Overview

iSCSI protocol

The HP iSCSI protocol transports block-level storage requests of TCP connections over IPv4 and IPv6. Using the iSCSI protocol, systems can connect to remote storage and use it as a physical disk although the remote storage provider or target may actually be providing virtual physical disks. HP Accelerated iSCSI supports all targets that are certified and supported by Linux software.

HP Gigabit Ethernet Multifunction Server Adapters can be enabled as iSCSI devices or virtual iSCSI host bus adapters (HBAs), a feature commonly referred to as accelerated iSCSI. iSCSI HBAs or accelerated adapters, provide the capability to run iSCSI protocol over offloaded TCP connections. By offloading the IPv4 or IPv6 TCP connection processing to an HP Gigabit Ethernet Multifunction Server Adapter, CPU utilization is reduced allowing additional processing capacity for applications. The HP accelerated iSCSI solution supports all targets that are certified and supported by Linux software.

Supported operating systems

• Red Hat Enterprise Linux 5 AS/ES for AMD64/EM64T

• Red Hat Enterprise Linux 5 AS/ES for x86

• SUSE LINUX Enterprise Server 10 (SP1, SP2) for x86

• SUSE LINUX Enterprise Server 10 (SP1, SP2) for AMD64

Installation and configuration

Downloading files

1. Go to the HP website (http://www.hp.com/#Support).

2. Select Download drivers and software (and firmware).

3. Type the adapter name in the For product box, and then click Go. For example, NC382T.

4. Select an operating system.

5. Click HP NC-Series iSCSI Offload Driver for Linux.

6. Click download and save the HP SoftPaq (sp#####.exe) file to a directory on your hard drive. The

SoftPaq file is a self-extracting executable with a file name based on the SoftPaq number.

7. Click the SoftPaq file to extract the files.

Installing the BRCM Multifunction drivers for Linux

The HP NC-Series Broadcom Multifunction Drivers for Linux are released in a source RPM format and the file name for the package is netxtreme2-<version>.sri.rpm. The package contains the source code and build instructions for bnx2, bnx2x, and cnic drivers.

1. Build Environment Setup. The netxtreme2 package requires the presence of packages that provide

the right build environment. These packages provide kernel headers, makefiles, and symbol files (suggested only on SLES distributions).

Red Hat installations: For each kernel flavor you want to build the driver make sure you have the associated kernel-devel

package. For example, kernel-2.6.18.92.el5 requires kernel-devel-2.6.18-92.el5 and kernel-PAE-

2.6.18.92.el5 requires kernel-PAE-devel-2.6.18-92.el5. SUSE SLES installations: Make sure that kernel-source and kernel-syms packages are installed. The kernel-syms package

contains symbol versions for all of the iterations that the distribution supports.

2. Install the source RPM package.

# rpm -ivh netxtreme2-<version>.src.rpm

3. Build the binary RPM for the netxtreme2.

Red Hat installations:

# cd /usr/src/redhat # rpmbuild -bb SPECS/netxtreme2.spec

SLES installations:

# cd /usr/src/packages # rpmbuild -bb SPECS/netxtreme2.spec

If you get an error during the build process, go back to step one above.

4. Check for the existence of a current version of the netxtreme2 package as follows:

# rpm -q netxtreme2
