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 :)
