Section 5
Detailed Descriptions of Command LineTools
Some of the commands are only applicable when Linux is being used. They will
be marked with
(Linux) . Similarly some of the commands are only applicable when
QuickSlver Linux IB software is being used on the hosts. Those will be marked with
(Host) . All commands which are applicable only when SilverStorm IB Switches or
IB Chassis are being used will be marked with (Switch) . All remaining commands
are generally applicable to all environments and will be marked with (All) .
NOTE: Some of the Linux commands may be applicable to other Unix-like
operating systems if it is desired to enable use of non-IB specific Fast
Fabric tools (such as
cmdall
) against the given hosts.
The Fast Fabric tools are installed in directories which are part of the standard Linux
root PATH. Most of the tools are installed in
/sbin
.
5.1
Common Tool Options
There are some common options to the assorted command line tools. These options
are applicable to most of the tools:
5.1.1
-?
Will display Usage information for any of the commands (as will any invalid option)
5.1.2
-p
Runs the operation/command in parallel. This means the operation is performed
simultaneously on batches of 20 hosts. As such this option allows the overall
time of an operation to be much lower. However, a side effect is that any output
from the command will be bursty and intermingled. Therefore this option should
be used for commands where there is no output or the output is of limited interest.
For some commands (such as
scpall
), this will perform the operation in a quiet
mode to limit output. If the user wants to change the number of parallel operations
export
TEST_MAX_PARALLEL=#
where
#
is the new number (such as 30).
For more advanced operations (such as
ibtest
), parallel operation is the default
mode.
Parallel operation can also be disabled by setting
FF_MAX_PARALLEL
to
1
.
