IPMI Troubleshooting

Issue: IPMI is not reachable

If Tenantos can't establish a connection to IPMI, the power status is unavailable and an "error" label is added to the IPMI device assignment.

Move the mouse to the error label to receive the exact error message:

To solve the issue, please:

• Ensure that the correct remote agent is selected.
• Ensure that the IPMI connection details are correct.
• Ensure that the remote agent can establish a connection to IPMI.

Ensure that the remote agent can establish a connection to IPMI

Connect via SSH to your remote agent and execute following command:

ipmitool -I lanplus -H IPMI_IP -U ADMIN -P YOUR_PASSWORD chassis power status

If you see the same error message as in Tenantos, ensure via ping that you can reach the IPMI device:

ping IPMI_IP

If ping is not possible

If ping is not possible, it's likely a connectivity issue. Please ensure that your agent has access into your IPMI network. If IPMI is located within a private network, please read this page to find out how to include the agent into your private network.

If ping is possible

• Ensure that IPMI over LAN is enabled at the IPMI settings, like on this screenshot.
• Some IPMI versions do not accept connections via RMCP if the default password has not been changed. If you are forced to change the password after logging in into the IPMI web interface, please do so.

Issue: KVM console does not work / Error: "KVM type not supported"

Tenantos natively supports a variety of different IPMI models, but unfortunately, IPMI web interfaces and consoles are not standardized and each vendor does its own implementation. Often IPMI even differs from model to model.

If you have servers that are not supported and you would like to see them integrated, please either provide access to them (e.g. via public IP or OpenVPN) or provide access to your Tenantos installation.

• If you provide access to your installation, please include in your request the link to the server and whether it is currently in use.
• If you provide direct access to the IPMI device or a tunnel, please whitelist the IPs mentioned on the following page.

After you have prepared everything, please send us the data via support ticket.

Issue: IPMI status "Error in open session response message : insufficient resources for session"

If you encounter this issue on iDRACs, the issue can be solved by following these steps:

Menu Overview -> IDRAC SETTINGS -> User Authentication
-> Click on the user ID of your admin account -> Next
-> Check "change your password" checkbox and enter the same (or new) password
-> Click "Apply"

Issue: HP iLO console not working due to "com.hp.ilo2.intgapp.intgapp"

If an outdated version of iLO is installed, an error message may appear when attempting to open the console, such as:

General Exception
Name: com.hp.ilo2.intgapp.intgapp
ExitException: ExitException[ 3]java.lang.StackoverflowError

To solve the issue, please update the iLO firmware. Once the firmware has been updated, the error message should no longer appear, and the console should function as expected.
