IPU-POD

MANUAL INSTALLATION TESTS
You will need to run these tests on each IPU-POD
64
.
There is a division of responsibility between BMC management and V-IPU management when it comes to which
parts of the system that they test.
BMC has support for chassis management, which means that it can verify correct hardware behaviour on most
functional blocks within the chassis.
V-IPU management has support for connectivity tests and focuses on verifying correct cables, cabling for IPU-
Links and GW-Links, as well as for the cabled IPU-Link network.
In combination, these two areas of built-in self-tests (BISTs) will cover most of the needs for system installation
verification.
6.1 Running system tests
The
rack_tool
utility is included as part of the IPU-M2000 software release bundle. See the
for details on how to use
rack_tool
before running these tests. This is especially important if the tests are to be
run on a system that has active users.
•
rack_tool bist
: performs BMC chassis hardware testing
•
rack_tool vipu-test
: performs V-IPU connectivity related tests
6.2 Troubleshooting
This section contains useful information about what to do if you encounter problems while installing and testing
the rack. If you can’t find the answer to your query here and are still experiencing problems, then please contact
your Graphcore representative or use the resources on the Graphcore
.
6.2.1 BMC BISTs
To run the BMC BIST tests, run the following command:
$
./rack_tool.py bist
This test will generate a very low level hardware verification report that will need to be analysed by Graphcore
support in case any errors are reported. The logs are located at “./logs” relative to the current directory where the
command is executed.
• The command reports “Done BIST on ...” if the test is successful.
• The command reports “Failed BIST on ...” if the test fails.
• The command will point to the log file name generated in both cases.
