- 1 (4294967295). If the
total I/O count reaches the maximum value, it is
reset, and the count is re-started from 0.
To reset the IO-Count value to 0, execute the
dlnkmgr command's clear operation. Executing the
clear operation also resets the number of I/O errors
(IO-Errors) to 0. For details about the clear
operation, see
clear (Returns the Path Statistics to
the Initial Value) on page 6-3.
