Cluster Server 7.3.1 Configuration and Upgrade Guide - Solaris

Last Published: 2019-04-17

Product(s): InfoScale & Storage Foundation (7.3.1)

Platform: Solaris

Configuring the CP server using the installer program

Use the configcps option available in the installer program to configure the CP server.

Perform one of the following procedures:

For CP servers on single-node VCS cluster:	See “To configure the CP server on a single-node VCS cluster”.
For CP servers on an SFHA cluster:	See “To configure the CP server on an SFHA cluster”.

To configure the CP server on a single-node VCS cluster

Verify that the VRTScps package is installed on the node.
Run the installer program with the configcps option.
```
# /opt/VRTS/install/installer  -configcps
```
Installer checks the cluster information and prompts if you want to configure CP Server on the cluster.
Enter y to confirm.

Select an option based on how you want to configure Coordination Point server.

1) Configure Coordination Point Server on single node VCS system
2) Configure Coordination Point Server on SFHA cluster
3) Unconfigure Coordination Point Server

Enter the option: [1-3,q] 1.
The installer then runs the following preconfiguration checks:
- Checks to see if a single-node VCS cluster is running with the supported platform.
  The CP server requires VCS to be installed and configured before its configuration.
The installer automatically installs a license that is identified as a CP server-specific license. It is installed even if a VCS license exists on the node. CP server-specific key ensures that you do not need to use a VCS license on the single-node. It also ensures that Veritas Operations Manager (VOM) identifies the license on a single-node coordination point server as a CP server-specific license and not as a VCS license.

Restart the VCS engine if the single-node only has a CP server-specific license.

A single node coordination point server will be configured and 
VCS will be started in one node mode, do you want to 
continue?  [y,n,q]  (y)

Communication between the CP server and application clusters is secured by using the HTTPS protocol from release 6.1.0 onwards.
Enter the name of the CP Server.
```
Enter the name of the CP Server: [b]   cps1
```
Enter valid virtual IP addresses for the CP Server with HTTPS-based secure communication. A CP Server can be configured with more than one virtual IP address. For HTTPS-based communication, only IPv4 addresses are supported.
```
Enter Virtual IP(s) for the CP server for HTTPS, 
separated by a space:  [b]  10.200.58.231 10.200.58.232 
10.200.58.233
```
Note:
Ensure that the virtual IP address of the CP server and the IP address of the NIC interface on the CP server belongs to the same subnet of the IP network. This is required for communication to happen between client nodes and CP server.

Enter the corresponding CP server port number for each virtual IP address or press Enter to accept the default value (443).

Enter the default port '443' to be used for all the 
virtual IP addresses for HTTPS communication or assign the 
corresponding port number in the range [49152, 65535] for 
each virtual IP address. Ensure that each port number is 
separated by a single 
space: [b]  (443) 54442 54443 54447

Enter the absolute path of the CP server database or press Enter to accept the default value (/etc/VRTScps/db).
```
Enter absolute path of the database: [b] (/etc/VRTScps/db)
```

Verify and confirm the CP server configuration information.

CP Server configuration verification:

on system sys1? [y,n,q] y
Enter a valid IP address to configure NetworkHosts for NIC e1000g0
on system sys1: 10.200.56.22

Do you want to add another Network Host? [y,n,q] n

Enter the netmask for virtual IP addresses. If you entered an IPv6 address, enter the prefix details at the prompt.

```
Enter the netmask for virtual IP for 
HTTPS 192.169.0.220: (255.255.252.0)
```

Installer displays the status of the Coordination Point Server configuration. After the configuration process has completed, a success message appears.

For example:
Updating main.cf with CPSSG service group.. Done
Successfully added the CPSSG service group to VCS configuration.
Trying to bring CPSSG service group
ONLINE and will wait for upto 120 seconds

The Veritas coordination point server is ONLINE

The Veritas coordination point server has 
been configured on your system.

Run the hagrp -state command to ensure that the CPSSG service group has been added.
```
For example:
# hagrp -state CPSSG
#Group Attribute System Value
CPSSG State.... |ONLINE|
```
It also generates the configuration file for CP server (/etc/vxcps.conf). The vxcpserv process and other resources are added to the VCS configuration in the CP server service group (CPSSG).

For information about the CPSSG, refer to the Cluster Server Administrator's Guide.

To configure the CP server on an SFHA cluster

Verify that the VRTScps package is installed on each node.
Ensure that you have configured passwordless ssh or rsh on the CP server cluster nodes.
Run the installer program with the configcps option.
```
# ./installer -configcps
```
Specify the systems on which you need to configure the CP server.
Installer checks the cluster information and prompts if you want to configure CP Server on the cluster.
Enter y to confirm.

Successfully added the CPSSG service group to VCS configuration.

If the cluster is secure, installer creates the softlink /var/VRTSvcs/vcsauth/data/CPSERVER to /cpsdb/CPSERVER and check if credentials are already present at /cpsdb/CPSERVER. If not, installer creates credentials in the directory, otherwise, installer asks if you want to reuse exsting credentials.
```

```
For example:
# hagrp -state CPSSG
#Group Attribute System Value
CPSSG State cps1 |ONLINE|
CPSSG State cps2 |OFFLINE|
```
It also generates the configuration file for CP server (/etc/vxcps.conf). The vxcpserv process and other resources are added to the VCS configuration in the CP server service group (CPSSG).

For information about the CPSSG, refer to the Cluster Server Administrator's Guide.
