory, or network). | ||||||||||||||
Step 4 |
On the content pane, click Run Tests. The test is run and the status is displayed in the Tests Status area.
|
Quick Tasks
Quick Tasks allow you to get started with diagnostic tools immediately. You can run all the tests (Quick and Comprehensive) from here and report the details to Cisco to troubleshoot the logs and provide information about problems with your system. To use this feature, follow these steps:
Step 1 | Click Diagnostic Tools from the left navigation pane. |
Step 2 | Click Quick Tasks. |
Step 3 |
Select either Run Quick Tests or Run Comprehensive Test from the toolbar. The status appears in the Test Status pane. You can also view detailed test results under Tests log summary. |
Tests Suite
The Test Suite allows you to run the quick test and comprehensive test in a batch. It lists the various tests available, along with the test type and description of the test. You can select any number of tests you want to run from the list and view the result in the Tests Status column.
To run the test suite, follow these steps:
Step 1 | Click Tests Suite from the left navigation pane |
Step 2 | Select the tests you want to run by clicking the required check boxes. |
Step 3 |
Click Run Tests Suite to run the tests you added to the test suite. The status appears in the Tests Status pane along with the name, suite ID, Result, start time and end time. You can also view the Tests Log Summary to view the execution status of the tests in the test suite. |
Tests Log Summary
Use the Tests Log Summary functionality to examine the test logs for troubleshooting. To view the Tests Log summary, follow these steps:
Step 1 | Click Diagnostic Tools on the left navigation pane. |
Step 2 | Click Tests Log Summary on the left navigation pane. |
Step 3 | Select a filter from the filter drop-down and click Go. The status, result, start time, and end time of the test displays. |
Step 4 | Click a specific log entry (for example, click memory test) for more details. |
Step 5 | The Log, Error Log (if the test failed), and the analysis of the specific test appears in the content pane. |
Tests Summary
The Test Summary table in the left navigation area provides you with a quick view of the tests that have passed, tests in queue and tests that have failed
