View Stripeset Information
To see the contents of a stripeset, run mpdump.exe with no options from
the Command Prompt. The command is in the directory Program
Files\Hewlett-Packard\HP Clustered File System\bin on the drive where
you installed HP Clustered File System. Following is some sample
output.
Current Product MP Version: 2

The volume information appears near the end of the output, in the section
labeled “Membership Partition Volume Database.” The information
includes the stripe size and the subdevices making up each stripeset.
Extend a Dynamic Volume
The Extend Volume option allows you to add subdevices to an existing
dynamic volume. When you extend the volume on which a filesystem is
mounted, you can optionally increase the size of the filesystem to fill the
size of the volume.
NOTE: The subdevices used for a striped dynamic volume are called a
stripeset. When a striped dynamic volume is extended, the new
subdevices form another stripeset. The original stripeset is filled
first; then the new stripeset is filled. If you want the entire
dynamic volume to be in the same stripeset, you will need to
recreate the volume.
