For example, add a method “fencemethod_ipmi” for both nodes:
CCS –h HA02.SH –addmethod fencemethid_ipmi HA01.SH
CCS –h HA02.SH –addmethod fencemethid_ipmi HA02.SH
5. Add a fence device for the fence method with the following command:
ccs -h host --addfencedev node1fence agent=fence_ipmilan
ipaddr=ipmi_ip login=ipmi_user passwd=ipmi_passwd auth=md5
action=off
For example, add the fence device node1fence and node2fence for node1 and
node2:
ccs –h HA02.SH --addfencedev node1fence agent=fence_ipmilan
ipaddr=192.168.144.21 login=admin passwd=password auth=md5
action=off
ccs –h HA02.SH --addfencedev node2fence agent=fence_ipmilan
ipaddr=192.168.144.32 login=admin passwd=password auth=md5
action=off
6. Add a fence instance for the fence method with the following command:
ccs -h host --addfenceinst fencedevicename node method
For example:
ccs -h HA02.SH --addfenceinst node1fence HA01.SH fencemethid_ipmi
ccs -h HA02.SH --addfenceinst node2fence HA02.SH fencemethid_ipmi
2.9.3 Create a Failover Domain
By default, all of the nodes can run any cluster service. A failover domain is a named subset of
cluster nodes that are eligible to run a cluster service in the event of a node failure. A failover
domain can have the following characteristics:
 Unrestricted – Allows you to specify that a subset of members is preferred, but that a
cluster service assigned to this domain can run on any available member.
 Restricted – Allows you to restrict the members that can run a particular cluster service.
If none of the members in a restricted failover domain are available, the cluster service
cannot be started (either manually or by the cluster software).
 Unordered – When a cluster service is assigned to an unordered failover domain, the
member on which the cluster service runs is chosen from the available failover domain
members with no priority ordering.
 Ordered – Allows you to specify a preference order among the members of a failover
domain. The member at the top of the list is the most preferred, followed by the second
member in the list, and so on.
