You can discover new resources or existing resources that are already configured within your environment. After discovery, you can deploy resource groups on these resources from a template. Only administrator-level users can discover resources.
By default, the operational state for all discovered nodes is
Unmanaged. If you want to perform firmware updates or deployments on a discovered node, select the node and change the operational state to
Managed.
If you have not yet uploaded a license,
PowerFlex Manager is configured for monitoring and alerting only. In this case, all the resources are restricted to the
Unmanaged resource state, and you cannot change the state to
Managed or
Reserved.
For some resources such as nodes, the default credentials are prepopulated in
PowerFlex Manager. If the credentials are changed from the defaults, add the credential to
PowerFlex Manager with the new login information.
Element Manager discovery
The IPI cabinet is discovered as an element manager. Once
PowerFlex Manager discovers the IPI cabinet, you can view cabinet details or you can open the IPI appliance management application to view more details.
The CloudLink Center is discovered as an element manager. If you create your own username in CloudLink Center, you need the SecAdmin access role and the local user type for the new user to complete discovery. The client user type does not work for discovery in
PowerFlex Manager. If one member of a cluster of CloudLink Center is shut down, the inventory still succeeds because
PowerFlex Manager falls back to inventorying the other CloudLink Center members if the first one is down.
Node discovery
PowerFlex Manager supports
PowerFlex node discovery and allows you to onboard nodes by configuring the initial management IP address and iDRAC credentials. To perform initial discovery and configuration, verify that the management IP address is set on the node and that
PowerFlex Manager can access the IP address through the network. While configuring IP addresses on the node, verify that
PowerFlex Manager can access any final IP address in a range used for hardware management, to complete discovery of these nodes.
PowerFlex Manager also allows you to use name-based searches to discover a range of nodes that were assigned IP addresses by DHCP to iDRAC. You can search for a range of DNS hostnames or a single hostname within the
Discovery Wizard. After you perform a name-based discovery,
PowerFlex Manager operations to the IDRAC continue to use name-based IP resolution, since DHCP may assign alternate addresses.
Switch discovery
If you attempt to discover a Cisco switch with terminal color configured, the discovery fails. To discover the switch successfully, disable the terminal color option by running
configure no terminal color persist.
VM manager discovery
A VMware vCenter is discovered as a VM manager.
PowerFlex Manager users with the administrator role can discover a vCenter in
PowerFlex Manager. A vCenter read-only user can discover a vCenter in
PowerFlex Manager only after the following requirements are met:
The vCenter user who is specified in the vCenter credential is granted the
VirtualMachine.Provisioning.ReadCustSpecs and
StorageProfie.View privileges.
The permission containing these privileges is granted to that user on the root vCenter object and the
Propogate to children property is set to
True.
PowerFlex Manager allows you to deploy new hyperconverged and compute-only resource groups and add existing resource groups to a vCenter that has an Enhanced Linked Mode (ELM) configuration. ELM connects multiple vCenter servers, allowing you to search across servers and perform other vCenter management functions. ELM does not provide clustering or redundancy.
If you are working with a vCenter that has an enhanced linked mode configuration, you must discover only the vCenter to which you want to deploy or add an existing resource group. You do not need to discover the other vCenters that are connected through the enhanced linked mode configuration.
