HDLM information is missing in the /etc/init.d/boot.localfs file,
the /etc/init.d/boot.md file, or the /etc/init.d/lvm2 file.
Confirm that the HDLM information is missing by executing the
following commands:
# grep Required-Start /etc/init.d/boot.localfs
# grep Required-Start /etc/init.d/boot.md
# grep Required-Start /etc/init.d/boot.lvm
If the information in boot.hdlm is not output after command
execution, HDLM information is missing.

• HDLM and the Device-Mapper multipath function cannot be used
together.
You can check whether the Device-Mapper multipath function is enabled
by checking whether device-mapper-multipath is installed and
multipath devices are enabled.
Disable multipath devices if device-mapper-multipath is installed and if
multipath devices are enabled. For details on how to disable multipath
devices, see the device-mapper-multipath documentation. The
examples below show how to check whether device-mapper-multipath
is installed and whether multipath devices are enabled.
¢
If multipath devices are enabled:
# rpm -q device-mapper-multipath
device-mapper-multipath-0.4.9-46.el6.i686
#
# /sbin/multipath -l

If multipath devices are disabled:
If you execute the /sbin/multipath -l command, no information

Notes on Installing HDLM
• A license key is required to perform a new installation of HDLM.
To update the HDLM license, execute the dlnkmgr command's set -lic
operation. The expiration time of the license key is determined by the
type of license key specified in the license key file or entered by the user.
