#25 worksforme SCSI pass through for SMART via USB on MacOSX smartmontools? 3rd party code available! cooties putzfetzenorg
Description

Dear smartmontools developers!

Until the very recent version of smartmontools (5.39), SMART through USB was not possible on Mac OS X, because the Mac OS X kernel does not support SCSI pass through (reasoning of Christian Franke).

Meanwhile I googled for: http://www.google.com/search?q=mac+osx+scsi+passthrough+usb

And found a person, who wrote a SCSI pass through driver for Mac OS X: http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html

In the site's comment section I asked as Stefan Nowak whether this code could be used for passing through SMART: http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html#comment-24129787

And the developer answered within the site's comment section as wagerlabs, that it should work: http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html#comment-24130057

I don't know low-level coding, otherwise I would offer my help. Please, dear Darwin related smartmontools developers: Could you built SMART through USB support into the Mac version of smartmontools?

Regards, Stefan Nowak

#121 worksforme smartd fails to report disk failure if a disk doesn't respond anymore Christian Franke kaluscha
Description

I had a self test running on disk hdb:

smartd: Device: /dev/hdb, self-test in progress, 10% remaining

The disk encountered problems, see /var/log/messages:

kernel: hdb: dma_timer_expiry: dma status == 0x61
kernel: hdb: DMA timeout error
kernel: hdb: dma timeout error: status=0xd0 { Busy }
kernel: ide: failed opcode was: unknown
kernel: hda: DMA disabled
kernel: hdb: DMA disabled
kernel: ide0: reset: success

There were several kernel IDE resets until the drive didn't respond anymore:

kernel: hdb: drive not ready for command

smartd wrote messages:

smartd: Device: /dev/hdb, failed to read Temperature

However, smartd had been configured to send e-mails in case of trouble (/dev/hdb -a -I 194 -W 4,40,42 -R 5 -m myamil). In this case, it failed to do so.

In my opinion this is a major problem as smartd should inform the admins that a disk is complety offline, i.,e. doesn't respond to requests on the IDE bus anymore.
