Use the following dlmsetconf utility 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
The device mentioned in Devices Managed by HDLM on page 2-3 will be
set as an HDLM-managed device.
When the dlmsetconf utility is executed, the KAPL10242-I message will
be displayed prompting you to confirm the deletion of the logical device
files for the sd or ssd device.
If you respond by entering y, and then execute the dlmsetconf utility and
restart the node, with the reconfiguration option specified, the logical
device files of the sd or ssd device to be managed by HDLM will be
deleted. If the logical device files are already backed up, enter y and
execute the dlmsetconf utility. If the files are not backed up, respond by
entering n, and then cancel processing for the dlmsetconf utility. In this
case, back up the logical device files and execute the dlmsetconf utility,
by referring to step 4 in Performing Operations on Devices to Be Managed
by HDLM on page 3-45 of Preparations for a New Installation of HDLM on
page 3-45 .
When the dlmsetconf utility is executed and then the host is restarted
with the reconfiguration option specified, all sd or ssd devices connected
to the host will be set to be managed by HDLM.
Note
Restart the nodes simultaneously as shown in steps 12 and 13, after
the setup for LUs newly recognized on all nodes has completed.

.
If you are using VxVM, you need to disable, from VxVM, any devices
(such as sd or ssd devices) other than the HDLM devices corresponding to
the added LU.
Specify settings according to
Removing Devices from VxVM on a
Controller Basis on page 3-162 or Removing Devices From VxVM on a
Path Basis on page 3-166 of Removing Devices from VxVM on page
3-160 .

.
Stop all nodes in the cluster.
If the key is displayed in step 4, and nodes are running in non-cluster
mode in step 6, execute the following commands on all nodes:
# shutdown -g0 -y -i0
When running nodes in cluster mode, execute the following command on
any node:
# /usr/cluster/bin/scshutdown -g0 -y
