I mailed the messages to Justin Gibbs and he told me that the problem is caused by a firmware bug in the Seagate drives. Anoncvs has slightly different drives, but I bet its the same bug: da0 at ahc0 bus 0 target 0 lun 0 da0: <SEAGATE ST39236LW 0004> Fixed Direct Access SCSI-3 device da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da0: 8761MB (17942584 512 byte sectors: 255H 63S/T 1116C) da1 at ahc0 bus 0 target 1 lun 0 da1: <SEAGATE ST39236LW 0004> Fixed Direct Access SCSI-3 device da1: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da1: 8761MB (17942584 512 byte sectors: 255H 63S/T 1116C) You will have to contact Seagate technical support to get the firmware upgrades. But in the meantime, according to Justin, disabling the write caches (WCE in mode page 8) will work around the problem. You can do that with the camcontrol command. Justin posted more details about this in the FreeBSD-scsi mailing list. John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
