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 paths that will be affected by the change.
A 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)
• Host LU number (hexadecimal)
This path name is also the same as
PathName displayed by the dlnkmgr
command's
view operation. For details on the path name, see 6.7 view (Displays
Information).
DNum
A Dev number, which is equivalent to a logical volume number in AIX.
A Dev number beginning from
0 is assigned to the Dev in the LU.
In AIX, this value is fixed to
0 because one LU contains one Dev.
This is the same as the
DNum that is displayed by the dlnkmgr command's view
operation. For details on this operation, see 6.7 view (Displays Information).
HDevName
The name of the host device.
Hdisk name is displayed.
This is the same as the
HDevName that is displayed by the dlnkmgr command's
view operation. For details on this operation, see 6.7 view (Displays
Information).
