The following shows examples of editing the /etc/lvm/lvm.conf file.
Figure 4-6 Example of Editing /etc/lvm/lvm.conf file
Comment out the existing filter and types lines, and add the shaded
lines in the figure.
Set 0 in md_component_detection.
Record the original md_component_detection value, because it is
necessary for removal or upgrade installation of HDLM.
28. Edit the /etc/fstab file.
Change the /boot mount point that you changed in step 5 from the SCSI
device to the HDLM device. Mark the existing SCSI device specification as
a comment by entering a hash mark (#) at the beginning of each line, and
then add the HDLM device specification as follows:
:
:
#/dev/sda1 /boot ext3 defaults 1 2
/dev/sddlmaa1 /boot ext3 defaults 1 2
:
:
This example assumes that IA32 uses GRUB as the boot loader. When you
use IPF that uses ELILO as the boot loader, the mount point is displayed
as /boot/efi instead of /boot in the line where /boot is coded, and the
file system type is displayed as vfat instead of ext3.
29. Specify the settings so that the HDLM device is not configured when the
host starts.
Change hdlm_dracut=n defined in the /etc/opt/DynamicLinkManager/
hdlm.conf file to hdlm_dracut=y.
30. Create an initial RAM disk image file for HDLM.
From the following, perform the procedure that corresponds to the host
OS.
