Device removal does not generate hotplug events

Device removal does not generate hotplug events

[Sabharwal, Atul]

I have a Linux system running 2.6.3 kernel, udev v 22.  I have an array
of Qlogic
Disk array which shows up as a SCSI device to the kernel.

Now, when I do virtual insertion/deletion of devices, rules get called
and
Device entries get created/deleted.  ( using sysfs interface to delete
or
Scan new devices ).

Now, when I do physical insertion/deletions, the deletions do not work.
The sysfs
Sub-system still shows the device under /sys although the device has
been physically
Removed.  

Is this a known issue ?  Could this be driver related or a bug in the
SCSI subsystem ?
Subsequent insertion of devices work correctly. So, it's the device
removal which 
Has the problem.

Thanks,

Then this is a scsi kernel issue with your hardware.  I suggest you ask
this on the linux-scsi mailing list.

good luck,
