Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Enable storage data client authentication

Perform this procedure to enable storage data client authentication.

1. SSH into the primary MDM.
2. Type scli --login --username admin --management_system_ip <management_system_ip> to log in to the PowerFlex cluster using the provided credentials.
3. Type scli --set_sdc_authentication --enable to enable storage data client authentication feature.
4. Type scli --check_sdc_authentication_status to verify that the storage data client authentication and authorization is on, and that the storage data clients are connected with passwords.
   Sample output:

   [root@svm1 ~]# scli --check_sdc_authentication_status
   SDC authentication and authorization is enabled.
   Found 4 SDCs.
   The number of SDCs with generated password: 4
   The number of SDCs with updated password set: 4

5. If the number of storage data clients does not match or any storage data clients are disconnected, storage data clients, list any or all of the disconnected storage data clients and then disable the storage data client authentication by typing the following commands:

   scli --query_all_sdc | grep "State: Disconnected"

   scli --set_sdc_authentication --disable

6. Recheck the disconnected storage data clients to make sure that they have the proper configuration applied. If necessary, regenerate their shared password and reconfigure the storage data client. If you are unable to resolve the storage data client disconnection, leave the feature disabled and contact Dell Technologies support as needed.
