I did it by reducing the command tags. The default was 255 and I started by just cutting that in half. I kept divi= ding by 2 until I got to 25. At 50 I only had the time outs every few days. At= 25 I have not had an error in over a week. I could possibly increase from 25 = but I won't bother. Performance seems to be fine and the errors are stopped. You can do this with the camcontrol tags command camcontrol tags [dev_id][generic args] [-N tags] [-q] [-v] Here are the steps. camcontrol devlist at scbus0 target 8 lun 0 (pass0,da0) at scbus0 target 9 lun 0 (pass1,da1) at scbus0 target 10 lun 0 (pass2,da2) at scbus0 target 11 lun 0 (pass3,da3) at scbus0 target 12 lun 0 (pass4,da4) at scbus0 target 13 lun 0 (pass5,da5) camcontrol tags da5=20=20=20 (pass5:mps0:0:13:0): device openings: 25 Originally mine was at 255. This can be done on a live system and doesn't require closing the disk and reopening it to take effect. I just changed a= ll 15 hdisks. --=20 You are receiving this mail because: You are the assignee for the bug.=
