Abstract

LIC-MEDIA-TAPE-WAIT DURING VARY ON

Error Description

If a bus failure occurs during a vary on of a tape device or    
tape library the vary on may go into a long wait and cause other
jobs to wait.                                                  

Problem Summary

If a bus failure occurs during a vary on of a tape device or    
tape library the vary on may go into a long wait and cause other
jobs to wait.                                                  
                                                               
A vary on of a drive in a library in sequential mode fails with
MSGCPD2616 RC3404 if it was previously attached in random mode  
during the current IPL of the LPAR.                            

Problem Conclusion

The code has been changed to prevent this long wait.            
                                                               
The code has been changed to allow a drive that was in random  
mode to be varied on after the tape library has been switched to
sequential mode.
