I've just recently brought a FreeBSD install online. Everything is working fine, but now I want to add an additional SCSI disk to my file system. I've been trying to follow the procedures outlined in section 10.5 of the FreeBSD Handbook. Here are my attempts and results: When I try running sysinstall, I go "Configure" and then "Fdisk". After selecting "Fdisk", the following message appears: No disks found! Please verify that your disk controller is being properly probed at boot time. See the Hardware Guide on the Documentation menu for clues on diagnosing this type of problem. I know that the drive in question is detected at boot because the kernel displays information about the disk whenever the system is coming up. When I try running "dd if=/dev/zero of=/dev/rda1 bs=1k count=1", I receive the message "dd: /dev/rda1: Operation not permitted". I thought that maybe I should replace rda1 with da1 because my drive is /dev/da1. When trying to run "dd if=/dev/zero of=/dev/da1 bs=1k count=1" I get the message "dd: /dev/da1: Operation not permitted". If you go to section 10.5.2.2 in the Handbook and then follow either of the two command sequences I get the same results. I also noticed that in the Handbook the commands used use both rda1 and da1. Is that normal? I don't understand why you would use two different device names? As I understood it, the prefix r- is for removable media. Am I wrong? The following is an excerpt from the /var/log/dmesg.today file: ad0: 515MB <WDC AC2540F> [1048/16/63] at ata0-master PIO3 ad1: 1549MB <WDC AC21600H> [3148/16/63] at ata0-slave WDMA2 ad2: 4112MB <WDC AC24300L> [8912/15/63] at ata1-master WDMA2 Waiting 15 seconds for SCSI devices to settle Mounting root from ufs:/dev/ad0s1a da0 at ahc0 bus 0 target 0 lun 0 da0: <IBM DPES-31080 !t S31R> Fixed Direct Access SCSI-2 device da0: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled da0: 1034MB (2118144 512 byte sectors: 255H 63S/T 131C) da1 at ahc0 bus 0 target 1 lun 0 da1: <IBM DPES-31080 !t S31R> Fixed Direct Access SCSI-2 device da1: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled da1: 1034MB (2118144 512 byte sectors: 255H 63S/T 131C) And, yes, I was running sysinstall and the dd commands as root.
