In this case, if a problem occurs, use the log displayed on the console to
analyze the problem.
The dlmcfgmgr log created at startup is output to /etc/opt/
DynamicLinkManager/hdlmboot.log.
Once you have built an environment for starting the OS from an HDLM
device, you cannot change the boot disk.
If you do not use the storage systems disk set for the boot disk, before
you install HDLM, edit the /etc/fstab file in the following manner to
disable the LABEL specification and enable the sd device specification.
a. 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.
b. 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.
c. 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
d. Install HDLM.
e. 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,
