Antwort: RE: Change the order of scsi Controller
Ok, I use your first solution - great stuff. I had never heared about using disklabel in fstab before. I had wasted to much time with os software from redmond in the past. I have to learn all the new usefull options of linux (not only on alpha). Thank you!

RE: Change the order of scsi Controller
Hi Steffen again, alternatively, you could also use the udev symbolic block device names instead of LABEL=xxx mount points (works also with initramfstools): [EMAIL PROTECTED]:~$ ls -l /dev/disk/by-label/ insgesamt 0 lrwxrwxrwx 1 root root 10 2007-12-01 23:24 boot -> ../../sda2 lrwxrwxrwx 1 root root 10 2007-12-01 23:23 home -> ../../sdb1 lrwxrwxrwx 1 root root 10 2007-12-01 23:23 root -> ../../sdb2 lrwxrwxrwx 1 root root 10 2007-12-01 23:23 swap -> ../../sdb4 lrwxrwxrwx 1 root root 10 2007-12-01 23:23 var -> ../../sdb3 So a kernel command line could be: 0:2/vmlinuz ro initrd=/initrd.img root=/dev/disk/by-label/root - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: [EMAIL PROTECTED] > -Original Message- > From: Uwe Schindler [mailto:[EMAIL PROTECTED] > Sent: Friday, January 18, 2008 9:50 AM > To: [EMAIL PROTECTED]; debian-alpha@lists.debian.org > Subject: RE: Change the order of scsi Controller > > Hi Steffen, > > as Etch uses udev for managing hardware, why not use symbolic names for > your > partitions (based on the file system label)?

RE: Change the order of scsi Controller
Hi Steffen, as Etch uses udev for managing hardware, why not use symbolic names for your partitions (based on the file system label)? This works even in initrd, if you use initramfstools, it does not work with yaird! On my Alphastation I have the following kernel bootlines in aboot.conf: [EMAIL PROTECTED]:/boot$ cat etc/aboot.conf # # aboot default configurations # 0:2/vmlinuz ro initrd=/initrd.img root=LABEL=root 1:2/vmlinuz.old ro initrd=/initrd.img.old root=LABEL=root And the following fstab: [EMAIL PROTECTED]:~$ cat /etc/fstab # /etc/fstab: static file system information. # # proc/proc procdefaults0 0 LABEL=root / ext3defaults,errors=remount-ro 0 0 LABEL=boot /boot ext2defaults,noatime,nodiratime 00 LABEL=var /varext3defaults0 0 LABEL=home /home ext3defaults0 0 LABEL=swap noneswapsw 0 0 The labels were assigned to all partitions e2label and for swap by mkswap. That was it. Works stable and I can change my hardware configuration whatever I like (because sometimes the order changes with every reboot when parallel searching for new devices is enabled). I use this style for all my machines (not only the alpha one). - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: [EMAIL PROTECTED] > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Friday, January 18, 2008 9:13 AM > To: debian-alpha@lists.debian.org > Subject: Change the order of scsi Controller > > Hello, > > I have 2 AlphaServer 4100 (Rawhide) running Debian/Etch and a Digital Raid > Array (RA3000) connected. > > I have installed debian on the Server with the RA3000 switched off running > the generic alphaserver kernel. > > Now everything is installed on /dev/sda: > > /dev/sda3 / ext3 defaults,errors=remount-ro 0 > 1 > /dev/sda2 /boot ext2 defaults0 2 > /dev/sda4 none swap sw 0 0 > > /dev/sda is the first scsi- disk plugged into the local servers SCSI- > Container. > > > Now, if I switch on the raid array and boot the server, the module of the > scsi controller (QLogic qla1280) > has the raid array connected seems to be loaded before the module of the > controller (sym53c8xx) for local disks. > > Thats why my disks order is changed completely. > > The first disk in the raid controller becomes /dev/sda and the disks on > the local controller will be added > after the last disk in the raid array. > > My question is, if the reason for that is really the module- load order > how can I change it easily? > > The scsi- modules are loaded via initrd. > > I already read this article: > > http://ubuntuforums.org/showthread.php?t=219600 > > but my > > /etc/initramfs-tools/module > > file is empty, and I don't know what modules are loaded with initrd. > > Any suggestions? > > PS: > Compiling a new kernel is no optiion for now. > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".
