          MVS/XA Operating System Information & Troubleshooting       
          -----------------------------------------------------       
                                                                        
    Here are some commands to use when the customer has trouble with    
Hydra-II running under VTAM on an MVS/XA System:                        
                                                                        
D M,CHP=4C - This command will display all devices on the MVS Channel   
             path (4C). Since many devices can be assigned to a pseudo  
             channel path there may be a chance that the hydra is not   
             genned into the system correctly.                          
                                                                        
D U,,,0C0,16 -Will tell you whether the device is online of offline and
              will also display the VTAM ownership                      
                                                                        
D U,,ALOC,0C0,16 - Will tell you which devices are allocated for use.
