Hello, My SCSI ZIP drive does not always get probed correctly at initial boot, and *never* if there is no ZIP inserted. This is on 3.1-STABLE as of March 22nd. I have an ncr810 is the first scsi-bus, with two disks and a CD, and an aha1542B is the second bus, with an external ZIP and sometimes a scanner. Cables are almost new, hopefully not of too crappy quality. And the same hardware worked with 2.2.8 (w/o CAM). Dmesg output for the Adaptec controller looks like: aha0 at 0x330-0x333 irq 9 drq 6 on isa aha0: AHA-1540/1542 64 head BIOS FW Rev. 1.2 (ID=41) SCSI Host Adapter, SCSI ID 7, 16 CCBs [...] (da2:aha0:0:5:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0 (da2:aha0:0:5:0): error code 0 (da2:aha0:0:5:0): fatal error, failed to attach to device (da2:aha0:0:5:0): lost device (da2:aha0:0:5:0): removing device entry So, I think I can locate the place in scsi_da.c where this comes from, but then what... :( A "camcontrol rescan 1" will locate the drive, as will rebooting with a ZIP inside. Anybody else seeing this? Hints, suggestions or patches are welcome. BTW: Is there any way to get CAM to attach a device, other than pass<N>, to a device after boot? /Mikko Mikko Tyo"la"ja"rvi________________________________mikko@securitydynamics.com SecurityDynamics To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
