Dell EMC PowerFlex Rack Using PowerFlex Manager

Discover a resource

A resource must be discovered in PowerFlex Manager in order for PowerFlex Manager to manage it. A resource in PowerFlex Manager is categorized into one of the following groups: element manager, node, switch, VM manager, presentation server, or PowerFlex Gateway.

1. Access the Discovery Wizard by performing either of the following actions:
   • On the Getting Started page, click Discovery Resources.
   • On the menu bar, click Resources. On the Resources page, click Discover 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 a resource that you want to discover.
      • Element Manager, for example, CloudLink Center.
      • Node
      • Switch
      • VM Manager
      • Presentation Server
      • PowerFlex Gateway
   2. Enter the management IP address (or hostname) of the resources that you want to discover in the IP/Hostname Range field.

      To discover one or more nodes by IP address, select IP Address and provide a starting and ending IP address.

      To discover one or more nodes by hostname, select Hostname and identify the nodes to discover in one of the following ways:

      • Enter the fully qualified domain name (FQDN) with a domain suffix.
      • Enter the FQDN without a domain suffix.
      • Enter a hostname search string that includes one of the following variables:

        Variable	Description
        ${num}	Produces an automatically generated unique number.
        ${num_2d}	Produces an automatically generated unique number that has two digits.
        ${num_3d}	Produces an automatically generated unique number that has three digits.

        If you use a variable, you must provide a start number and end number for the hostname search.

   3. Select one of the following options from the Resource State list:

      Option	Description
      Managed	Select this option to monitor the firmware version compliance, upgrade firmware, and deploy services on the discovered resources. A managed state is the default option for the switch, vCenter, element manager, and PowerFlex Gateway resource types. Resource state must be set to Managed for PowerFlex Manager to send alerts to Secure Remote Services.
      Unmanaged	Select this option to monitor the health status of a device and the firmware version compliance only. The discovered resources are not available for a firmware upgrade or deploying services by PowerFlex Manager. This is the default option for the node resource type. If you did not upload a license in the Initial Setup wizard, PowerFlex Manager is configured for monitoring and alerting only. In this case, Unmanaged is the only option available.
      Reserved	Select this option to monitor firmware version compliance and upgrade firmware. The discovered resources are not available for deploying services by PowerFlex Manager.

   4. To discover resources into a selected node pool instead of the global pool (default), select an existing or create a node pool from the Discover into Node Pool list. To create a node pool, click the + sign to the right of the Discover into Node Pool box.
   5. Select an existing or create a credential from the Credentials list to discover resource types. To create a credential, click the + sign to the right of the Credentials box. PowerFlex Manager maps the credential type to the type of resource you are discovering. The credential types are as follows:
      • Element manager
      • Node
      • Switch
      • vCenter
      • Presentation Server
      • PowerFlex Gateway

      The default node credential type is Dell EMC PowerEdge iDRAC Default.

   6. If you want PowerFlex Manager to automatically reconfigure the iDRAC nodes it finds, select the Reconfgure discovered nodes with new management IP and credentials check box. This option is not selected by default, because it is faster to discover the nodes if you bypass the reconfiguration.
   7. To have PowerFlex Manager automatically configure iDRAC nodes to send alerts to PowerFlex Manager, select the Auto configure nodes to send alerts to PowerFlex Manager check box.
4. Click Next.

   You might have to wait while PowerFlex Manager locates and displays all the resources that are connected to the managed networks.

   To discover multiple resources with different IP address ranges, repeat step 2 and 3.

5. On the Discovered Resources page, select the resources from which you want to collect inventory data and click Finish.
   The discovered resources are listed on the Resources page.
