3.13 Settings for Heartbeat
This section describes the procedure that the user must perform when HDLM is
installed in an environment in which Heartbeat is used for SUSE LINUX Enterprise
Server.
To set up Heartbeat:
1.
Stop the Heartbeat service in the cluster.
If the Heartbeat service is running, stop it by executing the following command:
# etc/init.d/heartbeat stop
2. Migrate the SCSI devices used by Heartbeat to HDLM devices.
If a SCSI device that is subordinate to an HDLM device is being used as a file
system resource, edit the settings as shown in the following example:
# host1 172.26.4.321 Filesystem::/dev/sda::/mnt/point::ext3
host1 172.26.4.321 Filesystem::/dev/sddlmaa::/mnt/
point::ext3
In this example, the line that defines the SCSI device
/dev/sda
is commented
out, and the HDLM device
/dev/sddlmaa
is added.
3. Start the Heartbeat service in the cluster.
Execute the following command to start the Heartbeat service:
# /etc/init.d/heartbeat start
