Table 6-18 To display corresponding information about an HDLM device,
SCSI device, and LDEV
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
Logical Device Files for HDLM Devices on page 2-11 .
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.
