Edit the /etc/fstab file based on the checked results in steps 10 and 11
(this step is performed only when SCSI devices are output in step 10).
The following is an example of editing the /etc/fstab file, which was
edited in step 4:
(Before change)
:
#/dev/sddlmaa1 /boot ext3 defaults 1
2
LABEL=/boot /boot ext3 defaults 1 2
:
#/dev/sddlmaa3 swap swap defaults 0 0
LABEL=SWAP-sda3 swap swap defaults 0
0
:
(After change)
:
#/dev/sddlmaa1 /boot ext3 defaults 1
2
#LABEL=/boot /boot ext3 defaults 1 2
/dev/sddlmab1 /boot ext3 defaults 1 2
:
#/dev/sddlmaa3 swap swap defaults 0 0
#LABEL=SWAP-sda3 swap swap defaults
0 0
/dev/sddlmab3 swap swap defaults 0 0

Copy the lines in which devices are specified with UUID.
b
.
Comment out the copy-source lines by placing a hash mark (#) at the
beginning of each of the lines.
c
.
Change the devices described using UUID in the copied data to
descriptions using HDLM devices.

.
Restart the replication-destination host.
To apply the edited results obtained in step 12, restart the replication-
destination host by executing the following command:
# /sbin/shutdown -r now

.
Delete any unnecessary information regarding the HDLM devices that
were created on the replication-destination host.
Execute the HDLM configuration definition utility (dlmcfgmgr -u all -s)
to delete any unnecessary information about the HDLM devices.
An example of executing the command is as follows:
# dlmcfgmgr -u all -s
KAPL10340-E Several processes failed. See the /var/opt/
DynamicLinkManager/log/dlmcfgmgr1.log file. Check the message
output before this message.
The KAPL10340-E message is output. This does not affect HDLM
operation.

.
Execute the view operation of the HDLM command (dlnkmgr view -lu)
to verify that HDLM correctly recognizes the number of storage devices,
the number of LUs, and the number of paths.
An example of executing the command is as follows:
