Introduction 9
Some commands require that a parameter be specified, for example, the add user command. The required
parameter is the user name (add user jake), and if the username is not provided, an error message
displays indicating that a required parameter is missing.
Options
Options enable users to control certain behavior characteristics available during the command execution.
Some examples of options include controlling output format and specifying a quiet mode to suppress
interactive prompts.
Distinguish options from other command line elements by using a preceding hyphen (-). Option arguments
are required or optional, depending on the option being specified. For example, the -output option
requires an argument, which is a list of one or more output format attributes. However, the -quiet option
does not require any arguments to be specified.
The general format of a CLI option is as follows:
-[=argument1>,, . . .]
Example: ->show user suzi -output=script1
In the example, -output is the option, and script1 is an option argument.
Properties
Properties are specific configuration attributes of a managed element. Properties are commonly used during
set operations or add operations where a managed element is being modified or created. In some limited
circumstances, properties might also be used as a part of a show or other command.
IMPORTANT: If a property value contains embedded spaces, then the entire property value must
be contained within single or double quotes. Likewise, if a double quote is part of a property
value, it should be contained within single quotes, and if a single quote is part of a property value,
it should be contained within double quotes.
Command batching
Scripts are useful for batching many CLI commands. You can create a single CLI script to configure an entire
VC domain from scratch and use it on multiple enclosures.
When using a Linux SSH client, simply redirect the script into SSH. If the SSH keys are not configured on the
client and in the firmware, a password prompt appears. To enable script automation and better security, SSH
public/private key-pairs can be generated and uploaded to the public key to the VC firmware. For example:
>ssh [email protected] < myscript.txt
When using a Windows-based SSH client, pass the file to the client using the -m option. If the SSH keys are
not configured on the client and in the firmware, a password prompt appears. To allow script automation
and better security, SSH public/private key-pairs can be generated and uploaded to the public key to the VC
firmware. For example:
>plink [email protected] -m myscript.txt
The CLI enables you to enter multiple CLI commands in a single command-line invocation. This capability is
useful when batching several commands together and executing them in a particular sequence, within the
context of the same SSH session. This method improves the overall performance of lengthy script processing.
