Yes, we see this on Solaris 11.1 too. There seems to be something
seriuosly wrong with the topology information in fmadm for these
systems. Our workaround is to disable these tests all together (there
are numerous other temperature sensors in these systems and disk
errors tend to be noticed by SMART-reporting, so we see not much harm
in this).
Disable this through "/usr/lib/fm/fmd/plugins/disk-transport.conf"
In our configuration management we have the following as default:
[origin /export/itree/info]# cat
files//usr/lib/fm/fmd/plugins/disk-transport.conf/_DEFAULT
#
# Copyright (c) 2007, 2011, Oracle and/or its affiliates. All rights
reserved.
#
# This file allows configuration of the disk-transport functionality. All
# parameters are optional.
# Parameters are set using the syntax:
# setprop <parameter> <value>
#
# Supported parameters are as follows:
#
# The "interval" parameter governs how frequently the transport runs.
Default
# value is one hour (60m).
# setprop interval <time interval>
#
# The "temp-multiple", "selftest-multiple" and "smart-multiple" parameters
# indicate on which multiple of the interval parameter that this
particular test
# runs. Zero (0) prevents the test from executing. Default value is
one (1).
#
# WARNING: Setting multiples to zero (0) is not recommended especially
for the
# smart test as this will prevent the system from detecting and
reporting disk
# errors.
#
# setprop temp-multiple <integer>
# setprop selftest-multiple <integer>
# setprop smart-multiple <integer>
setprop temp-multiple 0
In case fmadm allready disabled your disks, just run:
#for i in `fmadm faulty | grep Major | awk '{ print $4 }'`; do fmadm
acquit $i; done
Good luck!
