Make sure that the logical device file of the sd or ssd device is backed up.
After you execute the

dlmsetconf

utility for creating the HDLM driver

configuration definition file in the next step(s) (either step 10, or steps 10 and 11)

and restart the host with the reconfiguration option specified, the logical device

files of the sd or ssd devices to be managed by HDLM will be erased. Before you

execute the

dlmsetconf

utility and restart the host, confirm that these files have

been backed up. For details on how to back up files, see (1) Performing

Operations on Devices to Be Managed by HDLM in 3.5.1 Preparations for a

New Installation of HDLM.

10. Execute the

dlmsetconf

utility as follows to create the HDLM driver

configuration definition file (

/kernel/drv/dlmfdrv.conf

) and the HDLM

driver unconfiguration definition file (

/opt/DynamicLinkManager/config/

dlmfdrv.unconf

).


# /opt/DynamicLinkManager/bin/dlmsetconf

in response to the KAPL10242-I message displayed when you execute the

dlmsetconf

utility.

Information pertaining to LUs to which the physical path accesses will be defined

in the HDLM driver configuration definition file (

/kernel/drv/

dlmfdrv.conf

). Do not edit this file.

11. Specify the devices that are to be excluded from management by HDLM, if there

are any.
This step is unnecessary if you want HDLM to manage all applicable devices.

Devices that cannot be managed by HDLM are automatically removed from the

HDLM driver configuration definition file. For details on devices that cannot be

managed by HDLM, see 2.1 Devices Managed by HDLM.
To remove devices from HDLM management, edit the HDLM driver

unconfiguration definition file (

/opt/DynamicLinkManager/config/

dlmfdrv.unconf

).
