Example 4
The

-u

parameter is specified:

Defines a non- HDLM-managed LU based on the contents of the definitions in

the HDLM driver unconfiguration definition file (

/opt/

DynamicLinkManager/config/dlmfdrv.unconf

):


# /opt/DynamicLinkManager/bin/dlmsetconf -u

Note

Execution of the

dlmsetconf

utility causes sd or ssd devices to be defined in

the HDLM driver configuration definition file (

/kernel/drv/dlmfdrv.conf

)

in units of LUs.

Executing the

dlmsetconf

utility outputs the KAPL10242-I message. Entering

y

in response to this message creates or updates the HDLM driver configuration

definition file (

/kernel/drv/dlmfdrv.conf

), the 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
