Hiding warning prompts

When you enter a command for an operation that can potentially destroy user data, the CLI displays a

warning and prompts you for input (a y or an n) before continuing the operation. This situation is

undesirable when running batch file scripts. To prevent warning prompts from being displayed, use the

term forced as a parameter.

Example command:

ctrl ch="Lab4" ld 1 delete forced

Querying a device

If you do not know what values a parameter can have, you can sometimes query the device to find out by

entering a ? as the value of the parameter.

Example command:

=> ctrl ch="Lab4" ld 1 modify raid = 0 ss=?

A typical screen response in this case could be:

Available options are:

16 (current value)

128 (default)

256

For information about which parameters can be queried, refer to the CLI help ("Help" on page 45).

Help

To get help with the CLI, enter help at the CLI prompt as follows:

=> help

This command does not need a target variable or a parameter.
