OpenFabrics Drivers and Services Configuration and Startup
S
NOTE:
The configuration must be repeated each time the system is rebooted.
/etc/sysconfig/infinipath. Change this line to:
IPOIB_MODE="datagram"
Restart infinipath (as root) by typing:
#/etc/init.d/infinipath restart
The default IPOIB_MODE setting is "CM" for Connected Mode.
Configuring and Administering the VNIC Interface
The VirtualNIC (VNIC) Upper Layer Protocol (ULP) works in conjunction with firmware running on Virtual Input/Output (VIO) hardware such as the SilverStorm Ethernet Virtual I/O Controller (EVIC™) or the InfiniBand/Ethernet Bridge Module for IBM® BladeCenter®, providing virtual Ethernet connectivity.
The VNIC interface must be configured before it can be used. To do so, perform the following steps:
1.Discover EVIC/VEx Input/Output Controllers (IOCs) present on the fabric using ib_qlgc_vnic_query. For writing the configuration file, you need information about the EVIC/VEx IOCs present on the fabric, for example, their IOCGUID, IOCSTRING, etc. Use the ib_qlgc_vnic_query tool to get this information.
When ib_qlgc_vnic_query is executed without any options, it displays detailed information about all the EVIC/VEx IOCs present on the fabric. For example:
