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
