megaraid: ABORTING problem

[Paul Wagland]

Hi all,

In trying to do some performance analysis on my LSI Login SATA-150-6, I
set it off running bonnie against multiple filesystems against multiple
stripe sizes and RAID levels. Well, all was fine for about three days (I
was running a lot of tests ;-) and then I get back to my machine today
to discover that it was locked up, and the following was on the console:

megaraid: ABORTING-188cf36 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf36[52], fw owner.
megaraid: ABORTING-188cf37 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf37[51], fw owner.
megaraid: ABORTING-188cf38 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf38[37], fw owner.
megaraid: ABORTING-188cf39 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf39[3e], fw owner.
megaraid: ABORTING-188cf3a cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3a[3], fw owner.
megaraid: ABORTING-188cf3b cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3b[65], fw owner.
megaraid: ABORTING-188cf3c cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3c[c], fw owner.
megaraid: ABORTING-188cf3d cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3d[1e], fw owner.
megaraid: ABORTING-188cf3e cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3e[57], fw owner.
megaraid: ABORTING-188cf3f cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf3f[b], fw owner.
megaraid: ABORTING-188cf40 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf40[5d], fw owner.
megaraid: ABORTING-188cf41 cmd=2a <c=0 t=5 l=0>
megaraid: ABORTING-188cf41[5e], fw owner.


Does anyone know what is the cause of this failure?

I can see in the code that this comes out of the
megaraid_abort_and_reset() function, and this is in turn called by
megaraid_abort() and megaraid_reset(). These in turn appear to be called
from the SCSI layer? But why? And why did the machine hang?

Thanks in advance for any help,
Cheers,
Paul

You seem to be running a older version of the driver. Can you upgrade to the
latest 2.10.3 or 2.20.x.x and re-test. Also, what is the firmware version on
this controller.

Ah. Guess I had better get to work adding in sysfs support to the new
unified driver then ;-)

This was the 2.6.4 kernel driver, and from /proc/hba0/config I get:

Version =712T:G116, DRAM = 64Mb

I was running these tests as part of a baseline to see what, if any,
performance differences there would be with the new unified driver.
Should this be fixed in that new driver?

Thanks in advance,
Paul

The new drivers have the new error handling, so your server should still be
operative if commands start to abort.

Please teach me how to build
the latest unified driver(2.20.B1) by 2.6.5.
Is there any update patch from 2.00.3 to 2.20.B1?

1. mkdir -p drivers/scsi/unified/beta
2. Extract the driver files into the directory
3. From that directory, run 
	make -C /usr/src/linux SUBDIRS=$PWD modules

2.20.B1 is a new effort. It doesn't have any incremental
patch from an older driver.
