HP XP P9500 Storage - Manual (Page 440)

definition file (/kernel/drv/dlmfdrv.conf) is not updated. If the HDLM
driver unconfiguration definition file (/opt/DynamicLinkManager/config/
dlmfdrv.unconf) contains an invalid entry or does not exist, an error
occurs.
-t
Specify this parameter to inherit the device-name properties (logical
device names) in the existing dlmfdrv.conf as the device-name
properties (logical device names) of the logical units in the destination
storage system. This will retain the current HDLM logical device names
after migration.
If the -t parameter is specified when the storage-system-migration
definition file (/opt/DynamicLinkManager/config/dlmmiginfo.conf) has
not been used:
The logical device name for an LU is inherited only when the host LUN
in the existing dlmfdrv.conf and the host LUN of the destination
storage system are the same. Note, however, that the logical device
name inheritance system is not supported if the host LUNs of the
source or destination storage system are not unique.
If the -t parameter is specified when the storage-system-migration
definition file (/opt/DynamicLinkManager/config/dlmmiginfo.conf) has
been used:
The utility compares the storage system and LU information of the
source and destination storage systems in the storage-system-
migration definition file against the existing dlmfdrv.conf and
storage system information of the destination storage system. The
utility then inherits only the logical device names of the matched LUs.
Examples
Example 1
Parameters are omitted:
A configuration definition file is created in the /kernel/drv directory. If
the configuration definition file already exists, the existing definition
information is inherited, and the parts for the changed configuration are
added and/or deleted.
# /opt/DynamicLinkManager/bin/dlmsetconf
Example 2
The -d parameter is specified:
A configuration definition file is created in the /tmp directory:
# mkdir /tmp/dlmdir
# /opt/DynamicLinkManager/bin/dlmsetconf -d /tmp/dlmdir
