Preparing the DHCP Server in Linux
NOTE:
Prior to installing DHCP, make sure that QLogic OFED+ is already installed
on your DHCP server.
1. Download and install the latest DHCP server from www.isc.org.
Standard DHCP fields holding MAC address are not large enough to contain
an IPoIB hardware address. To overcome this problem, DHCP over
InfiniBand messages convey a client identifier field used to identify the
DHCP session. This client identifier field can be used to associate an IP
address with a client identifier value, such that the DHCP server will grant
the same IP address to any client that conveys this client identifier.
2. Unpack the latest downloaded DHCP server.
tar zxf dhcp-release.tar.gz
3. Uncomment the line /* #define USE_SOCKETS */ in
dhcp-release/includes/site.h
4. Change to the main directory.
cd dhcp-release
NOTE:
If there is an older version of DHCP installed, save it before continuing
with the following steps.
5. Configure the source.
./configure
6. When the configuration of DHCP is finished, build the DHCP server.
make
Configuring DHCP
7. When the DHCP has successfully finished building, install DHCP.
make install
1. From the client host, find the GUID of the Host Channel Adapter by using
p1info or look at the GUID label on the Infiniband adapter.
2. Turn the GUID into a MAC address and specify the port of the InfiniBand
adapter that is going to be used at the end, using b0 for port0 or b1 for
port1.
