7.5 Task 3: Install Additional RPMs
Determine if you have to install additional software before installing the HP XC System Software:
• InfiniBand interconnect
The OpenFabrics Enterprise Distribution (OFED) software stack is included in RHEL4 U4,
and thus, the OpenIB service starts by default on the head node. OpenIB has not been
qualified, and you must install the Voltaire InfiniBand RPMs after you install the Red Hat
Enterprise Linux.
Follow this procedure to install the ibhost-biz-*.rpm before installing the HP XC System
Software. This rpm is provided by the vendor.
NOTE: You must obtain an updated InfiniBand driver from HP Support each time you
update the kernel.
1. Install the InfiniBand interconnect software using the instructions provided by the
vendor documentation.
2. Do the following to ensure that the OpenIB service does not start on the head node:
a. Stop the openib service:
# service openibd stop
b. Prevent the openib service from starting up at boot time:
