Create a mount point (as root) where you will mount the SRP device. For
example:
example:
# mkdir /mnt/targetname
# mount /dev/sde1 /mnt/targetname
# mount /dev/sde1 /mnt/targetname
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

, providing virtual Ethernet connectivity.
The VNIC driver, along with QLogic EVIC’s two 10 Gigabit ethernet ports, enables
Infiniband clusters to connect to Ethernet networks. This driver also works with the
earlier version of the I/O controller, the VEx.
Infiniband clusters to connect to Ethernet networks. This driver also works with the
earlier version of the I/O controller, the VEx.
The QLogic VNIC driver creates virtual Ethernet interfaces and tunnels the
Ethernet data to/from the EVIC over InfiniBand using an InfiniBand reliable
connection.
Ethernet data to/from the EVIC over InfiniBand using an InfiniBand reliable
connection.
The virtual Ethernet interface supports any Ethernet protocol. It operates like any
other interface: ping, ssh, scp, netperf, etc.
The VNIC interface must be configured before it can be used. To do so, perform
the following steps:

Discover the EVIC/VEx Input/Output Controllers (IOCs) present on the fabric
using the ib_qlgc_vnic_query command. For writing the configuration
using the ib_qlgc_vnic_query command. For writing the configuration
file, you will need information about the EVIC/VEx IOCs present on the
fabric, such as 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
fabric, such as 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. Run
it as a root user. For example:
