D000006-000 Rev A 5-1Section 5Detailed Descriptions of Command LineToolsSome of the commands are only applicable when Linux is being used. They willbe marked with (Linux). Similarly some of the commands are only applicable whenQuickSlver 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 orIB Chassis are being used will be marked with (Switch). All remaining commandsare generally applicable to all environments and will be marked with (All).NOTE: Some of the Linux commands may be applicable to other Unix-likeoperating systems if it is desired to enable use of non-IB specific FastFabric tools (such as cmdall) against the given hosts.The Fast Fabric tools are installed in directories which are part of the standard Linuxroot PATH. Most of the tools are installed in /sbin.5.1Common Tool OptionsThere are some common options to the assorted command line tools. These optionsare 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-pRuns the operation/command in parallel. This means the operation is performedsimultaneously on batches of 20 hosts. As such this option allows the overalltime of an operation to be much lower. However, a side effect is that any outputfrom the command will be bursty and intermingled. Therefore this option shouldbe 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 quietmode to limit output. If the user wants to change the number of parallel operationsexport TEST_MAX_PARALLEL=# where # is the new number (such as 30).For more advanced operations (such as ibtest), parallel operation is the defaultmode.Parallel operation can also be disabled by setting FF_MAX_PARALLEL to 1.
