Hi, First off, please let me know if I should repost this to a support mailing list. Or, if the answer is 'rtfm', please just point me to the manual. I checked the libata FAQ but can't find what I need. I'd like some more information regarding the device hotplug feature for the sata-nv driver. The FAQ indicates that 'device hotplug' == 'yank the drive': this seems more like 'hot-unplug' to me. Can I then plug the drive back in after I've unplugged it? This thread: http://www.mail-archive.com/ubuntu-server@xxxxxxxxxxxxxxxx/msg00182.html Seems to indicate that I can do it, but I may need to refresh the SCSI device system somehow. This suits my needs just fine, as long as a plug doesn't necessitate a reboot. But running rescan-scsi-bus.sh doesn't seem to work. uname -a: Linux backfire 2.6.19.2-smp #2 SMP Sat Mar 3 13:06:28 PST 2007 x86_64 x86_64 x86_64 GNU/Linux lspci shows this: 00:06.0 IDE interface: nVidia Corporation CK804 IDE (rev f2) 00:07.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev f3) 00:08.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev f3) lsmod shows that libata and sata-nv are present. rescan-scsi-bus.sh shows this (after I boot with 1 drive plugged in and then try to plug in the other 2): OLD: Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST3250824AS Rev: 3.AA Type: Direct-Access ANSI SCSI revision: 05 (this seems correct, just that 2 other drives are missing) The hardware is a Tyan Thunder K8W 2895 motherboard with an onboard controller. 3 250Gb Seagate Barracudas are attached, 2 are in removable drive trays made by some company called 'ByteCC'. _Any_ advice is appreciated. I'm really in the dark here.
