Enabling and Disabling Quick I/O
If the Quick I/O feature is licensed and installed, Quick I/O is enabled by default when a file system is
mounted. Alternatively, the VxFS mount -o qio command enables Quick I/O. The mount -o noqio
command disables Quick I/O.
If Quick I/O is not installed or licensed, a file system mounts by default without Quick I/O and no error
message is displayed. However, if you specify the -o qio option, the mount command terminates without
mounting the file system.
