HP Hitachi Dynamic Link Manager Software Licenses - Manual (Page 341)

The path name indicates a physical path. When you modify the system
configuration or replace a piece of hardware, you should check the path
names to identify the physical paths that will be affected by the change.
A path name consists of the following four elements, separated by
periods:
¢
Host port number (hexadecimal)
¢
Bus number (hexadecimal)
¢
Target ID (hexadecimal)
¢
Host LU number (hexadecimal)
The path name is also the same as the PathName displayed by the
dlnkmgr command's view operation. For details on the path name, see
view (Displays Information) on page 6-34 .
DNum
A Dev number.
A hyphen (-) is displayed.
This is the same as the DNum displayed by the view operation. For details
on the view operation, see view (Displays Information) on page 6-34 .
HDevName
The name of the host device.
The logical device file name of the HDLM device which the path accesses,
minus the slice number, is displayed in the format cUtXdY (for example,
c6t5d0).
This is the same as the HDevName displayed by the view operation. For
details on the view operation, see view (Displays Information) on page
6-34 .
What To Do for a Path Error
When a path error is detected, HDLM performs a failover on the path and
outputs the KAPL08022-E message. This message indicates that an error has
occurred in the components, shown in the following figure, that make up the
path.
