You can specify the -Silent command line option for all possible functions of the
MegaCLI Configuration Utility. If you enter this option at the command line, no
message displays on the screen.
A second CLI utility, known as Pre-boot MegaCLI (PCLI), is available. You can enter this
utility during bootup. PCLI gives you an alternative way to access the CLI utility.
To access PCLI, while the host computer is booting, hold down the <Ctrl> key and press
the <Y> key when the following text appears on the screen:

Specifies the command is for virtual drives 0, 1, and 2. You can select two or
more virtual drives in this manner.
Specifies the command is for all virtual drives.
Specifies when one or more physical devices need(s) to be specified in the
command line. Each [E:S] pair specifies one physical device where E
means device ID of the enclosure in which a drive resides, and S means the
slot number of the enclosure.
In the case of a physical device directly connected to the SAS port on the
controller, with no enclosure involved, the format of [:S] can be used
where S means the port number on the controller. For devices attached
through the backplane, the firmware provides an enclosure device ID and
MegaCLI expects the user input in the format of [E:S]. In the following
sections, only the format, [E:S], is used in the command descriptions,
although both formats are valid.
Indicates that the parameter is optional except when it is used to specify
physical devices. For example, [WT] means the write policy (WriteThrough)
.
is optional
If you enter WT at the command line, the application will use WriteThrough
write policy for the virtual drive. Otherwise, it uses the default value for the
parameter.
Indicates that the parameters are grouped and that they must be given at
the same time.
Specifies that the MegaCLI utility does not ask you for confirmation
before it performs this command. You might lose data using this option
with some commands.
