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
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 -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
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
