Item

Description

PathID

AutoPATH_ID indicated by a decimal number.
AutoPATH_ID is assigned when 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 HDLM-configuration definition utility
(

dlmcfgmgr

).

HDevName

Host device name.
The name of the logical device file (minus the partition number),

/dev/

sddlm

[aa-pap], for the HDLM device.

For details on logical device files for HDLM devices, see 2.6 Logical Device

Files for HDLM Devices.

Device

SCSI device associated with an HDLM device. If the SCSI device is not
connected when a host starts, or the assigned LU is released, this column

displays a hyphen (

-

).

This problem might also occur when the OS is SUSE LINUX Enterprise

Server 11 and one of the following problems occurs while the system is

running:

A path gets disconnected.
An LU is deleted.
A fiber cable connection is changed.
A Fibre Channel switch's zone setting is changed.

LDEV

The model ID, serial number, and iLU number for the storage system,
separated by periods. Information about LDEV can identify an actual device

that is managed by HDLM.
