As soon as a volume has been created and initialized, it is available for use as a virtual disk partition by the operating system for the creation of a file system, or by application programs such as relational databases and other data management software.
Creating a volume in a disk group sets up block and character (raw) device files that can be used to access the volume:
/volume block device file for volume
/volume character device file for volume
The pathnames include a directory named for the disk group. Use the appropriate device node to create, mount and repair file systems, and to lay out databases that require raw partitions.
