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

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)
For details about each element of the path name and its
representation in AIX, see
