Below is a patch to add some hotplug infrastructure to the Linux SCSI
subsystem.

New files:
include/scsi/scsi_hotplug.h
drivers/scsi/scsi_hotplug.c
implements a new exported function:

extern int scsi_topology_hctl_action(struct Scsi_Host *shost, unsigned int channel,
			      unsigned int id, unsigned int lun, enum scsi_topology_action action);

which invokes kobject_hotplug() on a temporary "scsi_topology"
device.  This device represents a target that exists on a topology
(i.e. was just inserted into a hot plug enclosure, or was just created
by a RAID controller management application) but is not yet hooked
into the kernel.

Modified files:
drivers/scsi/Kconfig
drivers/scsi/Makefile
drivers/scsi/megaraid/megaraid_mbox.c
 (will follow in a separate patch)
 is the user of this new function.

In addition, two more infrastructure pieces are necessary:
udev-050-scsi_topology.patch - adds the subsystem name "scsi_topology"
to the list of devices *not* to wait for the creation of files in
sysfs for - scsi_topology devices aren't to be registered in sysfs.

/etc/hotplug/scsi_topology.agent
 handles the hotplug call, and invokes /sys/class/scsi_host/hostX/scan
 and /sys/class/scsi_device/H:C:T:L:/device/delete as appropriate.


The flow is as follows:

# echo "2" > /sys/class/scsi_host/host2/logical_drive_created
(to be done by a management application that knows it just created
logical drive #2 on the controller)

megaraid_mbox.c sysfs method converts logical drive number to HCTL
value, calls scsi_topology_hctl_action().

scsi_topology_hctl_action() invokes kobject_hotplug() with a
scsi_topology subsystem device.

kobject_hotplug() calls /sbin/hotplug or /sbin/udevsend (more likely
the latter), which invokes /etc/hotplug/scsi_topology.agent with the
ACTION={add,remove}.

scsi_topology.agent invokes /sys/class/scsi_host/hostX/scan or
 /sys/class/scsi_device/H:C:T:L:/device/delete as appropriate.

>From this point, we're back into known territory, with the device
being made known, or deleted from, the kernel's view.

Thoughts?

I posted this back in February, with no response (good or bad).
I still think this is useful, and would appreciate feedback.

Thanks,
Matt
