Summary
displayed
Paths
Total number of displayed paths, indicated by a decimal (i.e.,
base 10) number.
OnlinePaths
Number of online paths from within the displayed paths,
indicated by a decimal number. When the value of Paths
equals the value of OnlinePaths, then all the paths are online.
If the value of OnlinePaths is less than that of Paths, some
paths are offline. In this case, you should check the offline
paths and take appropriate action for any paths that have an
error status.
PathStatus
Status of the displayed paths. The displayed status indicates
the following:
•
Online: All paths are available.
•
Reduced: Some paths are not 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 all 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 all 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 error count reaches the
maximum value, it is reset, and the count is re-started 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 configuration is changed. When a new LU was
added and the host has not been restarted, AutoPATH_ID is
assigned to each path of the LU when you execute the cfgmgr
command.
PathName
#
1
-
The path name, which indicates a path. When you modify the
system configuration or replace a hardware item, you should
check the path names to identify the path that will be affected
by the change. Path name consists of the following four
elements, separated by periods:
•
HBA adapter number or adapter type (character string)
•
Bus number or adapter number (character string)
•
Target ID (hexadecimal number)
•
Host LU number (hexadecimal number)
