Fw: 2.6.9-rc2-mm2: 3ware card info not in /proc/scsi

Did this get broken?

Subject: 2.6.9-rc2-mm2: 3ware card info not in /proc/scsi


I have a 3Ware-7500 series card.  I was trying the 2.6.9-rc2-mm2 kernel
and discovered that the 3dmd utility was not working.  A little poking
around revealed that the cause was because the 3Ware directory was not
in /proc/scsi, even though I have CONFIG_SCSI_PROC_FS=y in my config
file.  The 3dmd utility works fine with mainline 2.6.9-rc2 and it worked
with the 2.6.8-mm series of kernels.  Those kernels have a 3w-xxxx
directory in /proc/scsi.

Thanks.

The changelog says it was deliberate:

ChangeSet 1.2212 2004/09/10 17:48:45 aradford@amcc.com
  [PATCH] 3ware 5/6/7/8000 driver v1.26.02.000
  
  - Remove deprecated SCSI_IOCTL_SEND_COMMAND interface.
  - Remove deprecated /proc/scsi/3w-xxxx interface.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  - Convert entire driver to pci_driver format.
  - Remove all mdelays, replace w/msleep to fix possible watchdog
    timer issues.
  - Make all register accesses macros.
  - Remove all prototypes from header file, reorder functions to
    eliminate all prototypes but one.
  - Add sysfs 'queue_depth' setting attribute.
  - Add sysfs 'stats' attribute.
  - Fix spinlocks everywhere, remove tw_lock spinlock.
  - Remove all bitfields, add bitmask access macros.
  - Remove un-needed scsi_eh_abort entrypoint.  Controller does not
    support aborting invididual IO's, scsi_eh_reset sufficient.

I presume there's an updated utility from amcc somewhere that uses the
new sysfs interface.

... and there goes smartmontools support until v5.34 is
released.

More generally (not just 3ware), several smartmontools
users have complained to me about the warnings sent to
their log every time smartd wakes up (30 minutes) and
checks their SCSI disks in recent 2.6 versions. One
deprecated warning should be sufficient.

 From an application maintainer's point of view sysfs is
relatively new (only in lk 2.6) and just starting to settle
down.

You need to update 3Ware tools using "engeneering phase software" at :
