You can mount a VxFS file system by using the mount command. When you enter the mount command, the generic mount command parses the arguments and the -F FSType option executes the mount command specific to that file system type. The mount command first searches the /etc/fs/FSType
directory, then the /usr/lib/fs/FSType
directory. If the -F option is not supplied, the command searches the file /etc/vfstab
for a file system and an FSType matching the special file or mount point provided. If no file system type is specified, mount uses the default file system.
