The Palestinian cause is not a cause for Palestinians only, but a cause for every revolutionary, wherever he is, as a cause of the exploited and oppressed masses in our era.” These are the words of Ghassan Kanafani (1936-1972), a Palestinian author, teacher, revolutionary and a leading member of the Popular Front for the Liberation of Palestine. His journalism and writings were deeply rooted in Arab-Palestinian culture, and inspired a whole generation both during and after his lifetime. On 8 July 1972, he was assassinated by Mossad as a response to the Lod airport massacre although he had played no direct role in this. He was murdered for his commitment to Palestinian resistance and seen by the Israeli occupiers as a threat to the racist occupation regime. His legacy lives on in every Palestinian and internationalist willing to fight for the anti-imperialist cause.

Solaris Fault Manager

Fault Manager is part of self-healing functionality that provides fault isolation and component restart, in this case hardware component 
(SMF will take care of software components).

Make sure that you run the service and have required packages.

# fmadm config

For example, kernel sends error to FMD and FMD forwards error to module. There are two types of module: 1. Diagnosis engine : provides diagnosis based on symptoms 2. Agents : respond to given diagnosis and takes action, say offline faulty CPU. The fault manager maintains two log files: 1. error log - list of errors sent to the fault manager daemon 2. fault log - list of diagnosed and repaired problems See fault log with: # fmdump See error log with: # fmdump -e Tips: -u - limits the output to a specific UUID -T - displays events that occurred BEFORE specific time yyyy-mm-dd -t - displays events that occurred AFTER specific time yyyy-mm-dd -V - verbose output Run command below to see if Faulty Manager shows some failed resources. In this example we see that memory module DIMM 3 failed.

Fault class : fault.memory.dimm_sb
Affects     : mem:///motherboard=0/chip=1/memory-controller=0/dimm=3/rank=0
                  degraded but still in service
FRU         : "CPU 1 DIMM 3" (hc://:product-id=Sun-Fire-X4200-Server:chassis-id=0000000000:server-id=oryx/motherboard=0 
		/chip=1/memory-controller=0/dimm=3)

Description : The number of errors associated with this memory module has
              exceeded acceptable levels.  Refer to
              http://sun.com/msg/AMD-8000-2F for more information.

Response    : Pages of memory associated with this memory module are being
              removed from service as errors are reported.

Impact      : Total system memory capacity will be reduced as pages are
              retired.

Action      : Schedule a repair procedure to replace the affected memory
              module.  Use fmdump -v -u <EVENT_ID> to identify the module.



Note that there is the link with more info (like knowledge base), go there and it tells you about resolution. Okay, so say you are replacing DIMM now. Once DIMM is replaced, you need to update resource cache to indicate there is no issue any more.
# fmadm repair 2578e639-38cd-4cd8-9c16-87e96116f41e
fmadm: recorded repair to 2578e639-38cd-4cd8-9c16-87e96116f41e



Reset the Fault Manager module. Don't know which one, previously mentioned web link will tell you.
# fmadm reset eft
fmadm: eft module has been reset



Verify that there is no more faulty resources. # fmadm faulty No output, super! Means there is no h/w issue!
