Use this procedure to manually prepare the CP server for use by the SFCFSHA cluster or clusters.

Table: Sample values in procedure displays the sample values used in this procedure.

Table: Sample values in procedure

CP server configuration component	Sample name
CP server	mycps1
Node #1 - SFCFSHA cluster	galaxy
Node #2 - SFCFSHA cluster	nebula
Cluster name	clus1
Cluster UUID	{f0735332-1dd1-11b2}

To manually configure CP servers for use by the SFCFSHA cluster

Determine the cluster name and uuid on the SFCFSHA cluster.
For example, issue the following commands on one of the SFCFSHA cluster nodes (galaxy):
```
# grep cluster /etc/VRTSvcs/conf/config/main.cf
```
```
cluster clus1
```
```
# cat /etc/vx/.uuids/clusuuid 
```
```
{f0735332-1dd1-11b2-bb31-00306eea460a}
```
Use the cpsadm command to check whether the SFCFSHA cluster and nodes are present in the CP server.
For example:
```
# cpsadm -s mycps1.symantecexample.com -a list_nodes
 
ClusName  UUID                                   Hostname(Node ID) Registered
clus1 	{f0735332-1dd1-11b2-bb31-00306eea460a} galaxy(0)         0
clus1 	{f0735332-1dd1-11b2-bb31-00306eea460a} nebula(1)         0
```
If the output does not show the cluster and nodes, then add them as described in the next step.

For detailed information about the cpsadm command, see the Veritas Storage Foundation Cluster File System High Availability Administrator's Guide.

Add the SFCFSHA cluster and nodes to each CP server.

For example, issue the following command on the CP server (mycps1.symantecexample.com) to add the cluster:

# cpsadm -s mycps1.symantecexample.com -a add_clus\
 -c clus1  -u {f0735332-1dd1-11b2}

Cluster clus1 added successfully

Issue the following command on the CP server (mycps1.symantecexample.com) to add the first node:

# cpsadm -s mycps1.symantecexample.com -a add_node\
 -c clus1 -u {f0735332-1dd1-11b2} -h galaxy -n0

Node 0 (galaxy) successfully added

Issue the following command on the CP server (mycps1.symantecexample.com) to add the second node:

# cpsadm -s mycps1.symantecexample.com -a add_node\
 -c clus1 -u {f0735332-1dd1-11b2} -h nebula -n1

Node 1 (nebula) successfully added

If security is to be enabled, check whether the CPSADM@VCS_SERVICES@cluster_uuid users are created in the CP server.
If the output below does not show the users, then add them as described in the next step.
```
# cpsadm -s mycps1.symantecexample.com -a list_users
```
```
Username/Domain Type  Cluster Name / UUID         Role

CPSADM@VCS_SERVICES@f0735332-1dd1-11b2/vx 
                     clus1/{f0735332-1dd1-11b2} Operator
```
If security is to be disabled, then add the user name "cpsclient@hostname" to the server instead of the CPSADM@VCS_SERVICES@cluster_uuid (for example, cpsclient@galaxy).

The CP server can only run in either secure mode or non-secure mode, both connections are not accepted at the same time.

Add the users to the CP server.

Issue the following commands on the CP server (mycps1.symantecexample.com):

# cpsadm -s mycps1.symantecexample.com -a add_user -e\
 CPSADM@VCS_SERVICES@cluster_uuid\
 -f cps_operator -g vx 

User CPSADM@VCS_SERVICES@cluster_uuid 
successfully added

Authorize the CP server user to administer the SFCFSHA cluster. You must perform this task for the CP server users corresponding to each node in the SFCFSHA cluster.
For example, issue the following command on the CP server (mycps1.symantecexample.com) for SFCFSHA cluster clus1 with two nodes galaxy and nebula:
```
# cpsadm -s mycps1.symantecexample.com -a\
add_clus_to_user -c clus1\
 -u {f0735332-1dd1-11b2}\
 -e CPSADM@VCS_SERVICES@cluster_uuid\ 
 -f cps_operator -g vx
```
```
Cluster successfully added to user
 CPSADM@VCS_SERVICES@cluster_uuid privileges.
