Deploy Dell PowerFlex v3.6.x

Using SSH authentication on the PowerFlex Gateway

Create SSH keys for servers in a new or existing PowerFlex system.

1. Create the private and public key pair on the node where the PowerFlex Gateway is installed:
   1. In command line, run the command:

      cd ~/.ssh/

   2. Run the command:

      ssh-keygen -t rsa

      This command generates a private and public key. When performing this command, you can add a passphrase, or generate the key without a passphrase. Two SSH keys are produced: id_rsa and id_rsa.pub.
2. On one of the PowerFlex servers, run this command to store the public key in the authorized_keys file:

   cat ~/.ssh/id_rsa.pub | cat >> ~/.ssh/authorized_keys

3. Copy the .ssh directory to the rest of the PowerFlex servers.
4. Copy id_rsa.pub to the file system on the rest of the PowerFlex servers.
5. Use FOSGWTool in command line to upload the private key to thePowerFlex Gateway:

   FOSGWTool --update_ssh_key --ssh_key <PATH_TO_SSH_KEY_FILES> [--key_passphrase <KEY_PASSPHRASE>]

   The --key_passphrase is optional. Add this if you generated it when you created the key pair. During deployment, the gateway will use the private key for authentication.

6. Restart the PowerFlex Gateway service:
   • Windows: From the Windows Services window, restart the EMC ScaleIO Gateway.
   • Linux: Type the following command:

     service scaleio-gateway restart
