Service command-line interface

Use the service command-line interface (CLI) to manage a node canister in a
control enclosure using the task commands and information commands.
For a full description of the commands and how to start an SSH command-line
session, see the "Command-line interface" topic in the "Reference" section of the
Storwize V7000 Unified Information Center.
When to use the service CLI
The service CLI is intended for use by advanced users who are confident at using
a command-line interface.
To access a node canister directly, it is normally easier to use the service assistant
with its graphical interface and extensive help facilities.

Accessing the service CLI

Follow the steps that are described in the "Command-line interface" topic in the
"Reference" section of the Storwize V7000 Unified Information Center to initialize
and use a CLI session.

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 node canister 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
The USB flash drive is normally used to initialize the configuration after installing
a new system.
Using the USB flash drive is required in the following situations:
v When you cannot connect to a nodecanister in a control enclosure using the
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
