Command Line Interface (CLI)
118 Modular SAN Array 1000 User Guide
CLI Overview
After accessing the interface, enter a command string at the CLI prompt (CLI>).
Commands must use a specific, preset syntax. After a declarative command is
entered and executed, the results are displayed at the CLI prompt.
When using the CLI, the following keystrokes have special meaning:
Note: The CLI uses a zero-based numbering system. For example, LUN number
assignments begin with 0.
When the MSA1000 has two controllers, the same firmware image is run on both
controllers. The two controllers communicate with each other through a PCI bus
called the inter-controller link (ICL). Each controller has a serial port and has a
CLI available to the users who connect the serial port to a serial terminal.
Some CLI commands are entered from one controller’s CLI prompt but are for the
other controller to execute. Command syntax instructs the controller to accept
user input, pass the command to the other controller, and then display the result.
The following keywords are used in the CLI to indicate a specific controller:
■ this_controller—is included in a command syntax to refer to the
controller that the CLI is connected to.
■ other_controller—is included in a command syntax to refer to the other
controller in the MSA1000.
