Binding iSCSI Target to Broadcom NX2 iSCSI Transport Name
By default, the open-iscsi daemon connects to discovered targets using
software initiator (transport name = 'tcp'). Users who wish to offload an
iSCSI connection onto CNIC device should explicitly change the transport
binding of the iSCSI node. This can be done using iscsiadm cli utility as
follows:
iscsiadm --mode node --targetname iqn.2004-
06.com.broadcom:tg1 \
--portal 192.168.1.100 --op=update \
--name=node.transport_name --
value=${XPORT_NAME}
where XPORT_NAME=bcm570x-xxyyzz
xx - pci bus number of the NX2 device
yy - pci device number of the NX2 device
zz - pci function number of the NX2 device
Network interface to iscsi transport name binding can be obtained by
executing the following.
dmesg | grep "bnx2i: netif"
Sample output in a system with two NetXtreme II devices:
bnx2i: netif=eth1, iscsi=bcm570x-050000
bnx2i: netif=eth0, iscsi=bcm570x-030000
If you wish to switch back to use the software initiator, enter the following:
iscsiadm --mode node --targetname iqn.2004-
06.com.broadcom:tg1 \
--portal 192.168.1.100 --op=update \
--name=node.transport_name --value=tcp
Making Connections to iSCSI Targets
Refer to open-iscsi documentation for a comprehensive list of iscsiadm
commands. This is a sample list of commands to discovery targets and to
create iscsi connections to a target.
