v When you cannot connect to a node canister in a control enclosure using the
service assistant and you want to see the status of the node.
v When you do not know, or cannot use, the service IP address for the node

v When you have forgotten the superuser password and must reset the password.
Using a USB flash drive
Use any USB flash drive that is formatted with a FAT32 file system on its first
partition.
About this task
When a USB flash drive is plugged into a node canister, the node canister code
searches for a text file named satask.txt in the root directory. If the code finds the
file, it attempts to run a command that is specified in the file. When the command
completes, a file called satask_result.html is written to the root directory of the
USB flash drive. If this file does not exist, it is created. If it exists, the data is
inserted at the start of the file. The file contains the details and results of the
command that was run and the status and the configuration information from the
node canister. The status and configuration information matches the detail that is
shown on the service assistant home page panels.
The satask.txt file can be created on any workstation by using a text editor. If a
Microsoft Windows workstation is being used, the initialization tool can be used to
create the commands that are most often used.
The fault light-emitting diode (LED) on the node canister flashes when the USB
service action is being performed. When the fault LED stops flashing, it is safe to
remove the USB flash drive.
Results
The USB flash drive can then be plugged into a workstation and the
satask_result.html file viewed in a web browser.
To protect from accidentally running the same command again, the satask.txt file
is deleted after it has been read.
If no satask.txt file is found on the USB flash drive, the result file is still created,
if necessary, and the status and configuration data is written to it.
Using the initialization tool
The initialization tool is a graphical user interface (GUI) wizard that creates the
initial configuration on the control enclosure.
Before you begin
Access the initialization tool through a USB flash drive.
Verify that you are using a supported operating system. The initialization tool is
valid for the following operating systems:
v Microsoft Windows 8.1 (64-bit), or Microsoft Windows 7 (64-bit)
