I posted about this a few days ago and its appeared again
in my security log (the backup routine log appears to be
fine)

+(sa0:ahc0:0:6:0): PREVENT ALLOW MEDIUM REMOVAL. CDB: 1e 0 0 0 0 0 
+(sa0:ahc0:0:6:0): CAM Status: SCSI Status Error
+(sa0:ahc0:0:6:0): SCSI Status: Check Condition
+(sa0:ahc0:0:6:0): UNIT ATTENTION asc:28,0
+(sa0:ahc0:0:6:0): Not ready to ready change, medium may have changed
+(sa0:ahc0:0:6:0): Unretryable error

I have googled about and there is some suggestion that a
change of tape may cure this ie using DDS4 tapes rather
than DDS3 in a DDS4 drive. I also read about "Vendor
Specific ASCQ" but it was beyond me. I am going to leave
the same tape in and see if its repeated at tonites backup.

If this isnt something serious I will ignore it and go
away however I am curious and would really like to know
why :) (never stop asking...there are no stupid questions etc)

Thanks in advance :)
