[ANNOUNCE 2/2] Serial Attached SCSI (SAS) support for the Linux kernel

[Luben Tuikov]

Using the User Space Expander configuration utility
===================================================

The file "expander_conf.c" is a user space program
which uses the "smp_portal" SMP portal to communicate
with expanders in the domain.

It gives you complete control of the expander you're
talking to, so please be careful if you're changing
route tables, phy settings, etc.

The "expander_conf.c" file is located here:
drivers/scsi/sas-class/expander_conf.c

How it works can be found in
drivers/scsi/sas-class/README, and of course in the
source code.

Here we show complete information about the three
expanders we saw in the previous email.

Dumping configuration info for Expander A
-----------------------------------------

A) As you can see phys 11, 10, 9 and 8 of this expander
are connected to phys 4, 5, 7, and 6 of the Host Adapter,
thus forming a wide port.

This is also the subtractive boundary of this
edge expander device set and of this expander.

B) As you can see phys 7 and 6 of this expander are
connected to phys 8 and 9 of expander B, thus forming
a wide port.

They use table routing attributes.

C) The routing table is also printed for phys 7 and 6.
It is of course identical.

D) End devices attached are clearly identifiable.

Dumping configuration info for Expander C
-----------------------------------------

A) As you can see phys 7 and 3 of this expander are
connected to phys 3 and 2 of Expander B, thus forming
a wide port. This forms the subtractive boundary
of this expander.

B) End devices attached are clearly identifiable.
