Data Type


Default Value



This parameter specifies the number of volumes used for each stripe in the FMS file striping system. Use this parameter to create a large disk out of two or more smaller disk partitions.

For large files the amount of storage required per stripe may exceed the size of the disk partition. This parameter provides for binding multiple disk partitions together.

On some systems there is a 2 Gbyte address limitation for individual disk files. This option may be used to exceed that limitation.

When NUMVOL is greater than 1, FMS writes data to the first volume until MBYTES of data have been transferred. FMS then switches to the second volume. This process continues until the entire file has been written.

Only symmetric configurations are supported. All disk volumes must have the same capacity.
