The following parameters are available for the disk flushing program (n refers to a numeric parameter in the range specified by the option description):
Verbose - issues constant status messages. | |
Specifies a path and file to log messages. If | |
| specified, messages are displayed on the line that started the |
| disk flushing program. |
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. |
Sleep time in milliseconds between the flushing of data | |
| sections. For example, parameter |
| seconds between data sections. The default is 1 sec; the |
| range is 0.25 to 15 sec. |
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. |
Sleep time in milliseconds between workspace slices. For | |
| example, parameter |
| between workspace sections. The default is 0.10 sec; the |
| range is 0.10 to 1 second. |
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
