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.

Adding static entry

iscsiadm -m node -p <ipaddr[:port]> -T iqn.2007- 05.com.broadcom:target1 -o new
