Date: Mon, 08 Jul 2002 15:36:07 +0000 Mime-Version: 1.0 Content-Type: text/plain; format=flowed Message-ID: X-OriginalArrivalTime: 08 Jul 2002 15:36:07.0597 (UTC) FILETIME=[2D8CA5D0:01C22695] Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I have an AlphaStation 400 with two SCSI disks, dka0 (da0) and dka100 (da1) running 4.5-STABLE. The first disk, which is the one I boot from, is exhibiting signs of sickness (high-pitched whining isn't good, is it?), so I want to make the box boot from the second one. I read in the Alpha Hardware Notes that, "In order to be bootable the root partition (partition a) must be at offset 0 of the disk drive" (section 2.2). On the second disk, I have da1e, which is at offset 0, but it isn't "partition a". Can I boot from that? I tried copying the necessary stuff (/boot, /etc, /bin, etc.) over and doing "boot dka100" in SRM; that seemed to do what I want (SRM reported that it was indeed booting from dka100), but the root filesystem was still mounted from da0a (as reported by the kernel, "Mounting root from ufs:da0a"; I didn't change fstab to point to da1e, but AFAICT that shouldn't affect where the _kernel_ mounts root from). Is it possible to do what I want (have a system boot from da1e, which is at offset 0)? If not, can I rename da1e to da1a (which I should be able to boot from) without having to newfs it? Thanks in advance, Mike. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
