Upgrade Dell PowerFlex to v3.6.x

Physical Linux servers

This topic describes how to change the authentication mode from non-secure to secure on physical Linux servers.

Before beginning, verify the version of the OpenSSL on the server, by running this command:

rpm -qa | grep -i openssl

If the version is 1.1 or later, you can continue. If it is not, secure authentication cannot be enabled.

Log in to the SCLI, in a non-secure fashion:
scli --login --username <USER> --password <PASSWORD> --use_nonsecure_communication
Change to internal secure mode, by running the following command:
scli --set_component_authentication_properties --use_authentication --use_nonsecure_communication
Change to external secure mode, by running the following command:
scli --set_management_client_communication --enable_client_secure_communication --use_nonsecure_communication
Enable secure LIA authentication, by performing the following:

NOTE: This procedure can take quite some time, and there is no roll-back.
1. Log in to the PowerFlex Installer (https://<GW_Server_IP>)
  where <GW_Server_IP> is the IP address of the server where you installed the PowerFlex Gateway package.
2. Click the Maintain tab.
3. From the Maintenance operation screen, perform the following:
  1. Type the primary MDM credentials.
  2. Type the LIA password.
  3. In Advanced Options, select Allow non-secure communication with LIAs.
  4. Click Retrieve system topology.
  5. If a certificate approval is required, approve it.
  6. Type the authentication credentials again.
  7. Click Retrieve system topology.
  8. Click Security settings and select Enable LIAs security.
  9. Type the authentication credentials again.
  10. Confirm the request, and click Enable LIAs security.
  11. If a certificate approval is required, approve it.
  12. When complete, click Mark operation completed.
