Installation Troubleshooting
The following sections contain information about issues that may occur during
installation. Some of this material is repeated in the Troubleshooting appendix of
the QLogic HCA and InfiniPath Software User Guide.
Many programs and files are available that gather information about the cluster,
and can be helpful for debugging. See appendix D, Useful Programs and Files, in
the QLogic HCA and InfiniPath Software User Guide.
Hardware Issues
Some of the hardware issues that may occur during installation are described in
the following sections. Use the LEDs, as described in “LED Link and Data
Indicators” on page 5-29, to help diagnose problems.
Node Spontaneously Reboots
If a node repeatedly and spontaneously reboots when attempting to load the
InfiniPath driver, it may be because the QLogic adapter is not installed correctly in
the HTX or PCI Express slot.
Some HTX Motherboards May Need Two or More CPUs in Use
Some HTX motherboards may require that two or more CPUs be in use for the
QLogic adapter to be recognized. This is most evident in four-socket
motherboards.
BIOS Settings
This section covers issues related to BIOS settings.The two most important
settings are:
Advanced Configuration and Power Interface (ACPI). This setting must be
enabled. If ACPI is disabled, it may cause initialization problems, as
described in the Troubleshooting section of the QLogic HCA and InfiniPath
Software User Guide.
Memory Type Range Registers (MTRR) mapping must be set to Discrete.
Using a different setting may result in reduced performance. See “MTRR
Mapping and Write Combining” on page A-2 for details.
