If you performed step 4, the host does not have to be restarted. Go to
step 6.

.
Execute the HDLM-configuration definition utility (dlmcfgmgr -v) or the
view operation of the dlnkmgr command (dlnkmgr view -drv)
(optional).
Check if the SCSI device name of the HDLM device whose path was
deleted in the above step 2 is represented with a hyphen (-).
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
Perform this operation if necessary. If it is not necessary to check this, go
to step 7.
If the SCSI device name is not represented with a hyphen (-), to change
the SCSI device name to a hyphen, wait until the path health checking
has been executed or execute the following dlnkmgr command with the
AutoPATH_ID of the HDLM device.
Example:
# /opt/DynamicLinkManager/bin/dlnkmgr online -pathid AutoPATH_ID

.
Execute the dlmcfgmgr utility (dlmcfgmgr -
ulogical_device_file_name_of_HDLM_device ) on the relevant HDLM
device whose path was deleted in the above step 2 to unregister the
HDLM device.
Path information on the relevant HDLM device is deleted.
The following is an example of executing the dlmcfgmgr utility:
# /sbin/dlmcfgmgr -u name-of-logical-device-file-for-HDLM-device
If you execute the dlmcfgmgr utility (dlmcfgmgr -u) when a path to the
HDLM device exists (for example, when you change a multi-path
configuration to a single-path configuration), the KAPL10340-E message
is output. In this case, take action according to this message and refer to
the /var/opt/DynamicLinkManager/log/dlmcfgmgrn.log file (where n is
1 or 2). If the KAPL10362-W message was output to the /var/opt/
DynamicLinkManager/log/dlmcfgmgrn.log file, HDLM operations are not
affected. Go to step 8.

.
Refer to the /var/opt/DynamicLinkManager/log/dlmcfgmgr1.log or
execute the dlmcfgmgr (dlmcfgmgr -v) to check if the path mapped with
the relevant HDLM device is deleted.
The following is an example of executing the dlmcfgmgr utility:
