Hi. This is a new computer that I want to install Linux on, with 3 SCSI
disk drives. No problem with the first. But I'm getting

# fdisk /dev/sdb

Unable to open /dev/sdb

and equivalent messages from cfdisk and sfdisk. They are the latest
util-linux-2.8 versions (2.8, 0.8l and 3.07). Ditto with /dev/sdc.

The kernel was compiled with gcc 2.7.2.1.

The disks are probed okay at boot time:
