Teaming with Channel Bonding

Statistics

Linux iSCSI

Offload

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.

Detailed statistics and configuration information can be viewed using the ethtool utility. See the ethtool man page for more information.

This section describes how to install and run Linux iSCSI applications.

The following recommendations apply to offloading Linux iSCSI programs:

ˆNot all Broadcom NetXtreme II adapters support iSCSI offload.

ˆThe iSCSI session will not recover after a hot remove and hot plug.

ˆThe iSCSI driver/firmware will not offload iSCSI connections onto a jumbo frame-enabled CNIC device.

ˆFor 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.

ˆIn 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:

ˆ“Installing User Application - bnx2id” on page 66

ˆ“Installing Open iSCSI User Applications” on page 67

ˆ“Binding iSCSI Target to Broadcom NX2 iSCSI Transport Name” on page 68

ˆ“Making Connections to iSCSI Targets” on page 68

ˆ“Maximizing Offload iSCSI Connections” on page 69

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 52 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.
