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 -fis 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 -s2000would 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 a
	represents the number of workspace sections and b
	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 -t100would 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

w 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
