The HDevName
column indicates the HDLM device, and the Device column
indicates the SCSI device.
23. Edit the /etc/lvm/lvm.conf file so that the LVM2 recognizes the HDLM
device, not the SCSI device.
Figure 3-19 Example of Editing /etc/lvm/lvm.conf file on page 3-143
shows examples of editing the /etc/lvm/lvm.conf file.

Set 0 in md_component_detection.
Record the original md_component_detection value, because it is
necessary for uninstallation or upgrade installation of HDLM.
24. Create an initial RAM disk image file for HDLM.
From the following, perform the procedure that corresponds to the host
OS.
¢
For Red Hat Enterprise Linux 6:
a. Change hdlm_dracut=n defined in the /etc/opt/
DynamicLinkManager/hdlm.conf file to hdlm_dracut=y.
b. Execute the dracut command.
If the initial RAM disk image file to be created already exists,
specify the -f parameter to overwrite the file.
The following shows an example of executing the command:
# /sbin/dracut /boot/initramfs-hdlm-2.6.32-71.el6.i686.img
`uname -r`

For OSs other than the above:
Execute the utility for supporting a boot disk (dlmmkinitrd).
