Re: Trouble with a Adaptec 2010S RAID PCI adapter

Salyzn tks for the info. Following it I found the thread:  [patch 1/1] 
Get I2O working with Adaptec's zero channel controllers, 
(http://groups.google.com/groups?q=2010s+group:mlist.linux.scsi&hl=en&lr=&ie=UTF-8&group=mlist.linux.scsi&selm=linux.scsi.200405290713.i4T7Dxr25622%40mail.osdl.org&rnum=1) 
  where the patch is posted. The thread is really unanswered and the 
patch is the same from  http://i2o.shadowconnect.com where it is called 
i2o-adaptec-zerochannel-support.patch

I already had it applied to my kernel and couldn't make the adapter work.

I'll have a look on dpt_i2o...

Anyway, my results are that this patch is not working for a Adaptec 
2010S card. I'm copying Mr Andrew Morton who first posted the patch so 
he gets aware of it. (sorry if you get it doubled, I don't know if you 
are at linux-raid).

tks for your attention...

The 2010 Adapter is a Zero Channel RAID card that does *not* purely
follow the I2O standard. It separates out the message unit from the
message pool, each having its own Base Address register (BAR) rather
than a single unifying BAR.

There were recent patches to the I2O layer to support this adapter
posted to the linux-scsi list. Pick them up and check them out. I
believe that there are still problems with that code.

The dpt_i2o driver, which supports 64 bit operation, continues to
properly support this adapter in the 2.6 tree, and updates to this
driver were also posted to the linux-scsi list w/o feedback (so in, not
in, don't know).

Subject: Trouble with a Adaptec 2010S RAID PCI adapter


Hi list, I'm in trouble trying to use a Adaptec 2010S RAID PCI adapter
in a i386 linux box running kernel 2.6.6. I've enabled I2O in the kernel

and support for my SCSI adapter, that in fact works fine.

CONFIG_I2O=y
CONFIG_I2O_CONFIG=y
CONFIG_I2O_BLOCK=y
CONFIG_I2O_SCSI=y
CONFIG_I2O_PROC=y

My dmesg shows something like this:

...<snip>...
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36

It seens that the kernel has found the controoler. Then I headed to
http://i2o.shadowconnect.com/  - I2O on Linux Home and got their
raidutil package. But here starts the problem, even simple commands like

raidutil -L controller

gives me the error:

Engine connect failed: COMPATIBILITY number
osdIOrequest : File /dev/dpti17 Could Not Be Opened


Following the site info I have applied the following patchs to my
kernel:

i2o-64-bit-fix.patch
i2o-adaptec-zerochannel-support.patch
i2o-config-clean.patch
i2o-makefile-cleanup.patch
i2o-pae-support.patch
i2o-passthru.patch
i2o_block-cleanup.patch
i2o_cmd_passthru-reorder.patch
i2o_config-checking-bugfix.patch
i2o_proc-full-seq_file.patch
i2o_proc-lct-access-bugfix.patch

with no luck. I've tried Adaptec's asmbe_linux_v1.23.006.tgz tools, but
aaccli cannot find the controller as well.

Does anybody experienced a problem like this before? I've found some
messages on mailling lists with the same error message, but no
solutions. I'm new to I2O. Am I missing something?

tks in advance for any help.

Andre
