Introduction
============
This file describes how to build and install the iSCSI driver
for network adapters mentioned in the PRODUCTS AFFECTED section.

User guides and additional HP Network Adapter information can be found at:
http://h18004.www1.hp.com/products/servers/networking/index-nic.html


Packaging
=========
The driver is released in Kernel Module Package (KMP) source RPM format.
KMP packages use macros that determine kernel flavors for which binary 
packages need to be built based on spec file rules.

It is important to have the right build environment set up in order to
compile a binary RPM from source package. See "Build Environment Setup"
section below.


Build Environment Setup
========================
This package requires the presence of certain other packages that provide
the right build environment to enable building a KMP binary rpm from the
source rpm. These packages provide kernel headers, makefiles and symbol
files. Please ensure that the following are installed:

RHEL installation:
	1. redhat-rpm-config package
	2. kernel-devel-<kernel_version> package
	3. kernel-<flavor>-devel-<kernel_version> package
	Eg: kernel-2.6.18.92.el5 requires kernel-devel-2.6.18-92.el5
	    kernel-PAE-2.6.18.92.el5 requires kernel-PAE-devel-2.6.18-92.el5

	See the "Caveats" section below for more details.

SLES Installation:
	1. kernel-source-<kernel_version> package
	2. kernel-syms-<kernel_version> package
	3. SLES11 requires kernel-<flavor>-devel-<kernel_version> package
	   in addition to the above two mentioned


Installing the RPM Package
=============================
1. This package requires a specific build environment. Please refer the
"Build Environment Setup" section above before proceeding.

2. Install the source RPM package.
   
	# rpm -ivh hp-be2iscsi-<version>.src.rpm

3. Build the binary RPM for the be2iscsi driver.

	RHEL 5:
	# rpmbuild -bb /usr/src/redhat/SPECS/hp-beiscsi.kmp.spec

	RHEL 6:
	# rpmbuild -bb ~/rpmbuild/SPECS/hp-beiscsi.kmp.spec

	SLES:
	# rpmbuild -bb /usr/src/packages/SPECS/hp-beiscsi.kmp.spec

	If you get an error during the build process, refer to the 
	"Build Environment Setup" section.

	NOTE: One can build binary RPM for a specfic kernel flavor as follows:

	# rpmbuild -bb SPECS/hp-beiscsi.kmp.spec --define "KVER <kver>"

	NOTE:  RHEL 5 x86 installations require the "--target" switch
	when building on Intel compatible machines. Please see the 
	"Caveats" section below for more details.

	# rpmbuild --target=i686 -bb /usr/src/redhat/SPECS/hp-beiscsi.kmp.spec

4. Check for the existence of a current version of the be2iscsi package as 
follows:
	
	RHEL
	# rpm -q kmod-hp-be2iscsi-<flavor> 

	SLES
	# rpm -q hp-be2iscsi-kmp-<flavor>

	If an old version of the package exists, the RPM package should be
	removed.

	RHEL
	# rpm -e kmod-hp-be2iscsi-<flavor>

	SLES
	# rpm -e hp-be2iscsi-kmp-<flavor>

	Verify if the old hp-be2iscsi package has been removed as follows:

	RHEL
	# rpm -q kmod-hp-be2iscsi-<kernel flavor>

	SLES
	# rpm -q hp-be2iscsi-kmp-<kernel flavor>  

5. If an older version of be2iscsi.ko is loaded into the kernel, remove
it as follows.

Note: If you are installing the package over network you may want to be
careful. It is not absolutely necessary to remove the modules. This step
is necessary if you are doing the upgrade on the physical console and
you intend to see the new drivers taking over immediately

	# lsmod | grep be2iscsi

Uninstall the existing active driver

	# modprobe -r be2iscsi

6. Install the new binary RPM package.

	RHEL 5
	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-be2iscsi-<flavor>-<version>.<arch>.rpm 

	RHEL 6
	# rpm -ivh \
	~/rpmbuild/RPMS/<arch>/kmod-hp-be2iscsi-<flavor>-<version>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/extra/hp-be2iscsi

	Note:  The "--nodeps" switch is required when installing to RHEL
	5.4 and RHEL 5.5. See the "Caveats" section below for more details.

	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-be2iscsi-<flavor>-<version>.<arch>.rpm --nodeps 

	SLES
	# rpm -ivh RPMS/<arch>/hp-be2iscsi-kmp-<version>-<flavor>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/updates/hp-be2iscsi

7.  Run "modinfo be2iscsi | grep version" and verify that the driver
version is latest

8.  Run "modprobe be2iscsi" to install latest "be2iscsi" driver module

9. Ensure that the /etc/modprobe.conf file is configured similar to the
example listed below.

	alias scsi_hostadpater1 be2iscsi

	For SLES, the configuration file is /etc/modprobe.conf.local

	Note: If the above entry does not exist, add it in the configuration
	file.

10. Reboot your server. Upon reboot the be2iscsi driver should be loaded.
Verify if the driver is loaded by executing the below command.

	# lsmod

You should find be2iscsi listed.


Uninstalling the RPM Package
=============================

The following command will uninstall the RPM.

	RHEL
	# rpm -e kmod-hp-be2iscsi-<kernel flavor>

	SLES
	# rpm -e hp-be2iscsi-kmp-<kernel flavor>

Caveats
========
1. The rpmbuild will fail the dependency check when building the non-base
(xen,pae,etc) kernel when the kernel-devel package is not installed.

Example:  If the OS only included the PAE kernel then the user would need to
install the kernel-pae-devel and kernel-devel packages.

2. The use of a "--target" switch is required so that rpmbuild does not try
to find an i386 kernel on the system.  If the "--target" switch is not used
then the build will fail with bizarre messages stating that specific kernel
packages are not installed on the machine yet these pacakges do not exist.

3. The rpmbuild will fail if the redhat-rpm-config package is not installed
because it cannot resolve the %kernel_module_package_buildreqs macro.  
The error will be similar to the following: 

error: line xx: Dependency tokens must begin with alpha-numeric,'_'or'/': 
BuildRequires: %kernel_module_package_buildreqs

4. RPM uses KMP packaging dependency data to ensure the dependencies are met
before installing the binary RPM.  Red Hat maintains a whitelist of kernel
symbols which RPM uses to validate against the KMP binaries.  Some symbols may 
be in the kernel but not on the whitelist which results in a failed binary RPM 
install. The user will need to use the "--nodeps" switch when installing the
binary. The be2iscsi packaged drivers uses the following symbols on 
RedHat EL5 Update 4 and Update 5 that are not on the whitelist:

ksym(pci_enable_msi) 
ksym(pci_disable_msi)
