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.
-c
Specify this parameter to check the integrity of the storage-system-
migration definition file used when the -t parameter is specified. If the -c
parameter is specified, the utility reads the file, compares the existing
dlmfdrv.conf and the list of physical paths (storage system information)
in the destination system against the information that was read from the
file. The utility then outputs the comparison results to a file (/opt/
DynamicLinkManager/config/dlmfdrv.conf_check). The utility does not
create any configuration definition files.
-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.
Note
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.
-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
