12. Restart the host.
Execute the following command to restart the host:
# shutdown -r now
A path will be established in the HDLM device and the HDLM manager will start.
13. If you have edited the
/etc/fstab
file as described in (1) Operations Required
for Devices to Be Managed by HDLM in 3.6.1 Preparations for a New
Installation of HDLM, add the line show below to change the setting from a SCSI
device specification to an HDLM device specification.
The Linux functionality that adds

HDLM. Do not use this functionality.
An example of how to edit the
/etc/fstab
file is shown in the following figure:
Add the shaded line shown in the above figure.
14. Specify the settings required for using LUKS.
Perform this step if your host OS uses LUKS. If HDLM manages a SCSI device
that has been configured to use LUKS, the LUKS settings must be migrated from
the SCSI device to an HDLM device.
For details on setting up LUKS, see 3.8 Settings for LUKS.
15. If md devices are used, execute the following command to activate them:
# mdadm -A -scan
mdadm: /dev/md0 has been started with 2 drives.
16. If md devices are used, execute the following command to make sure that they
have been activated.
In the following example, RAID1 (mirroring) is used:
# cat /proc/mdstat
