A command often requires a parameter, and some parameters require a value, but the specific parameters
and values that are valid for a given command depend on the target to which you apply the command.
To determine the valid parameters and values for a particular combination of target and command variables,
you can query the device. You can also inspect the example commands in other sections of this guide.
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 slot=0 ld 1 modify raid=0 ss=?
A typical screen response in this case could be:
Available options are:
8
16 (current value)
32
64
128
256 (default)
To determine which parameters can be queried, use the
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 slot=0 ld 1 delete forced
Under VMware ESXi 6.x, the forced flag is required for any command that has the option for a forced flag. If
the forced parameter is not used, the system generates an error message notifying the user that the
command could not be completed without this flag.
