Q
NOTE:
NOTE:
8. (Linux) "Show uname -a for all hosts" will 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.
If any hosts are identified with an incorrect OS version, the OS on those hosts should
be corrected at this time and operation of this sequence should be aborted when
prompted. As necessary all the preceding setup steps should then be repeated for
those hosts (there is no harm in repeating them for all the hosts).
9. (Host) "Install/Upgrade InfiniServ Software" will 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.
When prompted, select to do an initial installation as follows:
Would you like to do an upgrade install? [y]: n
Would you like to do an initial install/load? [n]: y
NOTE:
If any hosts fail to be installed, use the "View ibtest result files" option to review the
result files from the update. For more details, see "Interpreting the ibtest log files"
on page 5-68.
10. (Host) "Configure IPoIB IP Address" will create the ifcfg-ib1 files on each host.
The file will be created with a statically assigned IP address. The IPoIB IP
address for each host will be determined by the resolver (Linux host command).
If not found via the resolver, /etc/hosts on the given host will be checked.
11. (Host) "Build MPI Test Apps and Copy to Hosts" will build the MPI sample
benchmarks on the IB Management Node and copy the resulting object files to
all the hosts. This is in preparation for execution of MPI performance tests and
benchmarks in a later step.
12. (Linux) "Reboot Hosts" will reboot all the selected hosts and ensure they go
down and come back up (as verified via ping over the management network).
When the hosts come back up, they will be running the IB software installed.
13. (Linux) If there are any other setup operations which need to be performed on
all hosts, they may be performed using the "Run a command on all hosts" option.
D000006-000 Rev A
If DNS is being used, this step should be skipped.
Typically, /etc/resolv.conf is setup as part of OS installation for each host.
However, if /etc/resolv.conf was not setup on all the hosts during OS
installation, the Fast Fabric "Copy a file to all hosts" operation could be
done at this time to copy /etc/resolv.conf from the IB Management Node
to all the other nodes.
An initial installation will uninstall any existing InfiniServ software on the
selected hosts. An upgrade install is not appropriate at this step.
