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

In previous versions of the CLI, the user had the following options to enable different CLI command

invocations:

Interactively input commands at the shell after logging in via SSH. This method works well for
interactive users, but not necessarily for automation. Although users could write expect scripts for

command processing, the solution is not optimal.

Enter remote shell script commands, one-at-a-time, using a remote SSH client. This method enhances

automation, but performance is lessened because each command requires logging in and logging
out of the remote SSH server in the firmware. Because the authentication and command processing is

performed over an encrypted channel, users experience a performance hit. If the user script is

performing many operations in the client script, the time necessary to perform the tasks increases.

The updated version of the CLI supports a new enhancement that enables users to enter multiple CLI
commands in a single command-line invocation. This capability is useful in situations where users prefer to

batch several commands together and execute them in a particular sequence, within the context of the

same user login SSH session. This method improves the overall performance of lengthy script processing.
Example 1: Sample commands with no command batching
add profile Profile1
add network Network1
add uplinkset UplinkSet1
Example 2: Sample commands using command batching
add profile Profile1;add network Network1;add uplinkset UplinkSet1

Supporting comments and blank lines in CLI scripts

Scripts are useful for batching many CLI commands. Administrators can create a single CLI script to
configure an entire VC domain from scratch and use it on multiple enclosures.
The updated version of the CLI supports command scripts that contain blank lines and comments. In

previous firmware versions, all commands that were provided as input to the CLI through scripts could
