Nearly all of the flexibility that is offered by the CLI is available through the
management GUI. However, the CLI does not provide the fix procedures that are
available in the management GUI. Therefore, use the fix procedures in the
management GUI to resolve the problems. Use the CLI when you require a
configuration setting that is unavailable in the management GUI.
You might also find it useful to create command scripts by using the CLI
commands to monitor for certain conditions or to automate configuration changes
that you make on a regular basis.

USB flash drive and Initialization tool interface
Use a USB flash drive to initialize a system and also to help service the node
canisters in a control enclosure.
The initialization tool is a Windows application. Use the initialization tool to set up
the USB flash drive to perform the most common tasks.
When a USB flash drive is inserted into one of the USB ports on a node canister in
a control enclosure, the software searches for a control file on the USB flash drive
and runs the command that is specified in the file. When the command completes,
the command results and node status information are written to the USB flash
drive.
When to use the USB flash drive
