fmadm(1M) System Administration Commands fmadm(1M)NAMEfmadm - fault management configuration tool
SYNOPSISfmadm [-q] [subcommand [arguments]]
DESCRIPTION
The fmadm utility can be used by administrators and service personnel
to view and modify system configuration parameters maintained by the
Solaris Fault Manager, fmd(1M). fmd receives telemetry information
relating to problems detected by the system software, diagnoses these
problems, and initiates proactive self-healing activities such as dis‐
abling faulty components.
fmadm can be used to:
o view the set of diagnosis engines and agents that are cur‐
rently participating in fault management,
o view the list of system components that have been diagnosed
as faulty, and
o perform administrative tasks related to these entities.
The Fault Manager attempts to automate as many activities as possible,
so use of fmadm is typically not required. When the Fault Manager needs
help from a human administrator, service repair technician, or Sun, it
produces a message indicating its needs. It also refers you to a knowl‐
edge article on Sun's web site, http://www.sun.com/msg/. The web site
might ask you to use fmadm or one of the other fault management utili‐
ties to gather more information or perform additional tasks. The docu‐
mentation for fmd(1M), fmdump(1M), and fmstat(1M) describe more about
tools to observe fault management activities.
The fmadm utility requires the user to possess the SYS_CONFIG privi‐
lege. Refer to the for more information about how to configure Solaris
privileges. The fmadm load subcommand requires that the user possess
all privileges.
SUBCOMMANDS
fmadm accepts the following subcommands. Some of the subcommands
accept or require additional options and operands. The load, unload,
reset, and rotate subcommands are intended for trained technical per‐
sonnel. We recommend against use of these subcommands without the spe‐
cific guidance of, for example, a Knowledge Base article.
fmadm acquit fmri | label [uuid]
Notify the Fault Manager that the specified resource is not to be
considered to be a suspect in the fault event identified by uuid,
or if no UUID is specified, then in any fault or faults that have
been detected. The fmadm acquit subcommand should be used only at
the direction of a documented Sun repair procedure. Administrators
might need to apply additional commands to re-enable a previously
faulted resource.
fmadm acquit uuid
Notify the Fault Manager that the fault event identified by uuid
can be safely ignored. The fmadm acquit subcommand should be used
only at the direction of a documented Sun repair procedure. Admin‐
istrators might need to apply additional commands to re-enable any
previously faulted resources.
fmadm config
Display the configuration of the Fault Manager itself, including
the module name, version, and description of each component module.
Fault Manager modules provide services such as automated diagnosis,
self-healing, and messaging for hardware and software present on
the system.
fmadm faulty [-afgiprsv] [-n max] [-u uid]
Display status information for resources that the Fault Manager
currently believes to be faulty.
The following options are supported:
-a Display all faults. By default, the fmadm faulty command
only lists output for resources that are currently
present and faulty. If you specify the -a option, all
resource information cached by the Fault Manager is
listed, including faults which have been automatically
corrected or where no recovery action is needed. The
listing includes information for resources that might no
longer be present in the system.
-f Display faulty fru's (Field replaceable units).
-g Group together faults which have the same fru, class and
fault message.
-i Display persistent cache identifier for each resource in
the Fault Manager.
-n max If faults or resources are grouped together with the -a
or -g options, limit the output to max entries.
-p Pipe output through pager with form feed between each
fault.
-r Display Fault Management Resource with their Identifier
(FMRI) and their fault management state.
-s Display 1 line fault summary for each fault event.
-u uid Only display fault with given uid.
-v Display full output.
The percentage certainty is displayed if a fault has multiple sus‐
pects, either of different classes or on different fru's. If more
than one resource is on the same fru and it is not 100% certain
that the fault is associated with the fru, the maximum percentage
certainty of the possible suspects on the fru is displayed.
The Fault Manager associates the following states with every resource
for which telemetry information has been received:
ok
The resource is present and in use and has no known problems so far
as the Fault Manager is concerned.
unknown
The resource is not present or not usable but has no known prob‐
lems. This might indicate the resource has been disabled or decon‐
figured by an administrator. Consult appropriate management tools
for more information.
faulted
The resource is present but is not usable because one or more prob‐
lems have been diagnosed by the Fault Manager. The resource has
been disabled to prevent further damage to the system.
degraded
The resource is present and usable, but one or more problems have
been diagnosed in the resource by the Fault Manager.
If all affected resources are in the same state, this is reflected
in the message at the end of the list. Otherwise the state is given
after each affected resource.
fmadm flush fmri
Flush the information cached by the Fault Manager for the specified
resource, named by its FMRI. This subcommand should only be used
when indicated by a documented Sun repair procedure. Typically, the
use of this command is not necessary as the Fault Manager keeps its
cache up-to-date automatically. If a faulty resource is flushed
from the cache, administrators might need to apply additional com‐
mands to enable the specified resource.
fmadm load path
Load the specified Fault Manager module. path must be an absolute
path and must refer to a module present in one of the defined
directories for modules. Typically, the use of this command is not
necessary as the Fault Manager loads modules automatically when
Solaris initially boots or as needed.
fmadm unload module
Unload the specified Fault Manager module. Specify module using the
basename listed in the fmadm config output. Typically, the use of
this command is not necessary as the Fault Manager loads and
unloads modules automatically based on the system configuration
fmadm repaired fmri | label
Notify the Fault Manager that a repair procedure has been carried
out on the specified resource. The fmadm repaired subcommand should
be used only at the direction of a documented Sun repair procedure.
Administrators might need to apply additional commands to re-enable
a previously faulted resource.
fmadm replaced fmri | label
Notify the Fault Manager that the specified resource has been
replaced. This command should be used in those cases where the
Fault Manager is unable to automatically detect the replacement.
The fmadm replaced subcommand should be used only at the direction
of a documented Sun repair procedure. Administrators might need to
apply additional commands to re-enable a previously faulted
resource.
fmadm reset [-s serd] module
Reset the specified Fault Manager module or module subcomponent. If
the -s option is present, the specified Soft Error Rate Discrimina‐
tion (SERD) engine is reset within the module. If the -s option is
not present, the entire module is reset and all persistent state
associated with the module is deleted. The fmadm reset subcommand
should only be used at the direction of a documented Sun repair
procedure. The use of this command is typically not necessary as
the Fault Manager manages its modules automatically.
fmadm rotate errlog | fltlog
The rotate subcommand is a helper command for logadm(1M), so that
logadm can rotate live log files correctly. It is not intended to
be invoked directly. Use one of the following commands to cause the
appropriate logfile to be rotated, if the current one is not zero
in size:
# logadm -p now -s 1b /var/fm/fmd/errlog
# logadm -p now -s 1b /var/fm/fmd/fltlog
OPTIONS
The following options are supported:
-q Set quiet mode. fmadm does not produce messages indicating the
result of successful operations to standard output.
OPERANDS
The following operands are supported:
cmd The name of a subcommand listed in SUBCOMMANDS.
args One or more options or arguments appropriate for the selected
subcommand, as described in SUBCOMMANDS.
EXAMPLES
