iSCSI Offload in Linux Server

where the
iface
file includes the following information for RHEL 5.4, RHEL 5.5,
and SLES 11 SP1:
iface.net_ifacename = ethX
iface.iscsi_ifacename =
<iface file>
iface.hwaddress = XX:XX:XX:XX:XX:XX
iface.ipaddress = XX.XX.XX.XX
iface.transport_name = bnx2i
Ensure that the iface.hwaddress is in lower case format.
VLAN Configuration for iSCSI Offload (Linux)
iSCSI traffic on the network may be isolated in a VLAN to segregate it from other
traffic. When this is the case, you must make the iSCSI interface on the adapter a
member of that VLAN.
Modifying the iSCSI iface File
To configure the iSCSI VLAN add the VLAN ID in the iface file for iSCSI. In the
following example, the VLAN ID is set to 100.
#Begin Record 6.2.0-873.2.el6
Iface.iscsi_ifacefile name = <>
Iface.ipaddress = 0.0.0.0
Iface.hwaddress = <>
Iface.trasport_name = bnx2i
Iface.vlan_id = 100
Iface.vlan_priority = 0
Iface.iface_num = 100
Iface.mtu = 0
Iface.port = 0
#END Record
Setting the VLAN ID on the Ethernet Interface
If using RHEL5.X versions of Linux, it is recommended that you configure the
iSCSI VLAN on the Ethernet interface.
In RHEL6.3, and sles11sp3, it is not
necessary to set the VLAN on the Ethernet driver.
Execute the following commands to set the VLAN ID:
Vconfig add ethx <vlan number>
— Creates an L2 VLAN interface.
NOTE
Although not strictly required, QLogic recommends configuring the same
VLAN ID on the iface.iface_num field for iface file identification purposes.
