Jeff, Part II :) What looks confusing to me is during boot and the initial device driver loading the Adapter and drive is found, scsi1, and the one drive attached is assigned the /dev device sda. but once the boot sequence is done, there is no /dev/sda or a device reported by /proc/scsi/scsi. -pete "wait till i attach all 14 devices" On Sun, 2005-10-02 at 20:18, Jeff Vian wrote: > On Sun, 2005-10-02 at 19:01 -0700, Pete Lancashire wrote: > > (will update to FC3 soon) > > > > FC1 x86 > > > > I just added an Adaptec 29160 and for now one old hard drive > > > > a snip of dmesg gives me > > > > Attached scsi disk sda at scsi1, channel 0, id 0, lun 0 > > SCSI device sda: 17755614 512-byte hdwr sectors (9091 MB) > > sda: unknown partition table > > > > but no matter what I do, where I look cant find my disk > > like fdisk /dev/sda give unable to open device. > > > > > > /proc/scsi/scsi only has my two pseudo scsi devices in it > > > > Attached devices: > > Host: scsi0 Channel: 00 Id: 00 Lun: 00 > > Vendor: ATAPI Model: CD-RW 52X24X Rev: MB53 > > Type: CD-ROM ANSI SCSI revision: 02 > > Host: scsi0 Channel: 00 Id: 01 Lun: 00 > > Vendor: TOSHIBA Model: CD/DVDW SD-R5372 Rev: TU53 > > Type: CD-ROM ANSI SCSI revision: 02 > > > > > You may want to check/confirm the actual scsi cable is properly > connected and terminated.
