Hitachi Dynamic Link Manager Software Users Guide for Linux

If a value other than 0 is displayed for Used, perform the operation
described in Operations on HDLM-Managed Devices on page 3-205, and
then perform steps 2 and 3 in
Removing HDLM on page 3-224 so that the
HDLM devices can no longer be used.
6. Execute the remove command.
Execute the following command to remove HDLM:
# rpm -e HDLM
7. Make sure that the remove processing has finished.
Execute the following command to make sure that the remove processing
has finished. The following shows the information that is output.
# rpm -qi HDLM
package HDLM is not installed
8. Start the processes and services stopped in step 2.
The cluster software and volume management software will start up after
the host starts.
If you have temporarily changed the settings so that domainU will not
automatically start in step 2, restore the previous settings.
Migration to a Single-path Boot Disk Environment
This subsection explains how to remove HDLM from a multi-path boot disk
environment that uses an HDLM device, and to change the environment to a
boot disk environment that uses a SCSI device. (Note that if settings are
incorrect, the OS might not start.)
When you remove HDLM, if the KAPL09019-E or KAPL09020-E message is
output, follow the directions in
Removing Hitachi Network Objectplaza Trace
Library (HNTRLib2) on page 3-231 to remove HNTRLib2. However, if the
KAPL09026-I message is output, since a program other than HDLM is using
Hitachi Network Objectplaza Trace Library (HNTRLib2), only HDLM will be
removed.
The following procedure describes how to set up a boot disk environment that
uses LVM2. This procedure assumes that grub is used as the boot loader.
To remove HDLM in such a configuration:
1. Log in to Linux as a user with root permissions.
2. Check whether LVM is used in the boot disk environment.
Execute the mount command to check the name of the devices mounted
on the root partition (/). If LVM is used, device names that contain the
VG name and LV name appear. The following shows an example of
executing the command.

If LVM is used:
# mount
/dev/mapper/vg00-lv00 on / type ext3 (rw)
