H135914 - SYSTEM HANG PERFORMING MULTIPLE XCOPY ROUTINES IN OS/2             
                                                                                
                                                                                
                                                                                
 SYMPTOM:                                                                       
 IBM PC 700 Series 6875 or 6885 systems may exhibit a system                    
 hang condition while multiple sessions in OS/2 WARP 3.x are                    
 simultaneously using the XCOPY command to copy files from one                  
 directory to another on a SCSI hardfile.                                       
                                                                                
 PROBLEM ISOLATION AIDS:                                                        
 When the failure occurs, the system must be powered off/on                     
 to recover.                                                                    
                                                                                
 IDE hardfiles are not affected.                                                
                                                                                
 Failure analysis indicated that the failure is more likely to                  
 occur on older, low capacity SCSI hardfiles such as 360MB                      
 drives.                                                                        
                                                                                
 FIX:                                                                           
 Use following two steps to eliminate this failure from                         
 occurring:                                                                     
                                                                                
 1) Change the following statement in the OS/2 WARP CONFIG.SYS                  
    file if present:                                                            
          change from: BASEDEV=aic7870.add                                      
          change to:   BASEDEV=aic7870.add /A:0 /TAG:1                          
                                                                                
 2) Verify that the SCSI devices are properly terminated.                       
    Consult the users guide for the SCSI adapter and/or devices                 
    for proper termination procedures.                                          
                                                                                
 If the failure persists, continue normal problem determination                 
 to isolate the failing FRU or application.
