It seems it depends on how the modules are loaded. Yesterday I noticed that when it worked after a reboot I got an sd_mod module : #### rabeson:{root}:/var/log > lsmod Module Size Used by sd_mod 17217 0 sbp2 24076 0 scsi_mod 122445 2 sd_mod,sbp2 ohci1394 35784 0 ieee1394 298228 2 sbp2,ohci1394 which I did'nt see yesterday. Today I could see it after many experiments. I suceeded by loading modules in that order : rmmod sbp2 rmmod sd_mod rmmod scsi_mod rmmod ohci1394 rmmod ieee1394 modprobe -v ohci1394 # load ieee1394 and ohci1394 modprobe -v sbp2 # load scsi_mod and sbp2 modprobe -v sd_mod # load sd_mod but I wonder if the problem commes from the modules, hotplug ... and if I have to config something. > Or do you "lose" the disk if you plug-in/plug-out the firewire disk when > your laptop is running? > If I unplug the disk I losse it: #### rabeson:{root}:/home/users/sbob > cat /proc/scsi/scsi Attached devices: but if I plug it again it reapears : #### rabeson:{root}:/home/users/sbob > cat /proc/scsi/scsi Attached devices: Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: Ext Hard Model: Disk Rev: Type: Direct-Access ANSI SCSI revision: 06 and /var/log/messages says : Sep 22 18:31:17 rabeson kernel: scsi2 : SCSI emulation for IEEE-1394 SBP-2 Devices Sep 22 18:31:18 rabeson kernel: ieee1394: sbp2: Maximum concurrent logins supported: 4 Sep 22 18:31:18 rabeson kernel: ieee1394: sbp2: Number of active logins: 0 Sep 22 18:31:18 rabeson kernel: ieee1394: sbp2: Logged into SBP-2 device Sep 22 18:31:18 rabeson kernel: Vendor: Ext Hard Model: Disk Rev: Sep 22 18:31:18 rabeson kernel: Type: Direct-Access ANSI SCSI revision: 06 Sep 22 18:31:18 rabeson kernel: SCSI device sda: 1953546240 512-byte hdwr sectors (1000216 MB) Sep 22 18:31:18 rabeson kernel: sda: asking for cache data failed Sep 22 18:31:18 rabeson kernel: sda: assuming drive cache: write through Sep 22 18:31:18 rabeson kernel: SCSI device sda: 1953546240 512-byte hdwr sectors (1000216 MB) Sep 22 18:31:18 rabeson kernel: sda: asking for cache data failed Sep 22 18:31:18 rabeson kernel: sda: assuming drive cache: write through Sep 22 18:31:18 rabeson kernel: sda: sda1 Sep 22 18:31:18 rabeson kernel: Attached scsi disk sda at scsi2, channel 0, id 0, lun 0 Sep 22 18:31:18 rabeson scsi.agent[12546]: disk at /devices/pci0000:00/0000:00:1e.0/0000:02:0f.2/fw-host0/0030e002e0606072/0030e002e0606072-0/host2/target2:0:0/2:0:0:0 Thanks for your help. -- Cordialement, Robert FRANCHISSEUR ____ Apollo_gist :-)______________________________________________________ | Robert FRANCHISSEUR - Laboratoire de Météorologie Dynamique - C.N.R.S. | | Equipe "R.A.M.S.E.S." - UNIVERSITE P. et M.
