The OAM display lost volumes command displays the volume serial numbers of the optical and tape volumes that have LOSTFLAG set. OAM requests might fail if this flag is set. This command allows you to determine which volumes are "lost" and to perform the necessary troubleshooting on those volumes.

The following command syntax displays the optical and tape volumes that have LOSTFLAG set:

LOSTVOL
Displays the optical and tape volumes that have LOSTFLAG set.

To display the optical and tape volumes that have LOSTFLAG set, enter the following command:

F OAM,DISPLAY,LOSTVOL

The output of the F OAM,DISPLAY,LOSTVOL command shows optical volumes that are lost, but no tape volumes that are lost:

   F OAM,DISPLAY,LOSTVOL                                        
   CBR1154I OPTICAL volume OPTVOL1 is a lost volume.            
   CBR1154I OPTICAL volume OPTVOL2 is a lost volume.            
   CBR1155I Total number of OPTICAL volumes marked lost is 2.   
   CBR1155I Total number of TAPE volumes marked lost is 0. 

The output of the F OAM,DISPLAY,LOSTVOL command shows both optical and object tape volumes that are lost:

   F OAM,DISPLAY,LOSTVOL                                       
   CBR1154I OPTICAL volume OPTVOL1 is a lost volume.           
   CBR1154I OPTICAL volume OPTVOL2 is a lost volume.           
   CBR1155I Total number of OPTICAL volumes marked lost is 2.  
   CBR1154I TAPE volume TAPEVOL1 is a lost volume.              
   CBR1155I Total number of TAPE volumes marked lost is 1.     
To clear the status of a lost volume, use either of the following commands:
F OAM,UPDATE,VOLUME,VOLSER,LOSTFLAG,OFF
or the
F OAM,RESTART
