144 Command Line User Interface

-p <start | disable> Set the current state of the scrubbing policy <setting> can take any one of

the following values: start, disable.

-P {on|off|true|false} Controls whether the cache will perform a read ahead operation on the

LUNs being accessed, which may improve performance in some

environments. A value of on (true) will enable the read ahead operation.

A value of off (false) will disable it.

NOTE! This feature is disabled by default. Because of the way in which

the array stores data on the disks, this feature may decrease performance

in many environments. Before enabling this feature, contact HP support

for assistance.

-pd {1GB|2GB}

Set the port data rate to the value specified.

<FRULocation> identifies the host port for which the data rate is being set.

For example, to set the data rate for host port 1 on controller 2,

enter M/C2.H1.

NOTE! The disk port data rate cannot be changed on the VA 7410.

-pv <value> <FruLocation> Sets the paging value of the VFP Serial Port. This controls the number of

lines of output the VFP will generate before pausing and issuing a prompt

to hit a key and accept more output. If this value is set to zero, paging is

disabled and all output will be generated without breaks. This option is

useful when using terminals with smaller screen sizes.

<FruLocation> identifies the serial port and is of the form M/C1.VFP or

M/C2.VFP.
