System Name resolution

Leon_19 — Mon, 12 Jan 2004 21:13:56 GMT

I have recently installed SIM for testing and progressing well. However when the automatic discovery was performed SIM identified several devices, most devices did not gather a system name ie the ip adress appeared instead.

Initially I gathered that SIM was using DNS although when I checked for instance a HP switch which system name was not resolving it was entered within DNS. I have also added this in the host file.

How does SIM resolve the System Name on discovery ?

Can I manually change ?

Thanks

It uses DNS and I've found it is a bit fussier than CIM 7.

It seems to first resolve IP Address to Name but then also resolves the Name back to an IP Address.
So, you need and entry in both the Forward and Reverse Lookup tables.

I don't know that you can manually change it other than to override it with a Local Hosts File.

It may be worth spending the extra effort and getting DNS fully populated.

In our environement HPSIM resolves the name true DNS. Be sure that you have in your DNS also recursive DNS records that means that you should be able to resolve the name in a cmd box on the HPSIM like this

ping -a xxx.xxx.xxx.xxx (where xxx stand for the ipadress).

You should receive then the name from the system. But when there is no name returned you have no recursive DNS records in you DNS Server and have to create on.

Checked this while we had a wrong recursive DNS record with the wrong name and my system was then identified with the wrong server name.
