output to the event log. If this happens, refer to the KAPL05301-E

message to check the path information.

The message elements are explained below:

For details about the KAPL05301-E message, see When an LU or path is

automatically deleted due to all the paths being disconnected in

ErrorCode

The error number generated when Windows detects a path error.
When the Windows plug-and-play functionality deletes a SCSI device from

Windows, the path of the SCSI device changes to the offline status, and

the error number 0x00000000 is used. If this happens, by recovering the

path without using the automatic failback function, and letting Windows

recognize the SCSI device, the path will automatically change to the

online status.

PathID

The ID assigned to a path. This ID is called the AutoPATH_ID.

AutoPATH_IDs are re-assigned every time the host is restarted.
This path ID is the same as the path ID displayed in the Path List view in

the Path Management window.
The path ID is also the same as PathID displayed by the command's view

operation. For details on the view operation, see

PathName

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 PathName displayed by the command's
view operation. For details on the path name, see

DNum

A Dev number. A 0 is displayed for a Dev that takes up the entire LU.
This is the same as the DNum that is displayed by the view operation. For

details on the view operation, see

HDevName
