Summary

IO-Count
#1 - Total I/O count for a path. The maximum value that
can be displayed is 2
32 - 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 .
IO-Errors
#1 - Total I/O error count for a path. The maximum value
that can be displayed is 2
32 - 1 (4294967295). If the
total I/O error count reaches the maximum value, it
is reset, and the count is re-started from 0.
To reset the IO-Errors value to 0, execute the
dlnkmgr command's clear operation. Executing the
clear operation also clears the number of I/O
operations (IO-Count) to 0.
For details about the clear operation, see
