Chapter 5: Installing the Linux Drivers

Teaming with
Channel Bonding
With the Linux drivers, you can team adapters together using the bonding
kernel module and a channel bonding interface. For more information, see
the Channel Bonding information in your operating system documentation.
Statistics
Detailed statistics and configuration information can be viewed using the
ethtool utility. See the ethtool man page for more information.
Linux iSCSI
Offload
This section describes how to install and run Linux iSCSI applications.
The following recommendations apply to offloading Linux iSCSI programs:
 Not all Broadcom NetXtreme II adapters support iSCSI offload.
 The iSCSI session will not recover after a hot remove and hot plug.
 The iSCSI driver/firmware will not offload iSCSI connections onto a
jumbo frame-enabled CNIC device.
 For MPIO to work properly, iSCSI nopout should be enabled on each
iSCSI session. Refer to open-iscsi documentation for procedures on
setting up noop_out_interval and noop_out_timeout values.
 In the scenario where multiple CNIC devices are in the system and the
system is booted via Broadcom's iSCSI boot solution, ensure that the
iscsi node under /etc/iscsi/nodes for the boot target is bound to the
NIC that is used for booting.
See the following sections:
 “Installing User Application - bnx2id” on page 68
 “Installing Open iSCSI User Applications” on page 69
 “Binding iSCSI Target to Broadcom NX2 iSCSI Transport Name” on
page 70
 “Making Connections to iSCSI Targets” on page 70
 “Maximizing Offload iSCSI Connections” on page 71
Installing User Application - bnx2id
The bnx2id application should be installed under /sbin when bnx2i RPM
package is installed. See “Installing the Source RPM Package” on
page 54 for information. Run the bnx2id daemon before attempting to
create iSCSI connections. The driver does not establish connections to
the iSCSI target without the daemon's assistance.
bnx2id
The bnx2id daemon requires mknod and sh shell, which are standard on
any regular server. For iSCSI boot using NetXtreme II offload support,
binaries for mknod and sh need to be bundled into initrd image.
