[E0:S0,E1,S1
,…] Specifies when one or more physical devices need to be specified in the
command line. Each [E:S] pair specifies one physical device, where E
means the 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 (Write Through)
is optional
.
If you enter WT at the command line, the application will use Write Through
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.
-Force 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.
