mptutil(8) segfault on IBM xSeries 3550

[Charles Owens]

Howdy,

We're working with IBM hardware (xSeries 3550) that has an
mpt-based RAID controller... after initial success with testing the
mptutil utility, now operations other than "show adapter" and "show
volume" are resulting in segfaults.

While it was working properly we created and removed volumes several
times, force-failed drives, and just generally put it through its
paces... and all seemed fine.  Then, after a reboot, it suddenly started
failing with segfault as described, and nothing we do has helped to get
it out of this state (including trying to use the LSI in-BIOS manager to
create/delete volumes -- which in and of itself works fine).

We found recent thread
http://docs.freebsd.org/cgi/mid.cgi?4B56CD4C.80503 and hoped that it
might somehow relate... and even tried the patch that John Baldwin
posted, but to no avail.

Has anyone seen this behavior and/or have a suggested fix or workaround?


Here's the output of "mptutil show adapter":

mpt0 Adapter:
       Board Name: SR-BR10i
   Board Assembly: L3-25116-01H
        Chip Name: C1068E
    Chip Revision: UNUSED
      RAID Levels: RAID0, RAID1, RAID1E
    RAID0 Stripes: 64K
   RAID1E Stripes: 64K
 RAID0 Drives/Vol: 1-10
 RAID1 Drives/Vol: 2
RAID1E Drives/Vol: 3-10


This work is being done using FreeBSD 8.0-RELEASE-p2 + PAE.

Thank very much,

Charles
