Initiating a stand-alone dump with z/OS virtual server instances

You can initiate a stand-alone dump on the serial console from the IBM Cloud UI. The dump program is placed on the volume DE26 and the target for the dump output is placed on the volume DE2B.

Before you begin

Make sure that you are connected to the z/OS virtual server instance through the serial console and open a new z/OS serial console. For more information, see Getting connected.

The z/OS serial console supports four operands: start, stop, ipl, oprmsg. For more information, see Operating with the serial console.

Procedures

To initiate a stand-alone dump by using the z/OS serial console, you can follow these steps:

Use the tab key to switch between the z/OS serial console and the command line.
To stop control processors, enter stop all, and press Enter.
To start the volume DE2B, enter ipl DE2B, and press Enter.
To initiate a stand-alone dump, enter oprmsg 'device address', and press Enter.
To verify that the stand-alone dump is initiated successfully, see the following message as an example:
```
oprmsg <device address> STAND-ALONE DUMP PROCESSING COMPLETED
