-cp
or
cachepolicy
d, c Sets the cache policy for the virtual
disk. The valid arguments are:
d — (Direct I/O) Reads are not
buffered in cache memory.
c — (Cache I/O) All reads are buffered
in cache memory.
NOTE: This option is not supported
on the following controllers: CERC
SATA 1.5/6 CH, CERC SATA 1.5/2S,
and PERC 3/Di.
NOTE: The PERC 4/IM controller has a
fixed set of read, write, and cache
policies. If you set any of these policies
while creating a virtual disk, your
settings will be ignored.
The -cp option is optional and can
be added to the command line in
any order after the mandatory
option combination.
For SCSI controllers, the value of lun
should always be 0.
For SAS controllers, the value of
enclosure can be non-zero, in which
case you need to specify values for
channel, target, and enclosure.
