HP bc2100 ATCA Server Blade Diagnostics Features
The diagnostics are based on the Intel
®
Modular Test Architecture (Intel
®
MTA) for Linux*, an execution
environment and framework for Intel
®
architecture (IA) platforms running on a Linux Service OS. This
framework consists of test executives and test modules written as Linux applications. The test executives use
a text configuration file to describe the tests available and use either a Graphical User Interface (GUI) or
command line arguments to specify test options. The test modules use a standard test services library to
receive test parameters from the test executive and report status and test results in a consistent manner.
The diagnostics run locally on the Server Blade in an offline mode on a Linux Service OS. The board is
instructed to reboot into the Service OS and the diagnostics are loaded and run. The diagnostics interrogate
the board and compare the results to known valid values that are configured in a test package. If the tests
find variances between the board test results and the test package, the diagnostic test fails. The diagnostics
come with default test packages, but need to be reconfigured to represent the final configuration of the board.
Once the diagnostics are complete, the results are captured for viewing in output files. Tests are provided for
the following server blade components:
•BMC
•CPU
• Memory
•Cache
•Disk
•USB
•PCI
• System Management BIOS information
• Network Interface Card (NIC)
Refer to the user interface and syntax section for more information on running the tests.
Server Blade Diagnostics Performance
The time required to complete each diagnostic test will vary depending on the blade configuration. In general,
most of the individual tests should run to completion (from several seconds to up to one minute). However,
memory, cache and disk tests can take much longer, depending on the size of the memory, cache or disk being
tested.
See individual test descriptions in the module help files provided with the Service OS diagnostic test package
for expected performance of each subtest in a standard configuration.
Server Blade Diagnostics Security
Access to the diagnostic service OS is restricted by user login and passwords, which can be altered within the
provided ISO image by the system administrator.
