Using the IBM i5/OS tools to work with the temporary and permanent side of the service processor

Learn how to use i5/OS tools to determine which side of the service processor you are booting from.

Note: You should usually be running on the Temporary side.

Issue the following command from the i5/OS^® service partition command line:
```
DSPPTF
```
Record the information that is displayed in the IPL source field. You will need this information later in this procedure if you need to change the boot side. The following is an example of what might appear:
```
                               Display PTF Status                               
                                                             System:   xxxxxxxx
 Product ID  . . . . . . . . . . . . . :   5722999                              
 IPL source  . . . . . . . . . . . . . :   ##MACH#B   ##SERV#T                  
 Release of base option  . . . . . . . :   V5R3M0 L00                          
```
Note the following:
- A value of ##SERV#T indicates the temporary side was used.
- A value of ##SERV#P indicates that the permanent side was used.
Note: If the command does not work, ensure you are on the service partition of an IBM System i5™ or eServer™ i5.
If you need to change the boot side, refer to Switching to the other side of the service processor.
