Hi Gary,I know what you mean by "hijacking a thread" now. I was reading that message when I decided to post my question from the same window. Today I cleared the tape drive with an official cleaning cartridge but it made no difference to the error: ------------------------------------------------------------------------- sg_raw -o - -r 1024 -t 60 -v /dev/sg1 8c 00 00 00 00 00 00 00 00 00 00 00 04 00 00 00 cdb to send: [8c 00 00 00 00 00 00 00 00 00 00 00 04 00 00 00] SCSI Status: Check Condition Sense Information: Fixed format, current; Sense key: Illegal Request Additional sense: Invalid command operation code Raw sense data (in hex), sb_len=21, embedded_len=21 70 00 05 00 00 00 00 0d 00 00 00 00 20 00 00 00 00 00 00 00 00 Error 9 occurred, no data received Illegal request, Invalid opcode ------------------------------------

If it was some kind of a hardware fault I should be seeing other problems, shouldn't I? All backups and Bacula scripts keep completing without errors, it's just this one command that fails. I've even run a big restore as a test and it all looks perfectly fine. I don't have any spare hardware try different configuration. Is there anything else to try to determine the root cause? Why would a reboot alone trigger it? Regards, Adam
Hello Adam,Not sure if this will be any help at all, but I just checked and see that in my `mtx-changer-python.py` drop-in replacement script, to check for tape cleaning required messages, I am using:
----8<---- sg_logs --page=0xc /dev/sg## ----8<---- Then I look for: ----8<---- Cleaning action not required (or completed) or Cleaning action required ----8<---- To determine if I need to automatically find and load a cleaning tape before returning contr ol to the SD...I had been using `tapealert` instead of sg_logs, but I found that tapeinfo clears all alert messages on the drive, so they could never be caught by the SD when it calls tapeinfo in the tapealert script. Sg_logs just reports what I need without clearing the other flags that the SD needs to know when a drive or tape is bad/damaged, etc.
