3. Creating an HDLM Environment
173
1. Check the installation directory of the OS specified in the
LABEL
setting.
# cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
Confirm that LABEL indicates the root directory and the
/boot
directory.
2. Check the correspondence between the
LABEL
setting and the sd device.
# mount
/dev/sda2 on / type ext3 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/sda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
Confirm that the root directory is
/dev/sda2
, and the /
boot
directory is
/
dev/sda1
.
3. Using an editor such as vi, change the
LABEL
specification to an sd device
specification.
(before)
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
(after)
/dev/sda2 / ext3 defaults 1 1
/dev/sda1 /boot ext3 defaults 1 2
4. Install HDLM.
5. After configuring the HDLM device, execute the
dlmcfgmgr -o
command
to exclude the HDLM device that corresponds to the boot disk as a
management target.
„ If the SCSI device name has been changed by using the
udev
function, see
3.7.3 Settings for Using an HDLM Device as a Boot Disk and 3.7.4 Upgrade
Installation in an Environment Where an HDLM Device Is Used as a Boot Disk
and perform operations while reading the SCSI device names in those subsections
as the new SCSI device names (
udev
name) that were changed by using the
udev
function.
