Discovery changing CI name everytime

[bgworld]

Hi All,

I am facing strange issue with discovery. A linux server with 3 dns names. Every time disovery runs it sets different CI name based on whatever dns name it finds first.

Interestingly, host name is not changing and coming as correctly.

For Ex.

Linux Server: myserver_truename@mycompany.com

Other DNS names: myserver_A@mycompany.com, myserver_B@mycompany.com, myserver_C@mycompany.com

Hostname: myserver_true@mycompany.com

Discovery on day 1 sets the CI name as myserver_A@mycompany.com

Discovery on day 2 sets the CI name as myserver_B@mycompany.com

Discovery on day 3 sets the CI name as myserver_C@mycompany.com

Hi,

Take a look at properties with "trusted host" on the doc site below.

Brajendra,

Go to Discovery Definition --> Properties and make your setting like below.

After that, your hostnames won't get updated by DNS.

Based on the impact please mark helpful or correct

Getting an issue In Discovery Need your help :

Ex.

Once discovery runs it updates (Name has changed from V62014PD@USMANSMDBPW08 to v62014pd@USMANSMDBPW08)

Next time discovery runs & updates (Name has changed from v62014pd@USMANSMDBPW08 to V62014PD@USMANSMDBPW08)

(from capital to small letter and next time  small Letter to capital letter of the CI name updates and no other attributes getting update)
