Parameters

-d output-directory-name
Specifies the name of the directory to which the configuration definition
file created by the dlmsetconf utility is to be output. This directory must
be specified as an absolute path. You cannot specify multi-byte
characters. If output-directory-name is omitted, the configuration
definition file will be created in the /kernel/drv directory. Create the
output directory before you execute the utility.
-r
Specify this parameter to invalidate the definition of an existing
configuration definition file to create a new configuration definition file
and an HDLM driver unconfiguration definition file. When this parameter is
omitted, definition information from the existing configuration definition
file and HDLM driver unconfiguration definition file is inherited, the
information on the changed configuration is added to and/or deleted from
the definitions in the HDLM driver configuration definition file (/kernel/
drv/dlmfdrv.conf), and the information on the changed configuration is
added to the definitions in the HDLM nexus driver configuration definition
file (/kernel/drv/dlmndrv.conf).
Do not specify the -r parameter when SDS or SVM is used. A change in
instance numbers (that is, the minor numbers for HDLM devices) due to
HDLM device reconfiguration will make metadevices and volumes
unavailable. If the -r parameter is not used, the instance numbers
defined in the existing configuration definition files are retained, and the
metadevices and volumes continue to be available even though the
configuration of the storage system has been modified.
This parameter cannot be used together with the -u parameter.
Note
-u
Depending on the contents of the HDLM driver unconfiguration definition
file (/opt/DynamicLinkManager/config/dlmfdrv.unconf) that defines
the LU you want to remove from HDLM management, in the existing
entries of the HDLM driver configuration definition file (/kernel/drv/
dlmfdrv.conf), only the attribute value that specifies whether or not the
LU is managed by HDLM is updated, and applied in the system when the
reconfiguration option is specified to restart the host.
When the -u parameter is specified, the entry is not added or deleted
even though the system configuration is changed (such as by adding or
deleting LUs). If the attribute value that specifies whether or not the LU is
managed by HDLM is not changed when the dlmsetconf utility is
executed with the -u parameter specified, the HDLM driver configuration
definition file (/kernel/drv/dlmfdrv.conf) is not updated. If the HDLM
driver unconfiguration definition file (/opt/DynamicLinkManager/config/
When the reconfiguration option is specified to restart the host after
executing the dlmsetconf utility with the -r parameter specified, a
new logical device file might be created. If a new logical device file is
created, delete the old logical device file.
