Generate a Nonmaskable Interrupt

Before You Begin

Obtain permission from Oracle Services prior to performing this procedure.
To generate an NMI from the Oracle ILOM interfaces, you need the Reset and Host Control (r) role enabled.
The setting for generating a nonmaskable interrupt from Oracle ILOM might not be supported on all Oracle servers.

Caution:

Depending on the host OS configuration, generating a nonmaskable interrupt (NMI) might cause the OS to crash, stop responding, or wait for external debugger input.

To generate a processor interrupt, do one of the following:
- From the Oracle ILOM web interface:
  1. Click Host Management > Diagnostics.
    
    The Diagnostics page appears.
  2. Click the Generate NMI button.
    
    An NMI is sent to the host.
- From the Oracle ILOM CLI, type:
  
  set /HOST/diag generate_host_nmi=true
  
  For example:
```
-> set generate_host_nmi=true
set ???generate_host_nmi' to ???true'
```
  An NMI is sent to the host.
