Hi folks I met this message again and again when running a aix7xxx with a HP lTO3 drive. i add some debug msg in my code and i found that this is what i executed. May 24 05:09:21 bridge2scsi kernel: raw_execute_cmnd(102) ENTER raw_execute_cmnd with command 0x8 May 24 05:09:21 bridge2scsi kernel: raw_execute_cmnd(102) ENTER raw_execute_cmnd with command 0x11 May 24 05:09:21 bridge2scsi kernel: raw_execute_cmnd(102) ENTER raw_execute_cmnd with command 0x8 May 24 05:09:21 bridge2scsi last message repeated 21 times May 24 05:09:21 bridge2scsi kernel: raw_execute_cmnd(102) ENTER raw_execute_cmnd with command 0x11 a lot of read_6 follow a space_6. i wonder if anybody can explain a bit me on how to read this dump and what possible reasons can lead to this. thanks. ps, i do not think my code abort a command. ming ------------------------------------------------- May 24 05:09:14 bridge2scsi kernel: scsi0:0:3:0: Attempting to queue an ABORT message
