SCSI Error with mly
Massimo Lusetti
I got this errors on my 'kernel logs' mail message:
---
> mly0: physical device 0:0 sense data received
> mly0: sense key 3 asc 03 ascq 00
> mly0: info 01c04c4b csi 00000000

I use a:
---
mly0: <Mylex AcceleRAID 170> mem 0xfbffe000-0xfbffffff irq 9 at device 10.1 on
pci0
mly0: AcceleRAID 170 , 1 channel, firmware 6.00-13-00 (20010911), 32MB RAM
---
on a 4.4-STABLE box.
If i've understand correctly what's the meaning of that kernel message it
is "MEDIUM ERROR", but what really "MEDIUM ERROR" means ?! My hd is leaving
me ?! I've to get worried about that !?
I've also noted that sys/cam/scsi/scsi_all.c was updated 9 days ago since
August so do ou suggest a cvsupdate ?!

It would be interesting what asc 0x3 means.
But obviously your disk is failing - you should replace it.
It may also be some power supply isue.

From the description Rev 1.28 should eliminate command errors, which is
different from what you see.

Where did you find this info, i would like to learn more.

The tool is something I wrote for Legato years ago.
The documentation can be found in the SCSI-2 and other specs
at http://www.t10.org.
You can also find stuff somewhere down in the bowels of CAM in
sys/cam/scsi/scsi_all.?
I asked Mike why the mly driver didn't use the printout routines in CAM, and
he had the very reasonable answer of "didn't know they were there"- no
documentation means people can miss stuff.

Well, looking at sys/cam/scsi/scsi_all.c

/* DTL W SO */{SST(0x03, 0x00, SS_DEF,
"Peripheral device write fault") },

You were right, thanks for the hint.
Now i'm quite convinced my drives is leaving me :[ also if i've had 'only' five
errors in a day from it.

Completely agree.
There's a plan to implement an interface for the mly(4) driver to control at
runtime the operation of that controller ?
I've seen Mylex porting some stuff to the Linux world...

No clue as to this latter. Ask the author.
