Summary and Descriptions of Useful Files
Useful files are summarized in Tabl e F-4. Names in blue text are linked to a
corresponding section that provides further details.
boardversion
It is useful to keep track of the current version of the chip architecture. You can
check the version by looking in this file:
/sys/class/infiniband/ipath0/device/boardversion
Example contents are:
ChipABI 2.0,InfiniPath_QLE7280,InfiniPath1 5.2,PCI 2,SW Compat 2
This information is useful for reporting problems to Technical Support.
status_str
Check the file status_str to verify that the InfiniPath software is loaded and
functioning. The file is located here:
/sys/class/infiniband/ipath0/device/status_str
Table F-4. Useful Files
File Name Function
boardversion File that shows the version of the chip architecture.
status_str File that verifies that the InfiniPath software is loaded and
functioning
/var/log/messages Logfile to which various programs write messages. Tracks
activity on your system
version File that provides version information of installed soft-
ware/drivers
NOTE:
This file returns information on which the form factor adapter is installed. The
HTX low-profile form factor is referred to as the QHT7140. The PCIe
half-height, short form factor is referred to as the QLE7140, QLE7240, or
QLE7280.
