User Application - brcm_iscsiuio
Run the brcm_iscsiuio daemon before attempting to create iSCSI connections. The driver will not be able to establish
connections to the iSCSI target without the daemon's assistance.

Open iSCSI User Applications
Install and run the open-iscsi programs, iscsid and iscsiadm, from the Broadcom distributed open-iscsi packages. Refer to
Packaging for details. All pre-installed open-iscsi packages need to be removed before the Broadcom iSCSI-supported
packages can be installed.
1. Remove all existing open-iscsi packages.
RHEL5
rpm -e iscsi-initiator-utils
2. Install the source RPM package.
rpm -ivh <open-iscsi-package-name>.src.rpm
3. CD to the RPM path and build the binary driver for your kernel.
cd /usr/src/{redhat,OpenLinux,turbo,packages,rpm ..}
or
rpmbuild -bb SPECS/<open-iscsi-package-name>.spec (for RPM version 4.x.x)
Note that the RPM path is different for different Linux distributions.
4. Install the newly built package.
rpm -ivh RPMS/<arch>/<open-iscsi-package-name>.<arch>.rpm
where <arch> is the machine architecture such as i386.
rpm -ivh RPMS/i386/<open-iscsi-package-name>.i386.rpm
5. Start the daemon.
iscsid
Bind 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 iSCSI connection onto CNIC device should explicitly change 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=iface_file_name
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 = <name of the iface file>
iface.hwaddress = XX:XX:XX:XX:XX:XX
iface.ipaddress = XX:XX:XX:XX
