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

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
dlmcfgmgr
utility for managing the
HDLM configuration.

of the following four elements, separated by periods:
• Host port number (hexadecimal number)
• Bus number (hexadecimal number)
