11 A cluster environment that shares resources has information that is
12 essential to correct operation which must be available to every node in
13 the cluster. This information may include: names of the nodes compos‐
14 ing the cluster, I/O fencing methods, and more. CCS is the system that
15 makes it possible for the nodes in a cluster to retrieve the informa‐
16 tion they need.

20 The following is a generic description of the steps one should take to
21 produce a working CCS environment.
22
23
24 Step 1
25 Choose a cluster name. It is important to determine a name for the
26 cluster before starting. The cluster name is what binds a machine to
27 specific resources that can only be shared by machines that are members
28 of the same cluster name.

31 Step 2
32 Create the directory /etc/cluster.
33
34
35 Step 3
36 Create the /etc/cluster/cluster.conf file, according to the clus‐
37 ter.conf(5) man page, on one node in your cluster.
38
39
40 Step 4
41 Start ccsd and test the cluster.conf file by using ccs_test. If you
42 haven't started a cluster manager yet, you should use the 'force'
43 option to ccs_test - see the ccs_test(8) man page for more info.
44
45 If a failure occurs while parsing the config file, ccs_test should
46 report "ccs_connect failed: No data available" and /var/log/messages
47 should report "Unable to parse /etc/cluster/cluster.conf".
