9 fmd \- fault manager daemon
13 \fB/usr/lib/fm/fmd/fmd\fR [\fB-V\fR] [\fB-f\fR \fIfile\fR] [\fB-o\fR \fIopt\fR=\fIval\fR] [\fB-R\fR \fIdir\fR]
19 \fBfmd\fR is a daemon that runs in the background on each system.
20 \fBfmd\fR receives telemetry information relating to problems detected by the
21 system software, diagnoses these problems, and initiates proactive self-healing
22 activities such as disabling faulty components. When appropriate, the fault
23 manager also sends a message to the \fBsyslogd\fR(1M) service to notify an
24 administrator that a problem has been detected. The message directs
25 administrators to a knowledge article on http://illumos.org/msg/, which
26 explains more about the problem impact and appropriate responses.
29 Each problem diagnosed by the fault manager is assigned a Universal Unique
30 Identifier (\fBUUID\fR). The \fBUUID\fR uniquely identifes this particular
31 problem across any set of systems. The \fBfmdump\fR(1M) utility can be used to
32 view the list of problems diagnosed by the fault manager, along with their
33 \fBUUID\fRs and knowledge article message identifiers. The \fBfmadm\fR(1M)
34 utility can be used to view the resources on the system believed to be faulty.
35 The \fBfmstat\fR(1M) utility can be used to report statistics kept by the fault
36 manager. The fault manager is started automatically when the operating system
37 boots, so it is not necessary to use the \fBfmd\fR command directly.
41 The following options are supported
45 \fB\fB-f\fR \fIfile\fR\fR
48 Read the specified configuration \fIfile\fR prior to searching for any of the
49 default fault manager configuration files.
55 \fB\fB-o\fR \fIopt\fR\fB=\fR\fIvalue\fR\fR
58 Set the specified fault manager option to the specified value. Fault manager
59 options are currently a Private interface; see \fBattributes\fR(5) for
60 information about Private interfaces.
66 \fB\fB-R\fR \fIdir\fR\fR
69 Use the specified root directory for all pathnames evaluated by the fault
70 manager, instead of the default root (\fB/\fR).
79 Print the fault manager's version to stdout and exit.
85 The following exit values are returned:
101 An error occurred which prevented the fault manager from initializing, such as
102 failure to open the telemetry transport.
111 Invalid command-line options were specified.
118 \fB\fB/etc/fm/fmd\fR \fR

127 \fB\fB/usr/lib/fm/fmd\fR \fR

169 The Fault Manager is managed by the service management facility, \fBsmf\fR(5),
170 under the service identifier:
174 svc:/system/fmd:default
181 The service's status can be queried using the \fBsvcs\fR(1) command.
182 Administrators should not disable the Fault Manager service.
