Hello.
There are 5 SCSI disks happily running at sda - sde. The 6th
disk is accepted as /dev/sdf, as the kernel output after lilo
says. But fdisk /dev/sdf fails with "Unable to open /dev/sdf".
Other progs as "dd if=/dev/sdf of=/dev/null ..." work neither.
strace fdisk /dev/sdf gives
open("/dev/sdf", O_RDWR) = -1 ENXIO (Device not configured)
open("/dev/sdf", O_RDONLY) = -1 ENXIO (Device not configured)
The physical drive which is expected as sdf sits together with 2
others in a separate external HP-SCSI-box, which is also
terminated externally. All 6 disks are Ultra Wide SCSI. Cabling
is 1.60m at scsi0 (internal bus) and scsi1 (external bus).
What is missing here? Any help much appreciated. Details
follow, thank you.
