Hello,
I have a question about this transport layer and SAS Hot plugging.
With a LSI1068 (SAS) card, I'm trying to do device hotplug.
Back in the day I used the /proc calls below to hotplug a device.
scsi remove-single-device <args>
scsi add_single-device <args>
With 2.6.16-1 kernel, the "remove" call below works, the /dev/sd*
structure is removed.
echo scsi remove-single-device 0 07 00 00 > /proc/scsi/scsi
However, this does not add the device back (the /dev/sd* node
is not created):
echo scsi add-single-device 0 07 00 00 > /proc/scsi/scsi
I see the scsi_proc.c to scsi_transport_sas.c user_scan transport
layer code and it seems hooked up properly. Before I debug, has
anyone else seen a problem here?
Thanks for any help,
-Scott.
