Deploying protocols on an existing cluster

Use this information to deploy protocols on an existing cluster by using the installation toolkit.

Designate the installer node by using the following command:
```
./spectrumscale setup -s Installer_Node_IP 
```
Designate protocol nodes in your environment to use for the deployment by using the following command:
```
./spectrumscale node add FQDN -p
```
Designate GUI nodes in your environment to use for the deployment by using the following command:
```
./spectrumscale node add FQDN -g
```
Configure protocols to point to a shared root file system by using the following command:
```
./spectrumscale config protocols -f FS_Name -m FS_Mountpoint
```
On the administrator node and all the protocol nodes, add a list of the pool of export IP addresses to the /etc/hosts file.
Example where the list of pool of export IP addresses is added to the hosts file
In this example, the Comma_Separated_List_of_Exportpool_IPs is 9.12.53.169,9.12.53.170,9.12.53.171,9.11.53.172.
```
/etc/hosts
9.12.53.169 ces1
9.12.53.170 ces2
9.12.53.171 ces3
9.11.53.172 ces
```

Configure the pool of export IP addresses by using the following command:

./spectrumscale config protocols -e Comma_Separated_List_of_Exportpool_IPs

Enable NFS on all protocol nodes by using the following command:
```
./spectrumscale enable nfs
```
Enable SMB on all protocol nodes by using the following command:
```
./spectrumscale enable smb
```
Review the configuration before deployment by using the following command:
```
./spectrumscale config protocols

./spectrumscale node list
```
Deploy protocols on your defined environment by using the following command:
```
./spectrumscale deploy --precheck
./spectrumscale deploy
```
