Newly discovered server is replacing previous server
Most of them are successfully "discovered" by our HP-SIM 5.2sp2. However, I have 5 servers for which the "discovery" process is having an issue:
- when discovering any first of the 5 servers, all is OK
- when discovering any of the 4 servers left, the first server is "replaced" by the newly discovered server.
- when discovering all of those 5 servers, only 1 entry is displayed in HPSIM device list with the servername = latest discovered server, but IP address = first discovered server
Looks like HPSIM "thinks" that all 5 servers are the same
Any hint how to solve this ?
thanks

Re: Newly discovered server is replacing previous server
Could you check if there is any DNS issues ?
Try to run the mxgethostname command on these nodes.

hope it helps

Re: Newly discovered server is replacing previous server
I have run the mxgethostname with the name of the 5 faulty servers, and returned names are all correct

Re: Newly discovered server is replacing previous server
Forward and reverse DNS ? HP SIM is quite touchy on the matter...

Re: Newly discovered server is replacing previous server
How were these servers deployed ? what OS are they running ?
Have you tried to delete those servers from HP SIM and readd them amnually one by one ?
Are they behind a firewall ?

Re: Newly discovered server is replacing previous server
What you are describing is totally correct on higher-end models of Proliant where you can install the "HP Insight Managements agents" (SNMP based).
However, in my case we are managing Proliant DL 180 models on which the "HP Insight Management agents" CANNOT be installed. We have to install the "HP Insight management WBEM provider" instead.
In that case, there is no hostGUID key in the registry. (HKLM\SOFTWARE\Compaq Insight Agent is non existing)
Is there another information in registry or files which is being used to identify uniquely the server?

Re: Newly discovered server is replacing previous server
on Proliant DL100 series, the GUID used to uniquely identify a server in HPSIM is provided by the UUID which is stored in the server NVRAM (or BIOS). Normally this UUID should be unique across all servers. However, we get some servers with a "non unique" UUID of the form "00112233445566778899aabbccddeeff"
As multiple servers were having the same UUID, HPSIM was seeing all those servers as a single server with mutiple IP addresses.
To solve that issue, you have to manually change the UUID on the affected servers. To change the UUID, you need to follow steps described at
