BIOS setting of SUT:
v Disable SpeedStep/Hyper-threading/C3/C6 in BIOS CPU configuration.
The test steps are seperated to
1.Install OFED,
2. ib IP setting
3.ssh key setting
4.run script
---------------------------------------------------------------------------
1.Install OFED
#cd OFED
#./install.sh
From the following menu select 2 “Install OFED Software”
InfiniBand OFED Distribution Software Installation Menu
1) View OFED Installation Guide
2) Install OFED Software
3) Show Installed Software
4) Configure IPoIB Network Interface and OpenSM Server
5) Uninstall InfiniBand Software
6) Build OFED Software RPMs
Q) Exit
Select Option [1-6]:
|
From the following sub-menu select 3 “All packages (all of openib, mpi)”
Select OFED Software
1) Basic (InfiniBand modules and basic user level libraries)
2) HPC (InfiniBand modules and libraries, mpi and diagnostic tools)
3) All packages (all of openib, mpi)
4) Customize
Q) Exit
Select Option [1-4]:
|
After selecting the complete installation you will be prompted for the compiler used for compiling the 2 MPI packages included in the distribution. Accept the default of gcc when prompted.
Install complete and successfully.
2. ib IP setting
#/etc/init.d/openibd start
#service opensmd start#chkconfig opensmd on
make sure state is Active in ibstat
#ibstat
Set ib ip address in SUT1
#ifconfig ib0 10.0.0.1 255.255.255.0
Set ib ip address in SUT2
#ifconfig ib0 10.0.0.2 255.255.255.0
Disable iptables on both SUT1 and SUT2
#service iptables stop
Check SUT1 and SUT2 connect
(SUT1)# ping 10.0.0.2
3.ssh key setting
From the host 10.0.0.1 perform the following steps:
#ssh 10.0.0.2 (ssh “ip”)
At the prompt similar to the following, type yes and press Enter.
----------------------------------------------------------------------------------------------------photo
The authenticity of host 'localhost (10.0.0.2)' can't be established.
RSA key fingerprint is 23:35:92:2b:df:5b:d6:1b:6a:32:24:ee:18:d2:82:18.
Are you sure you want to continue connecting (yes/no)?
-----------------------------------------------------------------------------------------------------
Enter root password then type exit.
Generate authentication keys
cd ~/.ssh
ssh-keygen –t rsa
Continue to press enter to accept default file name and no passphrase.
-----------------------------------------------------------------------------------------------------------photo
[root@localhost ~/.ssh]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
7a:e0:dc:a5:ec:99:0a:7a:33:4f:d6:ee:9d:5c:7d:c2 root@localhost
------------------------------------------------------------------------------------------------------------
Create the authorized_keys file for uutn1.
cat id_rsa.pub >> authorized_keys
Copy the authorized_keys file to the initiator host uutn1.
scp authorized_keys 10.0.0.2:~/.ssh/10.0.0.2.id
From the initiator host 10.0.0.2 perform the following steps.
cd ~/.ssh
cat 10.0.0.2.id >> authorized_keys
Re-do test, you have to clear the old key
Clear all existing auth-keys in SUT1 (unsvr) and SUT2 (unsvr1)
SUT1) # rm -rf ~/.ssh/*
SUT2) # rm -rf ~/.ssh/*
SUT1) # rm -rf ~/.ssh/*
SUT2) # rm -rf ~/.ssh/*
4.run script
