•
Online
: All paths are available.
•

Reduced
means that some paths might have an error status, in which case you
should check the status of individual paths and resolve the problem for any paths
that have an error status.
IO-Count
Total I/O count for the displayed paths, indicated by a decimal number. 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.
IO-Errors
Total I/O error count for the displayed paths, indicated by a decimal number. The
maximum value that can be displayed is 2

from 0.
PathID
The AutoPATH_ID indicated by a decimal number.
The AutoPATH_ID is assigned every time the host is restarted or when a path

restarted, AutoPATH_ID is assigned to each path of the LU when you execute the
cfgmgr
command.
