sata-nv hotplug feature

[Russ Weeks <rweeks@razorwire.ca>]

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?

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.

Thanks,

Russ
