3 – Getting Started
Installing InfiniBand on the Remaining Servers
When placed in the editor for hosts, create the file with a list of the hosts names
(the TCP/IP management network names) except the IB Management node from
which Fast Fabric is presently being run, one entry per line. Such as:
host1
host2
NOTE:
If multiple IB Management Nodes are to be used, they may be listed at this time
and Fast Fabric can aid in their initial installation and verification.
For further details about the file format, refer to the section "Selection of Hosts" on
page 5-3.
4. (All) "Verify Hosts via Ethernet ping" will ping each selected host over the
management network. If all hosts were found, continue to the next step. If
some hosts were not found, abort out of the menu and review the following for
those hosts which were not found:
Is host powered on and booted
❥
Is host connected to management network
❥
Is host management network IP address and network settings consistent with
❥
DNS or /etc/hosts
Is Management node connected to the management network
❥
Are Management node IP address and network settings correct
❥
Is the management network itself up (switches, routers, etc)
❥
Is correct set of hosts listed in the hosts file (the previous step may be repeated
❥
to review and edit the file as needed)
5. (Linux) "Verify rsh/rcp Configured" will confirm that passwordless rsh/rcp is
properly configured such that the IB Management Node can access all the other
hosts.
NOTE:
6. (Linux) "Setup Password-less ssh/scp" 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).
7. (Linux) "Copy /etc/hosts to all hosts" will copy the /etc/hosts file on this host to
all the other selected hosts.
3-14
Do not list the IB Management Node itself (i.e., the node where Fast
Fabric is currently running).
It is recommended that ssh be used instead in which case this step may
be skipped
