.
Execute the mount command to make sure that the HDLM device is
mounted.
The following shows an execution example for when GRUB is used as the
boot loader:
# mount
/dev/sddlmaa2 on / type ext2 (rw)
:
:
/dev/sddlmaa1 on /boot type ext2 (rw)
/dev/sddlmaa4 on /tmp type ext2 (rw)
/dev/sddlmaa5 on /var type ext2 (rw)
/dev/sddlmaa6 on /usr type ext2 (rw)
none on /dev/shm type tmpfs (rw)
Check the underlined section.

.
If Red Hat Enterprise Linux, or SUSE LINUX Enterprise Server is used,
make sure that the HDLM device is allocated to the swap partition.
Make sure that the HDLM device name is displayed in the Filename
column of the /proc/swaps file.
Settings for Using a Logical Volume (LVM2) on an HDLM Device as a
Boot Disk
This subsection describes how to migrate a single-path boot disk environment
that uses a logical volume (LVM2) on a SCSI device to a multi-path boot disk
environment that uses a logical volume on an HDLM device. Note that if the
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, or SUSE LINUX
Enterprise Server.
To migrate a single-path boot disk environment that uses a logical
volume (LVM2) on a SCSI device to a multi-path boot disk
environment that uses a logical volume on an HDLM device:
1
.
Log in to Linux as a user with root permissions.
2
.
If the OS is SUSE LINUX Enterprise Server 10 SP3 or later, specify
multipath=off in the boot loader configuration file.
Make sure that multipath=off has been set in the kernel line of the
boot loader configuration file. The following example shows how to specify
multipath=off:
¢
When ELILO is used as the boot loader:
:
:
image = vmlinuz-2.6.16.60-0.54.5-default
label = 51
append = "splash=silent multipath=off"
description = Linux
initrd = initrd-2.6.16.60-0.54.5-default
