Looking back up at the article there are 4 supported IPMI interfaces: <ul> <li>open - Linux OpenIPMI interface</li> <li>imb - Intel IMB</li> <li>lan - IPMI v1.5 LAN interface</li> <li>lanplus - IPMI v2.0 RMCP+ LAN interface</li> </ul> Using one of the Dell 2850’s I have in my home lab that only supports IPMU v1.5 if I run the same command you did (<strong><em>with -I lanplus</em></strong>) I get the same results. <img src="http://cars.lostroncos.org/wp-content/uploads/2009/05/ipmi_lanplus_fail.png"/> However if I use the<strong> <em>‘lan’</em></strong> interface it works just fine. <img src="http://cars.lostroncos.org/wp-content/uploads/2009/05/ipmi_lan_work.png" alt=> Using the v1.5 lan interface and the <strong><em>delloem sysinfo</em></strong> command I can see that this server only supports IPMI v1.5. <img src="http://cars.lostroncos.org/wp-content/uploads/2009/05/ipmi_sysinfo.png"/> If I look at the RAC card on a newer 2950 I can see that it supports IPMI v2.0 <img src="http://cars.lostroncos.org/wp-content/uploads/2009/05/ipmi_rac_sysinfo.png"> If I run the same commands against the 2950 using ‘<strong><em>lanplus</em></strong>’ it works just fine. If you're sure that the server in question supports IPMI v2.0 a few other things to check: <ul> <li>Ensure that enable IPMI over lan or the equivalent is turned on. On the Dell 2950 this is a setting in the RAC config. </li> <li>Ensure that the user you're using is authorized or has privileges to connect via IPMI over Lan. (again on my 2950 it's a RAC setting)</li> <li>Check to make sure you haven't set the RMCP encryption to something by accident.</li> </ul> Hope this helps some... if not let me know... The first thing I’d ask based on the example you’ve shown me is whether or not you’re sure the server you’re trying to run this against supports IPMIv2. Looking back up at the article there are 4 supported IPMI interfaces:

  • open – Linux OpenIPMI interface
  • imb – Intel IMB
  • lan – IPMI v1.5 LAN interface
  • lanplus – IPMI v2.0 RMCP+ LAN interface

Using one of the Dell 2850’s I have in my home lab that only supports IPMU v1.5 if I run the same command you did (with -I lanplus) I get the same results.

However if I use the ‘lan’ interface it works just fine.

Using the v1.5 lan interface and the delloem sysinfo command I can see that this server only supports IPMI v1.5.

If I look at the RAC card on a newer 2950 I can see that it supports IPMI v2.0

If I run the same commands against the 2950 using ‘lanplus’ it works just fine. If you’re sure that the server in question supports IPMI v2.0 a few other things to check:

  • Ensure that enable IPMI over lan or the equivalent is turned on. On the Dell 2950 this is a setting in the RAC config.
  • Ensure that the user you’re using is authorized or has privileges to connect via IPMI over Lan. (again on my 2950 it’s a RAC setting)
  • Check to make sure you haven’t set the RMCP encryption to something by accident.

Hope this helps some… if not let me know…

Im trying to execute ipmi commands but getting some error

below mentioned is the command
ipmitool -I lanplus -H’host-name’ -U’user-name’ -P’password’ sensor

Error: Unable to establish IPMI v2 / RMCP+ session
Get Device ID command failed
Unable to open SDR for reading

can you provide more details on this , what all should we take in account when we going to execute ipmi commands
