Reset Controller
This command resets a controller, and it is disruptive to I/O operations.
Important: When you reset a controller, the controller is removed from the data path and is not available
for I/O operations until the reset operation is complete. If a host is using logical drives that are owned
by the controller being reset, the I/O directed to the controller is rejected. Before resetting the controller,
either make sure that the logical drives that are owned by the controller are not in use or make sure that
a multi-path driver is installed on all of the hosts that use these logical drives.
