/dev/sddlmaa configured /dev/sda 0 0 0 0

KAPL10302-I /sbin/dlmcfgmgr completed normally.

The HDevName column indicates the HDLM device, and the Device column

indicates SCSI device.

Create an initial RAM disk image file for HDLM.
From the following, perform the procedure that corresponds to the host

OS.
For the initial RAM disk image file specified in the parameter, assign a

name that is different from all currently used names.

For Red Hat Enterprise Linux 6:

Change hdlm_dracut=n defined in the /etc/opt/
DynamicLinkManager/hdlm.conf file to hdlm_dracut=y.

Execute the dracut command.
The following shows an example of executing the command:

# /sbin/dracut /boot/initramfs-hdlm-2.6.32-71.el6.i686.img

`uname -r`

For OSs other than the above:
Execute the utility for supporting a boot disk (dlmmkinitrd).
For details on the dlmmkinitrd utility, see

Back up the /etc/fstab file.

Edit the /etc/fstab file.
Change the mount points for the following HDLM management-target

devices from the SCSI device to the HDLM device:

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

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

Comment out the existing SCSI device specification by placing a hash

mark (#) at the beginning of each line, and then add the HDLM device

specification as shown below, based on the correspondence between the

SCSI device and the HDLM device as checked in step 18.

#LABEL=/ / ext2 defaults 1 1

#/dev/sda2 / ext2 defaults 1 1

/dev/sddlmaa2 / ext2 defaults 1 1
