How to Reset iLO 2 (Not server reset )

Integrated Lights-Out 2, or iLO2 is an embedded server management technology exclusive to Hewlett-Packard but similar in functionality to the Lights out management (LOM) technology of other vendors. iLO 2  can remotely perform most functions that otherwise require a visit to servers at thedata center, computer room or remote location.

HP Integrated Lights-Out 2 (iLO) is a hardware component on the HP server. This is a card/chip  which is usually integrated to the system board. You do not need an Operating System for iLO2 to work. It is on Hardware level. iLO2 has it’s own network connection and IP, and through it you can take remote of the server and use it.

How to Reset iLO 2:

Have you ever wondered how to reset iLO2 if it gets slow or stuck? You may reset iLO2 if it gets stuck OR if you receive messages like “there is a session already in progress” etc, below provided are the different methods of resetting iLO2. Note that resetting iLO2 will not affect the functionality of server. You can reset iLO2 while the server is in production. Here in this post, I am sharing how you can reset iLO2.

Method 1:

You may reset iLO from iLO web browser itself, this is the easiest method.

1. Open the iLO web interface. (Enter iLO ip address in web browser for the log-in screen to appear)

5. Click OK button in response to “Are you sure you want to reset iLO 2”message.
6. It may take 30-60 seconds for the iLO to reboot. Be patient

For some users, clicking Apply button in Network settings of iLO 2 worked. This is happens because when we change any Network settings of iLO, iLO reset itself for the changes to take affect. Here is how you can do it.

1. From the main screen of iLO2, click on Administration tab
2. From the left pane, click on Settings. Then click on Network

3. Click on Apply button (No need to change any network settings).
4. Your iLO browser window will be terminated.
5. It may take 30-60 seconds for the iLO to reboot.

This is an offline method,  it means you need to be present in the server room to perform this task. If above said methods fails, then you need to perform this steps.

1. Turn OFF your Server.
2. Disconnect the Power supply unit (PSU) and Power supply cables from server.

5. Wait for 2-3 minutes, connect the Power supply and Power cable back to the server.
