Hi,   
  
When I run amcheck with chg-scsi, I've got the following message:

All of my tapes are labeled and here is my chg-scsi.conf file  
  
number_configs  1  
eject           0         
sleep           5

enduse          9

cleancart       57                
cleanfile       /usr/pkg/etc/amanda/backup/changer-scsi/tape0-clean   
usagecount      /usr/pkg/etc/amanda/backup/changer-scsi/totaltime  
 
I have defined tapetype in amanda.conf as follows: 
 
define tapetype Fujitsu { 
    comment "Fujitsu tape" 
    length 200gbytes 
    filemark 100kbytes 
    speed 100 kbytes 
} 
 
I don't know why I got that problem. The chg-scsi.debug file (see the attached) 
doesn't give me any clue. I would appreciate if anyone could help me to resolve 
it.   
Thank you,
