Summary
displayed
Paths Total number of displayed paths, indicated by a decimal
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, all 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 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 will re-start 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
32 - 1 (4294967295). If the total I/O error count
reaches the maximum value, it will re-start from 0..
PathID The AutoPATH_ID indicated by a decimal number.
The AutoPATH_ID is assigned every time the host is
restarted. When a new LU was added and the host has not
been restarted, AutoPATH_ID is re-assigned to each path of
the LU when you execute the HDLM-configuration definition
utility (dlmcfgmgr).
PathName
# - 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 physical path
that will be affected by the change. Path name consists of
the following four elements, separated by periods:
•
Host port number (hexadecimal number)
• Bus number (hexadecimal number)
• Target ID (hexadecimal number)
• Host LU number (hexadecimal number)
For details about each element of the path name and its
representation in Linux, see Table 6-13 Elements of a path
name on page 6-45 .
