.
Execute the HDLM-configuration definition utility (dlmcfgmgr -v) to check
if the device you want HDLM to manage is not being managed.
If the Management status of the relevant HDLM device is represented as
unconfigured in the execution result, the device is not being managed by
HDLM. Perform this operation if necessary. If it is not necessary to check
this, go to step 3.

.
Execute the dlmcfgmgr utility (dlmcfgmgr -i
logical_device_file_name_of_HDLM_device ) on the relevant device
you want to HDLM to manage.
The specified device is managed by HDLM.
The following is an example of executing the dlmcfgmgr utility:
# /sbin/dlmcfgmgr -i name-of-logical-device-file-for-HDLM-device

.
Refer to /var/opt/DynamicLinkManager/log/dlmcfgmgr1.log or
execute the dlmcfgmgr utility (dlmcfgmgr -v) or the view operation
(dlnkmgr view -path) of the HDLM command to make sure that the
relevant device is now managed by HDLM.
The following is an example of executing the dlmcfgmgr utility:
# /sbin/dlmcfgmgr -v
Restoring the Path of an HDLM Device Started in Disconnected Status (When a
Restart Is Required)
This subsection describes how to restore the path to an HDLM device that was
in disconnected status (the cable was pulled out or broken) when the host
first started. In this method, the host is restarted. Note that this operation is
applicable to an HDLM device managed by HDLM only. Also note that the
target path of restoration can be a single, multiple, or all paths to the
relevant HDLM device.
To restore the path of an HDLM device started in disconnected status
(this procedure restarts the host):

.
Execute the HDLM-configuration definition utility (dlmcfgmgr -v) or the
view operation (dlnkmgr view -drv) of the dlnkmgr command to check
if the host was started while the path to the relevant HDLM device was in
disconnected status.
The following are examples of executing the command or utility:
When executing the dlmcfgmgr utility with the -v option:
# /sbin/dlmcfgmgr -v
When executing the view operation with the -drv option:
# /opt/DynamicLinkManager/bin/dlnkmgr view -drv
