Access the OpenBoot CLI (Hung System)

Language:

Use this procedure when the system or virtual machine is in a hung state.

This procedure assumes that you performed Identify a Method to Get to the OpenBoot CLI, and you are still logged into Oracle ILOM.

Note - The Oracle ILOM CLI examples in this section are for a single PDomain system. For multiple domain systems, replace /HOST with /HOSTx, where x is the PDomain number.

Temporarily change the auto-boot? parameter to false.
For example:
```
-> set /HOST/bootmode script=”setenv auto-boot? false”
```
This command temporarily prevents the OS from booting before you reach the OpenBoot prompt. This change applies only to a single reset and expires in 10 minutes if the power is not reset.
Reset the system or virtual machine.
For example:
```
-> reset /HOST/domain/control/
```
If the prior step did not work, perform this command to power off the virtual machine, then proceed to Access the OpenBoot CLI (Powered Off).
- Example of stopping a VM in a single PDomain system:
```
-> stop -f /System
```
- Example of stopping a VM in a multiple PDomain system:
```
-> stop -f /HOSTx
```
  Where x is the PDomain number.
