Discovery failed

Hello Prudhviraj,

I'm sorry to see OME is failing to connect the R730 on discovery.

I have a few things you can check. A few you have already done:

WSMAN uses Port 443, is it open?
Is the DRAC firmware up to date?
Ensure that the path between OMEnterprise and the target device is routable
Ensure that the device can ping the OMEnterprise appliance
Ensure that ping/ICMP isn't blocked (firewall) between OME and the target device
Confirm login credentials for iDRAC are correct
Log into the device that is failing to discover to verify the credentials used for the discovery are correct for that device
Try discovery using different account credentials
If password has special characters try an account that does not have special characters

Please let me know what you find.

Is there any progress on this post so We have this problem

Hi.

No, we didn't receive anything from the TO. So maybe you could let us know what steps have you already done?

Charles mentioned some steps in his post before - have you already done this?

Is it also an R730 that is affected?
How do other systems behave?

Let me know.

Hello, 

I am facing the same problem here, and I applied all the Charles steps successfully. 

please, what should be the next verification action here?

Hi we need to use below to troubleshoot.

I'm experiencing this as well [OME 3.5.0 (Build 60)] and for R#20 servers. After a mass password change, and successfully rediscovering the devices with the new credentials, most iDRAC 7 devices disconnected after a few days. I tried discovering a device using different credentials and the discovery task immediately failed.

The networking team says nothing is getting blocked. Where can I view more verbose and detailed logs?

Rgb_9,

To me it sounds like it could be a couple things. Would you do me a favor and confirm if the idracs are up to date, and have been restarted? The other thing is it sounds like there may be an issue with the network that the host OME system is on.  As far as logs you can enable Debug logs in the TUI and export them for additional information. 

Let me know what you see.

The iDRAC's are up and up-to-date. I reset a couple of them to test if that would fix it, and the symptoms were the same. The networking group assured me that nothing was getting dropped. I enabled Debug logs and restarted the OME services. How do I export them?

Update: I exported them from Monitor > Audit Logs > Export > Export Console Logs. Which logs do I view to see the discovery failures?

I'm looking in application.log but nothing is jumping out at me. These are the last lines after the IP.

I don't see stuff like ERROR or port numbers.

It should be found at application.log

After further investigation by the networking team, it was discovered that it was a recent change to a policy that caused the disconnections. After they added the application "dell-drac" to the policy, instead of just 443, I was able to rediscover the disconnected devices. It is odd that iDRAC 7 was affected and not iDRAC 6/8/9. It must behave a different way than the others.

Would you confirm if you reproduced the error after you enabled Debug? If not would you be able to and let us know what you see?

Thanks.

Hi Charles,

is ICMP required to be opened between OME and iDRAC? I'm trying to add/discover new R450 server on OME 3.9.0b55 and it fails with following message:

Network Address 172.29.200.15 is not reachable via ICMP PING.
Task Failed. Completed With Errors.

Hello Dariusz

Most of the time this is a network configuration issue. I have a couple other threads with similar issue you can review.

Also I'd recommend creating ga new discovery job, reference and video linked below:
