Q
NOTE: It is recommended that SSH be used in place of the
check_rsh
command.
4.1.4
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
Copy /etc/hosts to all hosts
(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
Show uname -a for all hosts
(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
Install/Upgrade QuickSilver Software
(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.
