HP SIM 7.4 & ILO2 error

I'm fairly new to HP SIM and trying to add all our HP hardware into the SIM. Most of it works fine but I am having trouble adding two older serverens with a iLO2 controllers.

 

I have added the server credentials and according to the log SIM can log in just fine using SSH. However, when running the discovery process the following error is displayed:

********* Significant issues and overall target discovery/identification
          status:
Major:    The system cannot be identified properly for HP SIM to manage;
          unable to get one or more of the following: model, serial number or
          unique identifier (UUID). For management processors, verify the
          system is running the latest firmware. For Linux based operating
          systems, you must have dmidecode installed, enable the
          PermitRootLogin and PasswordAuthentication in sshd, and use root
          sign-in credential. For HP-UX, verify the sign-in credential. For
          Windows, check if WMIMapper is configured correctly on the CMS and
          verify the sign-in credential.
Critical: The system(s) can not be identified by WBEM, SNMP or SSH

 

I have tried manually setting the SSO trust using both cert and host name, adding the servername and cert to the iLO but with no luck.

I am sort of out of ideas so any help would be appreciated. For reference I have attached the full discovery log.

Thanks in advance.

Re: HP SIM 7.4 & ILO2 error

Hello,

 

did you add the Public SNMP community? Can you connect using HTTP and HTTPS?

Kind regards,

Re: HP SIM 7.4 & ILO2 error

Hi Andrew

Yes i added the public community, tried both with and without a capital P. I am able to connect just fine using HTTP and HTTPS and i have upgraded the firmware to the latest version using tge web interface.

Re: HP SIM 7.4 & ILO2 error

Did you install the latest hotfix of november? I've read a lot of people have problems with ILO2 but all looks fine here with the 7.4 version and the hotfix. Are the SIM server and ILOs separated by a firewall?
Kind regards,

Re: HP SIM 7.4 & ILO2 error

Yes I have installed the latest hotfix. After searching for a solution i read the same thing and I made sure the iLO firmware and SIM was the latest version.
One iLO is behind a firewall and a site-to-site VPN tunnel but all traffic is forwarded and we have no trouble with any other servers or services. The other is the same network as the SIM server so that one at least should have no problems.

Re: HP SIM 7.4 & ILO2 error

When i look at the log i see that SSH works, is the name/ip of a server? If so you try to discover the IP of the ILO instead. Can you confirm that you are discovering a server instead of an ILO?

Re: HP SIM 7.4 & ILO2 error

The server denies SSH logins but just to be sure I have double-checked and the IP is of the iLO and not the server.

Re: HP SIM 7.4 & ILO2 error

From your logfile :

 

Running SSH Protocol identification...

Normal: This system has SSH protocol support. * Running SSH Identification...

Normal: The system can be logged in using SSH protocol; has a valid SSH credential. 

 

So if you look at the object you discovered i bet you see credentials in the second tab.

the protocol that you see would be Ssh, nothing other because the credentials you have in SIM don't work.

Re: HP SIM 7.4 & ILO2 error

Im not sure I understand. The log states that SIM logs in using SSH just fine. The credentials used are the same as the HTTPS login which also works fine. Are there supposed to be any other credentials?

Re: HP SIM 7.4 & ILO2 error

When i discover an ILO all i need is snmp credentials and a https response. The credentials for snmp should be Public. Ssh is not required.

Re: HP SIM 7.4 & ILO2 error

You are correct that selecting the system, choosing the "Tools & Links" tab and then "System Credentials" i only have two; SSH and Sign-In and no SNMP credentials. However the SNMP credentials are configured in the discory rule with "Public" as the read community. Also, i dont seem to have SNMP credentials on any of the iLO3 servers either.

Re: HP SIM 7.4 & ILO2 error

That is strange indeed, do you have any ILO with SNMP working? If you look at the credentials you can edit these and add credentials. Please try to add Public at the SNMP, this will trigger a discovery job. Look at the log of this job to see if the SNMP works. Wich protocols do see when selecting tho ILO?

 

Believe me i know this can be frustating. .....

Re: HP SIM 7.4 & ILO2 error

I have checked the other ILOs and none of them have SNMP credentials enabled, even though the Public community string is entered in the discovery rule. I have checked and readded the Public community to both the system discovery and the global credentials and still it states that the system cant be identified.

I have attached the full discovery log for one ILO2.

The following lines however seem to indicate that SNMP is not enable on the ILO2.

        * Checking for SNMP protocol support on system...
Normal:   The system did not respond to SNMP. Verify security settings and
          community strings in Options->Security->Credentials->System
          Credentials
        * Checking for SNMPv3 protocol support on system...
Normal:   The system did not respond to SNMPv3. Verify security settings and
          v3 credentials in Options->Security->Credentials->System
          Credentials
        * Running HP ProLiant management agent identification...
Normal:   The system does not support SNMP.
        * Running SNMP base cluster identification using common cluster
          MIB...
Normal:   SNMP is not supported or globally disabled, skipping SNMP cluster
          identification.

Am i missing some configuration on the ILO? On the ILO3 servers only SNMPv3 fails.

I will run a identification of an ILO2 and paste the log tomorrow.

Re: HP SIM 7.4 & ILO2 error

Hello again,

 

I've attached the ILO2 log for one of my discovery of an ILO.

 

If you open the log you can see the following :

 

Normal:   The system responded to an SNMP request; it supports SNMP Protocol 
          and has a valid read community string.

 

And soon after that it logs the following :

 

Normal:   This system is a management processor; attempting to get associated 
          server information.

 

So the SNMP discovery told the SIM discovery that this is an ILO. I've disabled the SSH because i don't have SSH credentials. When i look at the recorded credentials i see Public from the Global source. When i look at the discovered Management Protocols i see HTTPS:1.0 and SNMP: 1.0.

 

The SIm version is 7.4 and the november fix is installed. You could try to increase the SNMP timeout just to be sure.

 

The ILO is of version 2.25, if you type https://ipadres/xmldata?item=All do you get the XML reply ?

 

Kind regards,

Re: HP SIM 7.4 & ILO2 error

I have checked again and run a new discovery with SNMP timeout increased to 30 seconds and it still fails.

Ive tried running an SNMP walk on the ILO but it doesnt respond.

Is it possible that the community isnt public? Or that i need to activate something on the ilo?

When i check https://ipadres/xmldata?item=All  i do get an XML reply.

For good measure in can confirm that the ILO version is also 2.25 and i am running SIM 7.4 with the November patch.

Re: HP SIM 7.4 & ILO2 error

I'm running out of options, is the firewall of the SIM  server active? If so try to disable it just to test that's not the problem. 

You could check if the traps directory under the SIM  installation has files in it, SIM uses this directory to buffer it's snmp traffic. This directorg thojld have files comming and going all the time. You could also set a Windows server to accept SNMP queries just to see if SNMP is eorking from scans of the SIM server. Just set if not already configered the SNMP  to Public and allow SNMP from the name or IP of your SIM server, set ghe datasource to SNMP and look if the System Management Homepage still shows system info.

 

This is all just for finding out what's wrong you can revert these setti gs when you find out the source of the problem.

 

Good luck.

Kind regards,

Re: HP SIM 7.4 & ILO2 error

I have already tried disabling the firewall on the SIM server. I didn't see much activity in the traps folder. I didnt have an HP server to test SNMP againt but i setup SNMP on a VMWare server and tried to descover it in SIM. The log states the following:

        * Checking for SNMP protocol support on system...
Normal:   The system responded to an SNMP request; it supports SNMP Protocol
          and has a valid read community string.

 

- so im assuming there are no general problems using SNMP.

 

I am considering factory resetting the iLO controllers on the two servers just to make sure nothing is configured incorrectly, even though I can't see what that would be.

Re: HP SIM 7.4 & ILO2 error

Indeed if this discovery worked SNMP seems just fine.

one thing you could try is load the MIB update. You are already running the last mibs but perhaps that there's a problem eith the existing MIBs.

 

Kind regards,

Andrew
