Hello ac1750,

This is new release and it includes some new troubleshooting tools you can use.

Dell EMC OpenManage Enterprise 3.9 User's Guide :

https://dl.dell.com/content/manual56903993-dell-emc-openmanage-enterprise-3-9-user-s-guide.pdf?language=en-us&ps=true

Have you tried restart the appliance and check results?

Page 159: Troubleshooting tools. 

On the Monitor > Troubleshoot page.

Several troubleshooting capabilities are listed there as well as generating console logs.

Topics:

• Test protocol availability for any undiscovered device
• Test protocol availability for a discovered device
• Ping any device
• Test appliance connectivity
• Restart the appliance
• Test connection with network share
• Generate and download Console log archive
• (Field Service Debug is only used to internally debug issue within the OME appliance, and can only be enabled with assistance from a certified Dell support representative. It is recommended to call in and work with an engineer to use this option)

I saw one other case with the issue "is not reachable via ICMP PING" and they were able to check their firewall and resolve the issue.

Page 35-38: Supported protocols and ports on management stations , Supported protocols and ports on managed nodes

Check if required ports are open

did you update the iDRAC to 6.00.00.00 ?

If so, try to downgrade iDRAC to 5.xx.xx.xx
Looks like the latest OME + Services Plugin is not working with the latest iDRAC version.

The iDRAC IP is not set for the correct subnet, so fixing.

Hi @Dell -Charles R 

I am having the same issue reported above. Thanks for pointing to the troubleshooting page.

• I can communicate with the existing inventory
• I can not ping existing servers from the Monitor > Troubleshoot
• I can not discover newly added servers
• I can not ping newly added servers from the Monitor > Troubleshoot
• I can ping newly added servers from the OME hypervisor
• I can ping newly added servers from any other server on the network
• $ ping 10.19.45.104
  PING 10.19.45.104 (10.19.45.104) 56(84) bytes of data.
  64 bytes from 10.19.45.104: icmp_seq=1 ttl=58 time=0.730 ms

Hello Aniss L

Can you let us know what version OME you are on?

Does the new server ping the OME appliance ok?

Can you double check your network settings on the  like  ac1750 found incorrect subnet?

Other steps to try if you have not already:

*Reboot appliance

    *reboot the host (only if you can)

*Clear browser cache

*Try a different browser

Hello Aniss L,

Thank you for the reply.

What error does it give when you try to discover newly added servers?

Also list the steps you are taking to discover new servers.

Try discovering by OS. If Windows Server then discovery uses SSH on port 22

You may check this troubleshooting tutorial video. You may view the full video or  go to the 4:33 time mark

OpenManage Enterprise Discovery Troubleshooting.

Be sure to enable OpenSSH. 4:33 minute mark.

Can you update to OME 3.10?

You may need to contact Support directly for an engineer to do a remotes session with Debugging enabled to check the log.

>Can you let us know what version OME you are on?

Version 3.9.0 (Build 55)

Does the new server ping the OME appliance ok?

Yes it does from both the iDRAC racadm and  the host terminal

> Can you double check your network settings on the like  ac1750 found incorrect subnet?

all look good, as I said even the ones that I can manage I can not ping from the troubleshoot page. but I can verify ssh and ipmi from the same page
