Summary
displayed
However, a hyphen (-) is displayed when an
algorithm other than the following is used:
• exrr: The Extended Round Robin algorithm
• exlio: The Extended Least I/Os algorithm
• exlbk: The Extended Least Blocks algorithm
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
clear (Returns the Path
Statistics to the Initial Value) on page 6-3.
DNum
#1
-
When Dev indicates an entire LU, 0 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 path status is
Offline(C).
• 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).
LB
#1
-
The algorithm being used for load balancing.
• exrr: The Extended Round Robin algorithm
• exlio: The Extended Least I/Os algorithm
• exlbk: The Extended Least Blocks algorithm
• vmwfixed: The Fixed algorithm (VMware)
• vmwmru: The Most Recently Used algorithm
(VMware)
• vmwrr: The Round Robin algorithm
(VMware)
• unknown: An algorithm other than the above
VmPSP
#1
-
The PSP currently in effect.
