E.6.4 DHCP Configuration for iSCSI Boot with FlexBoot (PXE SAN Boot)
Modify the following host declaration in your DHCP configuration file to allow PXE SAN Boot
host sqa070 {
filename "";
option root-path "iscsi:12.7.6.30::::iqn.2013-10.qalab.com:sqa030.prt9";
fixed-address 12.7.60.70 ;
hardware ethernet 00:02:c9:32:e8:80 ;
}
E.7 SAN-Booting with FlexBoot in CHAP Environment
For Successful SAN-Booting with FlexBoot in CHAP environment, the FlexBoot in use must
support passing CHAP credentials. Please note that FlexBoot v3.4.149 does not support such
operation. Hence, use FlexBoot to chain-load an UNDI software which supports passing CHAP
credentials. This can be achieved by using the UNDI software module from iPXE.org, called
undionly.kpxe. A Linux host is required to create undionly.kpxe.
Step 1. Install the below prerequisite software to support necessary UNDI's compilation.
[root@sqa030 ~]# yum install -y gcc binutils make perl
Step 2. Download the UNDI sources from iPXE.org.
