For the Thunder 9200/9500V Series, Lightning 9900/9900V Series
TagmaStore, and Universal Storage Platform V:
Attribute of the path
Own
: Owner path
Non
: Non-owner path
When connected to the Lightning 9900 Series, Lightning 9900V Series,
TagmaStore USP, or Universal Storage Platform V, all paths are owner paths.
For the EMC DMX series, EMC CX series, and HP EVA series:
A hyphen (-) is displayed.
IO-Count
3
Not
displayed
Total I/O count for the path, 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.
To reset the
IO-Count
value to zero, execute the
dlnkmgr
command's
clear
operation. Executing the
clear
operation also resets the number of I/O errors
(
IO-Errors
) to zero. For details about the
clear
operation, see section 7.2.
IO-Errors
3
Not
displayed
Total I/O error count for the path, indicated by a decimal number. 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 zero, execute the
dlnkmgr
command's
clear
operation. Executing the
clear
operation also clears the number of I/O
operations (
IO-Count
) to zero.
For details about the
clear
operation, see section 7.2.

is displayed as Dev indicating the entire LU.
IEP

Not
displayed
The displayed paths are assumed to be in an intermittent error status and checked
whether those paths are to be operated for automatic failback.
One of the following values is displayed for each path:
An
-
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.
An
*
: Indicates that an intermittent error occurred (automatic failback does not
check the path).
Not displayed
Paths
Total number of the paths recognized by HDLM for the LU to be displayed,
indicated by a decimal number
Not displayed
OnlinePaths
Number of available paths among the paths recognized by HDLM for the LU to be
displayed, indicated by a decimal number. 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 may have an error status, in which case you
should check the status of individual paths and take appropriate action for any
paths that have an error status.
