Dell PowerFlex 4.5.x Administration Guide

Discover a PowerFlex system

Perform this task to discover a PowerFlex system.

1. Access the Discovery Wizard by performing either of the following actions:
   • On the Getting Started page, click Discover Resources.
   • On the menu bar, click Resources. On the Resources page, click Discover Resources on the All Resources tab.
2. On the Welcome page of the Discovery Wizard, read the instructions, and click Next.
3. On the Identify Resources page, click Add Resource Type, and perform the following steps:
   1. From the Resource Type list, select PowerFlex System.

      For a PowerFlex 4.x system, indicate whether the PowerFlex instance will be used for Production Storage or a Management Cluster.

   2. Enter the management IP addresses of the LIA nodes in the MDM Cluster IP Address field. You must provide the IP addresses for all the nodes in a comma-separated list. The list should include a minimum of three nodes and a maximum of five nodes.

      If you forget to add a node, the node will not be reachable after discovery. To fix this problem, you can rerun the discovery later to provide the missing node. You can enter just the one missing node, or all the nodes again. If you enter IP addresses for any nodes that were previously discovered, these nodes are ignored on the second run.

   3. For the System ID, specify the same System ID provided when you created the MDS cluster.
   4. Select an existing credential or create a new one from the Credentials list. The credential must be a PowerFlex Management System credential. Be sure to provide the LIA password that was used for the original setup. The LIA password is required for the mTLS configuration.
4. Click Next.
5. On the Summary page, click Finish.
   After you complete the discovery, you should see a PowerFlex System resource on the Resources page. The OS Hostname and Asset/Service tag are set to powerflex-mds. The discovery process also performs a bootstrap process that generates the required certificates and places them on the MDS nodes. Once you have completed the steps to discover a PowerFlex system, you must use the login certificate (not a username and password) to log in to the MDMs.
6. SSH to the two SVMs associated with the powerflex-mds system. Run scli --add_certificate --certificate_file /opt/emc/scaleio/mdm/cfg/mgmt_CA.pem.
