Change Volume Serial Number Utility
Only DIGITIAL authorized service personnel may use this utility.
The Change Volume Serial Number (CHVSN) utility generates a new
volume serial number (called VSN) for the specified device and writes it
on the media. It is a way to eliminate duplicate volume serial numbers
and to rename duplicates with different volume serial numbers.
Device Statistics Utility
The Device Statistics (DSTAT) utility allows you to log I/O activity on
a controller over an extended period of time. Later, you can analyze that
log to determine where the bottlenecks are and how to tune the
controller for optimum performance.
