(CP00xxxx.scexe), complete the following steps: 
1.  Go to the HP website at  http://www.hp.com
. 
2.  Click Software & Driver Downloads. 
3.  Enter the product name (for example, NC373i ) in the product box and begin the search.

Updating iSCSI option ROM 
HP NC-Series Broadcom Online Fi rmware Upgrade Utility  for Linux must be used on the system 
that needs the iSCSI boot option ROM to be u pdated from a Linux opertaing system or a Linux 
opertaing system live CD. 
To update to latest iSCSI boot option RO M image, complete the following steps: 
1.  The firmware utility requires the adapter interface to be up and running. Bring up a network 
adapter interface using the following command: 
# ifup ethx 
Or 
# ifconfig ethx up 
2.  Update the firmware usin g the following command: 
#./CPXXXXXX.scexe 
The upgrade installation activity  is written to a common installation log file called ./nicfwupg.log. 
 
 
Setting up iSCSI boot LUN 
ev  utility present in the HP ProLiant iSCSI Boot Package for Linux can be downloaded from the 
software download page of  HP ProLiant iSCSI Boot Package for Linux
. 
 
1.  Create the configuration file  evinput.txt. A sample configuration file is shown below. 
 
Following is a sample configuration file.

2.  Write the boot path to the target server. The boot path configuration file may be written to the 
target server with the ev DOS utility or written using the ibootcfg utility.  
a.  To write the boot path using the ev DOS util ity, boot to DOS and change directories 
to the ev DOS utility. The ev DOS utility is  packaged with the HP iSCSI boot feature. 
b.   Execute the following on the server with the option ROM.

							Installing the operating systems 
Root partition on SAN has become popular with blade systems and virtualization technologies. 
Multipath feature support for operat ing system installation partitions was introduced with the latest 
operating system distributions. OS vendors have provided the feature for enabling high 
availability for the installa tion partitions on the SAN. 
 
To enable the high availability feature in RHEL  and SLES operating system, complete the following 
steps: 
 
Enabling the Device Ma pper multipath feature 
Recommended configuration on  RHEL operating system 
 
Ensure that there are multiple paths to the LUNS befo re starting the installation process. If there is 
only one path to the LUNS, Anaconda installs the operating system on the SCSI device even if 
mpath is specified as a kernel parameter. Enabling  multipath features for the installation partitions 
on iSCSI SAN devices is supported in RHEL 5.3 and later. 
 
1.  Start the installation of the operating system. 
2.  Provide the parameter “linux mpath” to the kernel boot line. 
 
Figure 27 
 
3.  To add the iSCSI devices to the installation,  complete the following steps, else go to Step 4
: 
a.   Click  Advanced storage configuration .  
						

							 
Figure 28 
 
b.   Select Add iSCSI targets and click  Add drive. 
 
Figure 29 
 
c.   Enable network Interface for the currently used NIC.  
						

							 
Figure 30 
 
d.   Enter the target IP address. 
 
Figure 31 
 
e.   Repeat step a to d to add more iSCSI targets. 
 
4.  While creating partitions during the installation process, you will see multipath devices 
(/dev/mapper/mpath*). Create the installation partitions using multipath devices. 
Multipathing feature will be enabled for all  the operating system partitions created on 
multipath device during installation.
