Hi, for AIX server discovery you need valid SSH credentials, please make sure they are added (and tested) to ServiceNow credential list.

Yes Appli
We have already created the AIX Credential entry in the credential list.Earlier the devices were getting discovered also.But now older Ips are also not getting discovered when we are running 'Quick Discovery' and also for new IP address it is giving error.

Hi, thank you. since it is not isolated to one host/ip, apparently issue is more generic.

Can you please check if these MID server properties are set to true?

Hi,

Did you test the credential and verify if the right MID server is tagged to it? It might be present in Affinity due to any credential match but it might not be working now or something must have changed and for that its better to check the 'Test' as from the discovery log its clearly stating its not able to find any credential.
