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).

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 <Adaptec 2940 Ultra2 SCSI adapter> aic7890/91: Ultra2 Wide Channel A, SCSI Id=7, 32/253 SCBs ...<snip>...

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
