9. 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
Type
y
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
).
