Server initiated discovery

Need clarification on the DNS entries needed to setup server initiated discovery. Not able to use the TUI method. Using Windows DNS. Thanks

Manually—Add the following three records to your DNS server on the network for which the interface is configured on the appliance. Ensure to replace all instances of domain or Subdomain.domain with the appropriate DNS domain and the system hostname.

  • _dcimprovsrv._tcp. domain 3600 PTR ptr.dcimprovsrv._tcp.domain
  • ptr.dcimprovsrv._tcp.domain 3600 TXT URI=/api/DiscoveryConfigService​/Actions/DiscoveryConfigService.​SignalNodePresence
  • ptr.dcimprovsrv._tcp.domain 3600 SRV 0 0 443 hostname.domain

We got it figured out. Have to add the DNS entries manually. Does not need to be enabled in the TUI if you setup DNS manually. Thanks all!

Hi, from an old post from the community:

"

If your nslookup is working and resolving the hostname to DNS name then OME should be showing the DNS name."

Yes nslookup works for resolving hostname and IP. What I am trying to setup is Server Initiated Discovery. I am not able to enable using the TUI of OME.

 

Discover servers automatically by using the server-initiated discovery feature

OpenManage Enterprise allows automatic discovery of servers that have iDRAC firmware version 4.00.00.00 or later. The appliance can be configured to allow these servers to automatically locate the console by querying the DNS and initiate their discovery .

Prerequisites
For a   server- initiated   discovery, the following prerequisites must be met:
  •  This feature is applicable only for servers with iDRAC firmware version 4.00.00.00 or later.
  • The servers must be on the same domain or subdomain as OpenManage Enterprise.
  • OpenManage Enterprise must be registered with the DNS to add the configuration information to the DNS by using TUI. It is preferred that the DNS allows automatic updates from OpenManage Enterprise.
  • Old records of the appliance console on the DNS, if any, should be cleaned up to avoid multiple announcements from the servers.
About this task

The following steps are followed for an automatic discovery of servers in OpenManage Enterprise :

Steps
  1. Add the configuration information of OpenManage Enterprise on the DNS using one of following methods:
    • TUI—By using the TUI interface, enable the Configure Server Initiated Discovery option. For more information, see Configure OpenManage Enterprise by using Text User Interface.
    • Manually—Add the following three records to your DNS server on the network for which the interface is configured on the appliance. Ensure to replace all instances of domain or Subdomain.domainwith the appropriate DNS domain and the system hostname.
      • _dcimprovsrv._tcp.domain 3600 PTR ptr.dcimprovsrv._tcp.domain
      • ptr.dcimprovsrv._tcp.domain 3600 TXT URI=/api/DiscoveryConfigService​/Actions/DiscoveryConfigService.​SignalNodePresence
      • ptr.dcimprovsrv._tcp.domain 3600 SRV 0 0 443 hostname.domain

Hi,

 

Are you not able to launch the TUI or do you get error from there?

Please share us screenshot that could help.
