A.3.3. Install Mellanox OFED package and set network IPs
1. Install Mellanox OFED 1.5.3-3.0.0 if using InfiniBand (MLNX_OFED_LINUX-1.5.3-3.0.0-rhel6.1-
x86_64.iso).
Note: If 10GbE network is deployed, please skip this step.
You may need to install the dependencies:
glibc-devel-2.12-1.25.el6.i686.rpm
tcl-8.5.7-6.el6.x86_64.rpm
tk-8.5.7-5.el6.x86_64.rpm
2. Configure the IPoIB ib0 address or 10GbE address for the public network as per the specification in
Section A.1.1.
3. Set the IP addresses on the private network interface, public network interface and iDRAC NIC on
each server according to the NSS-HA cluster specification in section A.1.1
Make sure that /etc/hosts on both servers to contain the entries below for both servers
# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
15.15.10.1 active.hpc.com active
15.15.10.2 passive.hpc.com passive
On both servers, disable NetworkManager service. HA cluster requires the NetworkManager
service to be off.
# service NetworkManager stop
# chkconfig NetworkManager off
4. Set up password-less ssh between the active and passive servers.
active# ssh-keygen -t rsa
active# chmod 700 ~/.ssh
active# ssh-copy-id –i ~/.ssh/id_rsa.pub passive
passive# ssh-keygen -t rsa
passive# chmod 700 ~/.ssh
passive# ssh-copy-id –i ~/.ssh/id_rsa.pub active
