SIM 5.3 only reports ip address in the system name column

[Raphaël Sougey]

Hi,

SIM 5.3 reports ip address in the most of system name column
The DNS configuration is fine on my NICs.

I launch many times the task/tool "Identify Systems" but I never have the system name updated by its real system name (instead of IP).
(The problem concerns Windows devices, or ESX servers...)

I don't know how I can force a refresh or debug this part ?

Thanks in advance for your help.

the DNS must be available in the network which can resolve the names for your discovered servers.

Hello,

Yes, this is the case but the "system name" value stay with the IP value.

Not sure the previous responder made this clear or not Raphaël, but the DNS records, both the forward (A) and reverse (PTR) records must exist and be correct for each system in order for SIM to correctly populate your system name and DNS entryies for each node. Make sure that the server you run SIM on can properly resolve the server names; nslookup is a good way to start.

options->security->system link configuration" select by full dns and discover/identify them again. done if system are really resolvable by ur dns.

i also have issues where SIM is not resolving Ip's to system name. I ahve followed the suggestions above but it doesnt seem to help. NSlookup on the SIM box resolves to a system name. Am running SIM 5.2

Any more suggestions?

thanks

Both forward and reverse lookups need to work correctly.
Use nslookup to resolve the IP Address to name and then again to resolve name back to IP Address.

it resolves via nslookup using ip address and the system name. But SIM still shows IP address in system name field. Is it a bug in SIM? does it need soem sort of patch applied?

Hi,

Yes exactly, I have the same problem.

Even so, you try and retry the "identify systems" function, the problem is the same.
(nslookup direct and reverse are OK)

Thanks for your help.

Once a system is discovered by its IP address fixing the DNS afterwards does not help. The only solution I know is deleting the system from the database, fixing the DNS, and doing a new discovery.

Look (or have your DNS admins look) at all the records for the zone your target system (the one you are adding, not SIM) and make sure you don't have duplicate records for the same IP address. The only time I've seen this is because there are multiple entries in DNS or because you don't wait long enough between your deletion and readdition of the server into SIM. If DNS is good, then delete the record in SIM and wait 15 minutes before you do a re-add. If you still have problems, try looking at your system and application (\logs\mx.log) to make sure you're not having some other failures occurring on the SIM server.
