C.9.4

boardversion

It may be useful to keep track of the current version of the installed software. You can check the version of the installed InfiniPath software by looking in:

/sys/bus/pci/drivers/ib_ipath/00/boardversion

Example contents are:

Driver 2.0,InfiniPath_QHT7140,InfiniPath13.2,PCI 2,SW Compat 2

This information is useful when for reporting problems when requesting support.

NOTE: This file returns information on which form factor adapter is installed. The HTX full height short form factor is referred to as the QHT7040, the HTX low profile form factor is referred to as the QHT7140, and the PCIe half height short form factor is the QLE7140. This information will make it easier for Support to help with any problems.
