Hi All
Well, this is not a definitive guide, but it may well help someone else
in future.
First, below is an excellent missive from Scott Mickey who as well as
some good references, gives a history of the A3500 and A1000, which are
of the same family. I found the A1000 reset to work just fine with a
single drive which had not been near to an A1000 and put in slot 0, then
powerup. This creates a single LUN which RSM sees straight away.
The A3500FC was somewhat more difficult to sort out and to be honest I
am not 100% sure what solved my problem.
The most crucial part is to get it working with a HVD SCSI interface
first as though it is a 3500 and ignore the FC channel altogether. When
you can see a disk LUN with probe scsi, then go for the fibre and it
should work fine.
So with the system atatched via SCSI, probe-scsi-all starts to show what
LUNs you have. You need to have a deafult LUN 0 which is defined as a
disk. I managed to achieve this by putting disks which had been
initialised on a A1000 into the 3500/D1000 chassis and it picked up some
disk info. This then allowed me to add other disks and eventually get to
a setup that I wanted.
The real solution is to use the serial port, but this is only for Sun
engineers, so not really an option for us.
Sorry for the waffle, but it was a bit of a painful affair with no clear
route to getting RSM to see it. After that it was plain sailing.
Hope this helps
Peter

Peter Stokes,
Here is an old Sun infodoc that someone put online:
http://www.3113.com/dave/sun/a1000-reset.txt
The A1000 and A3500 have similar controllers and the last
part of this doc covers A3000/A3500/A3500FC reset.
The key is having a serial cable. The unit's serial port
is a DB15 connector (unlike standard serial ports that are
DB9 or DB25). I have not found the pin-out for this serial
cable online and have not had time to sit down and figure out
the pin-out myself by trial-and-error. If you figure out a
working pin-out for this cable, please post it in your
summary. The SunManagers archive has info on how to reset
an A1000 using a serial cable. The A3500FC should be similar.
The D1000/A1000/A3000/A3500/A3500FC came from a NEC plant in
Wichita, Kansas as far as I can tell. The history goes like
this: NCR Wichita plant -> sold to AT&T -> sold to Hyundai
and renamed Symbios Logic -> sold to LSI Logic and renamed
LSI Logic Storage Systems. The result is that data for these
units is spread out over several companies, not just at Sun.
The plant in Kansas reportedly "now designs and manufactures
RAID products - chips, boards, and subsystems up to multiple
terabytes in size". The Sun A3500 = NCR 6285 = Symbios 3621,
or the 6285-3621 controller. There is a little info at NEC:
www.ncr.com/support/support_drivers_patches.asp?Class=pc_library_raid
This is older software (1996-2001) and I'm not sure what is
specific to the A3500FC, so use caution. However, there may
be useful software tools here not available from Sun.
Also:
http://www.info.ncr.com/Teradata/eTeradata-BrowseBy.cfm?page=Hardware%20Platform
On this page, click the "Hardware - RAID" link and then
click on:
"NCR Deskside Modular Arrays Product and Site Preparation Guide"
This will download document 5605-124A.pdf
This is a very interesting doc, as it shows deskside D1000's
and A3000/A3500 controllers + other configurations and
components never offered by Sun. Look for the NCR 6285
controller in this doc. -It explains why the fan between
the two A3500FC power supplies has no guard to prevent
little screws and other debris from falling into the works.
The 6285 (A3x00) was designed to be mounted on edge, not
horizontally, as Sun did by rackmounting it. With the
controller set on edge, debris would not normally fall into
the fan. However with it horizontal, you have to be careful
not to accidentally drop something into the fan and choke the
unit. Good luck resetting your A3500FC. Once you have it
responding, there are some useful docs here:

Hi All
Pretty frustrated here trying to setup an A3500FC.
I have tried on two separate systems with both 2.6 and 9 Solaris.
I have loaded the O/S (either 2.6 5/98 or Sol 9)
Added patches from patch matrix.
My Fibre card (FC100/P) works fine with A5000 and the A3500FC has an ID
of 5 when viewed from a PC which has a Qlogic card in it.
When I load RSM 6.22.1 it loads ok, except it reports it cannot find any
arrays.
eg
drvconfig: driver failed to attach: ssd
drvconfig: driver failed to attach: rdriver
drvconfig: driver failed to attach: rdriver
RDAC daemons initiated
WARNING: set_drivers: No arrays were found that are controlled by either
the sd
or the ssd driver
Can someone please put me out of my misery as to where to go from here
as I have been trying to get this sorted for a while!!
Also how can I verify if the FC100 can see the array controller or not?
Thanks
Peter
