Setup Password-less SSH/SCP

(Linux) This will run the setup_ssh -i "" command. This will setup secure

password-less SSH such that the IB Management Node can securely login to all

the other hosts as root via the management network without requiring a password.

Password-less SSH is required by Fast Fabric, MPI test applications and most

versions of MPI (including QuickSilver MPI).

4.1.5

(Linux) This will run the scpall /etc/hosts /etc/hosts command to copy the /etc/hosts

file on this host to all the other selected hosts. This is not necessary when using a

DNS server to resolve hostnames for the cluster.

4.1.6

(Linux) This run the cmdall "uname -a" command to show the OS version on

all the hosts. Review the results carefully to verify all the hosts have the expected

OS version. In typical clusters all hosts will be running the same OS and kernel

version.

4.1.7

(Host) This will run the ibtest load or ibtest update command to install the

IB software on all the hosts. By default it will look in the current directory for the

$FF_PRODUCT.<VERSION>.tgz file. If it is not found in the current directory, it

will prompt for input of a directory name where this file can be found.

Prompts will guide the user through options:

upgrade - updates all servers with new release. Only components previously

❥

installed are upgraded. Will fail for any hosts which have no InfiniServ IB software

installed

initial install/load - uninstalls any existing InfiniServ IB software and installs the

❥

given release based on fastfabric.conf installation options specified.

After the install is completed, the hosts will still need to be rebooted to bring up the

new IB drivers. This can be performed using the "Reboot Hosts" menu item

discussed below.

D000006-000 Rev A
