Cluster (system) command-line interface
Use the command-line interface (CLI) to manage a clustered system 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 Information Center.
When to use the cluster (system) CLI
The cluster (system) CLI is intended for use by advanced users who are confident
at using a command-line interface.
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 using the CLI commands
to monitor for certain conditions or to automate configuration changes that you
make on a regular basis.
Accessing the cluster (system) CLI
Follow the steps that are described in the “Command-line interface” topic in the
“Reference” section of the Storwize V7000 Information Center to initialize and use
a CLI session.
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 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 Information Center to initialize and use
a CLI session.
USB key and Initialization tool interface
Use a USB key to initialize a system and also to help service the node canisters in
a control enclosure.
