The <command> variable
The
<command>
variable can be any of the following words or phrases, corresponding to typical
configuration tasks:
add
create
delete
modify
remove
set target
There are also four nonconfiguration commands:
diag
("
Generating a diagnostic report
" on page
61
)
help
("
The help command
" on page
59
)
rescan
("
Rescanning the system
" on page
61
)
show
("
The show command
" on page
57
)
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 ("
Querying a device
" on page
56
). 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 ch="Lab4" 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 (default)
256
To determine which parameters can be queried, use the help feature of the CLI ("
The help command
" on
page
59
).
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
