3. Creating an HDLM Environment
149
A path will be established in the HDLM device and the HDLM manager will start.
14. 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
LABEL=
to a SCSI device is not supported in
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.
15. 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.
16. Specify the settings required for using md devices.
If you want to use md devices, create them in a multi-path environment.
For details about the md device settings, see 3.9 Settings for md Devices.
17. Specify the settings required for using the volume management software.
If the logical volume created with the volume management software is already
being used, replace it with a logical volume whose physical volume is an HDLM
device.
For details on setting the volume management software, see 3.10 Settings for
LVM2.
18. Specify the settings required for using virtual environments.
When using Xen, set it up to use HDLM devices in domainU. When using KVM,
register HDLM devices into the hardware configuration file.
