In the next step, you will edit the /etc/fstab file so that a HDLM device
is mounted on each mount point. To do this, follow the procedure below
to check the HDLM device name that corresponds to each item.

.
Check the HDLM device name from the SCSI device name.
Execute the HDLM configuration definition utility (dlmcfgmgr) and
specify the -v parameter to check the HDLM devices that corresponds
to the SCSI devices.

The HDLM device name is displayed in the HDevName column and the
SCSI device name is displayed in the Device column.

.
From the LABEL specification, check the HDLM device name from
LABEL.
Execute the OS command findfs LABEL={LABEL-value}, and check
the device name that corresponds to LABEL. If a SCSI device name is
displayed, change it to the corresponding HDLM device name based
on the results of a..
# /sbin/findfs LABEL=/
/dev/sddlmaa2

Note
Depending on the environment you are using, you might not be
able to obtain information even if you specify the LABEL of a swap
in the findfs command. In such a case, execute /bin/cat /proc/
swaps and check which device is used by the swap. In addition, if
you know the LABEL of the swap, record it, because it is necessary
when uninstalling HDLM.

.
From the UUID specification, check the HDLM device name from
UUID.
Execute the OS command findfs UUID={UUID-value} to check the
device name that corresponds to UUID. If a SCSI device name is
displayed, change it to the corresponding HDLM device name based
on the result of a..
# /sbin/findfs UUID=b74637c2-59bb-4bca-94f0-94a96325b73f

.
From the specification of a device name (udev name) that starts
with /dev/disk, check the HDLM device name that corresponds to the
device name (udev name) that starts with the /dev/disk directory.
Execute the OS command readlink -f {udev-name} to check the
device name that corresponds to the udev name. If a SCSI device
