Legend:
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 on the
clear
operation, see 6.2 clear (Returns the Path Statistics to the Initial
Value).
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 on the
clear
operation, see 6.2 clear (Returns the Path
Statistics to the Initial Value).
DNum
#1 -- A hyphen (-) is displayed.
IEP
#1 -- The displayed paths are assumed to be in an intermittent error status
and checked whether those paths are to be operated for automatic
failbacks.
One of the following values is displayed for each path:
•
-
: Indicates that intermittent error monitoring is disabled or the
monitoring time for an intermittent error is out of range.
• A value of at least 0: Indicates the number of errors that occurred
during intermittent error monitoring.
•
*
: Indicates that an intermittent error occurred (automatic failback
does not check the path).
Physical
Device
#1
-- SCSI device configuration information. The names of the physical
device files under the
/devices
directory are displayed.
--
Paths
Total number of the paths recognized by HDLM for the LU to be
displayed.
--
OnlinePaths
Number of online paths among the paths recognized by HDLM for the
LU. When the value of
Paths
is equal to the value of
OnlinePaths
,
all paths are online. If the value of
OnlinePaths
is less than that of
Paths
, some paths might have an error status, in which case you
should check the status of individual paths and take resolve the
problem for any paths that have an error status.
