In the subsequent explanations, the configuration definition file is indicated as the
HDLM driver configuration definition file (
/kernel/drv/dlmfdrv.conf
) and the
HDLM nexus driver configuration definition file (
/kernel/drv/dlmndrv.conf
).
7.6.1 Format
/opt/DynamicLinkManager/bin/dlmsetconf [-d
output-directory-name
]
[-r | -u]
7.6.2 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
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.
