SCSI Tape Log Question

[Graham Bentley]

Although my backup appears to work fine I get this in the
security log ...

+(sa0:ahc0:0:6:0): 16384-byte tape record bigger than supplied buffer
+(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 will try another tape today. Any suggestions as to what could be causing
this ?

Thanks !
