The following parameters are available for the disk flushing program (n

refers to a numeric parameter in the range specified by the option

description):

-v Verbose - issues constant status messages.

-f Specifies a path and file to log messages. If -f is not

specified, messages are displayed on the line that started the

disk flushing program.

-dn Number of data sections. The data space is divided into a

number of actual sections (represented by the numeric

parameter) spread across all drives. The default value is 60;

the range is 15 to 300.

-sn Sleep time in milliseconds between the flushing of data

sections. For example, parameter -s2000 would sleep 2

seconds between data sections. The default is 1 sec; the

range is 0.25 to 15 sec.

-wn Number of workspace sections. Within the workspace, each

level 0 drive is divided into a number of sections represented

by the numeric parameter. This yields a x b (where

represents the number of workspace sections and

represents the number of primary drives). The default is 10;

the range is 5 to 50.

-tn Sleep time in milliseconds between workspace slices. For

example, parameter -t100 would sleep 100 milliseconds

between workspace sections. The default is 0.10 sec; the

range is 0.10 to 1 second.

-ln Number of loops through data space before a full flush. The

default is 15; the range is 0 to 300. Zero suppresses the full

flush.

NOTE: The approximate data flushing time is given by d

x s (where d is

the number of data slices and s is the sleep time between data

slices). The approximate work flushing time is given by

x t x p drives (where w represents the number of workspace

sections,

t represents the sleep time between flushing workspace

sections, and

p represents the number of primary drives).

To increase the ability to control redundant workspace flushing, a new

parameter has been added to the config.ovf file in the mvEnterprise

home directory. This file overrides the default values for the sizes of the
