HDLM driver unconfiguration definition file (/opt/DynamicLinkManager/
config/dlmfdrv.unconf), and the HDLM nexus driver configuration
definition file (/kernel/drv/dlmndrv.conf). Entering n in response to
this message does not create or update those files.
• When the reconfiguration option is specified to restart the host after
executing the dlmsetconf utility, HDLM deletes the HDLM-managed
logical device files for sd or ssd devices.
• The HDLM driver configuration definition file (/kernel/drv/
dlmfdrv.conf) and HDLM nexus driver configuration definition file (/
kernel/drv/dlmndrv.conf) must not be edited. Editing these
configuration definition files might result in a failure to create the correct
logical device files for HDLM devices.
• If the dlmfdrv.conf and dlmndrv.conf files exist in either the /kernel/
drv directory or in a user-defined directory, the files are renamed
dlmfdrv.conf.bak and dlmndrv.conf.bak respectively, and saved as the
previous generation of the configuration definition files. If the
dlmfdrv.unconf file exists either in the /opt/DynamicLinkManager/
config directory or in a user-defined directory, the file is renamed
dlmfdrv.unconf.bak and saved as the previous generation of the
definition file.
• Even when the -d parameter is specified, existing definition information
is read from the /kernel/drv/dlmfdrv.conf and /kernel/drv/
dlmndrv.conf files, rather than from the dlmfdrv.conf and
dlmndrv.conf files in the specified directory.
• If the dlmsetconf utility finds an added path, in the HDLM driver
configuration definition file (/kernel/drv/dlmfdrv.conf) the utility adds
an entry (that is, a definition) to the definition of the LU for which the
path has been added. If any path has been deleted, the entry (definition)
is deleted from the definition of the affected LU. Whether a path is added
or deleted, existing instance numbers are inherited unless a new HDLM
driver configuration definition file (/kernel/drv/dlmfdrv.conf) file is
created.
• If the dlmsetconf utility finds any storage systems connected to a newly
added HBA, in the HDLM nexus driver configuration definition file (/
kernel/drv/dlmndrv.conf) the utility adds the entry (definition) for the
new HBA. Even when an HBA, to which one of the Hitachi storage
systems is connected, is deleted, the entry (definition) remains. Unless a
new HDLM nexus driver configuration definition file (/kernel/drv/
dlmndrv.conf) is created, the existing instance numbers are inherited,
and the entry is not deleted.
• If no configuration definition files (/kernel/drv/dlmfdrv.conf and /
kernel/drv/dlmndrv.conf) are found, the configuration definition files (/
kernel/drv/dlmfdrv.conf and /kernel/drv/dlmndrv.conf) are created
regardless of whether or not the -r parameter is specified.
• If an LU is deleted, you must delete the logical device files of the HDLM
devices corresponding to the deleted LU, which are stored in the /dev/
dsk or /dev/rdsk directory, before executing the dlmsetconf utility. If
