3. Creating an HDLM Environment

210

device. Note that if settings are incorrect, the OS might not start.
In this subsection, the procedure assumes that you are using

GRUB

or

ELILO

as the

default boot loader in Red Hat Enterprise Linux, SUSE LINUX Enterprise Server 10,

or SUSE LINUX Enterprise Server 11.
To perform an upgrade installation of HDLM in a multi-path boot disk environment

that uses a logical volume (LVM2) on an HDLM device:
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.


:
:
/dev/sddlmaa1 /boot ext3 defaults 1 2
:
:

This example assumes that IA32 uses

GRUB

as the boot loader. When you use IPF

that uses

ELILO

as the boot loader, the mount point is displayed as

/boot/efi

instead of

/boot

in the line where

/boot

is coded, and the file system type is

displayed as

vfat

instead of

ext3

.

3.

Execute the HDLM-configuration definition utility (

dlmcfgmgr)

with the

-v

parameter specified to check the correspondence between the HDLM device and

the SCSI device.


# dlmcfgmgr -v
HDevName Management Device Host Channel Target Lun
/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 the SCSI device.

4.

Edit the

/etc/fstab

file.

Change the

/boot

mount point that you checked in step 2 from the HDLM device

to the SCSI device. Comment out the existing HDLM device specification by

placing a hash mark (

#

) at the beginning of each line, and then add the SCSI

device specification as shown below, based on the correspondence between the

HDLM device and the SCSI device as checked in step 3.
