Removing HDLM When an HDLM Device Is Used as a Boot Disk

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 3-258

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

.

Make sure that the HDLM device is defined in the /etc/fstab file.
Make sure that the mount points for the following HDLM management-

target devices are defined so that the HDLM device will be mounted:

¢

When ELILO is used as the boot loader:
Root directory (/), /boot/efi, /tmp, /usr, /var, swap

¢

When GRUB is used as the boot loader:
Root directory (/), /boot, /tmp, /usr, /var, swap
