Summary of Configuration Files
Table F-7 contains descriptions of the configuration and configuration template
files used by the InfiniPath and OpenFabrics software.
nguid The number of GUIDs that are used. If nguids == 2 and two chips
are discovered, the first chip is assigned the requested GUID (from
eeprom, or ipath_sma), and the second chip is assigned GUID+1.
serial The serial number of the QHT7140, QLE7140, QLE7240, or
QLE7280 adapter.
unit A unique number for each card or chip in a system.
status The numeric version of the status_str file, described in Table F -5.
Table F-7. Configuration Files
Configuration File Name Description
/etc/infiniband/qlgc_vnic.cfg VirtualNIC configuration file. Create this file
after running ib_qlgc_vnic_query to
get the information you need. This file was
named /etc/infini-
band/qlogic_vnic.cfg or
/etc/sysconfig/ics_inic.cfg in
previous releases. See the sample file
qlgc_vnic.cfg.sample (described
below) to see how it should be set up.
