A resource must be discovered in
PowerFlex Manager in order for
PowerFlex Manager to manage it.
Prerequisites
Before you start discovering a resource, complete the following:
Gather the IP addresses and credentials that are associated with the resources.
Ensure that both the resources and
PowerFlex Manager are connected to the network.
About this task
A resource in
PowerFlex Manager is categorized into one of the following groups: Element Manager, Node (Hardware/Software Management), Switch, VM manager,
PowerFlex gateway, Node (Software Management) or PowerFlex System.
Steps
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.
On the
Welcome page of the
Discovery Wizard, read the instructions, and click
Next.
On the
Identify Resources page, click
Add Resource Type, and perform the following steps:
From the
Resource Type list, select a resource that you want to discover.
Element Manager, for example, CloudLink Center.
Node (Hardware / Software Management)
Switch
VM Manager
PowerFlex Gateway
Node (Software Management)
PowerFlex System
If you want to discover a software-only node or management VM (MVM) node with a credential that uses SSH key pairs, you must add the public keys to the nodes manually before performing the discovery. If you do not add the public keys first, the discovery fails.
The
PowerFlex System resource type is used to discover an MDS gateway.
For a
PowerFlex 4.x system, indicate whether the
PowerFlex instance will be used for
Production Storage or a
Management Cluster.
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.
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 resource groups 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
SupportAssist.
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 resource groups by
PowerFlex Manager. This option is the default for the node resource type.
If you have yet not uploaded a license,
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 resource groups by
PowerFlex Manager.
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.
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 that you are discovering. The credential types are as follows:
Element Manager
Node (Hardware/Software Management)
Switch
VM Manager
PowerFlex Gateway
Node (Software Management)
PowerFlex System
The default node (Hardware/Software Management) credential type is
Dell PowerEdge iDRAC Default.
If you want
PowerFlex Manager to automatically reconfigure the iDRAC nodes it finds, select the
Reconfigure 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.
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.
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 steps 2 and 3.
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.
