3.8 Settings for LUKS
This section explains the procedures that the user must perform when using LUKS.
3.8.1 Notes on Using LUKS
The followings are notes on using LUKS:
• HDLM supports LUKS on the following OSs:
• Red Hat Enterprise Linux 5.3
• Red Hat Enterprise Linux 5.3 Advanced Platform.
• Red Hat Enterprise Linux 5.4
• Red Hat Enterprise Linux 5.4 Advanced Platform.
• Red Hat Enterprise Linux 5.5
• Red Hat Enterprise Linux 5.5 Advanced Platform.
• Red Hat Enterprise Linux 5.6
• Red Hat Enterprise Linux 5.6 Advanced Platform.
• Red Hat Enterprise Linux 6
• LUKS is not available in an environment where an HDLM device is used as a boot
disk.
• To set up LUKS on an HDLM device, execute the
/sbin/cryptsetup
command, which is the same way as setting up LUKS on SCSI devices.
• When using LUKS on an HDLM device, enter the HDLM device's device file
name in the
/etc/crypttab
file's second field.
3.8.2 Using HDLM in an LUKS Environment
This subsection describes how to migrate LUKS from a SCSI device environment
using LUKS to HDLM devices.
To migrate from
/dev/sdh
to
/dev/sddlmaa
:
1. Check the HDLM device to be migrated from the SCSI device.
Execute the HDLM-configuration definition utility (
dlmcfgmgr)
with the
-v
parameter specified to check the correspondence between the SCSI device and the
HDLM device.
The following shows an example of executing the
dlmcfgmgr
utility with the
specified
-v
parameter:
