UUID SUNW-MSG-IDAug 17 07:18:43.9562 d05a9f16-e969-4988-d340-dea1b54bd307 SUN4U-8000-2S100% fault.memory.dimmFRU: mem:///component=J0202rsrc: mem:///component=J0202
Once the DIMM(s) have been replaced, the command fmadm faulty should be run to see the status of the memory involved.
Example:
# fmadm faulty
STATE RESOURCE / UUID——– ———————————————————————-degraded mem:///component=J02029f32d247-869f-c9f2-949b-d9ec88b09640——– ———————————————————————-
Then fmadm repair should be run to remove the memory from the faulty list.
# fmadm repair mem:///component=J0202
fmadm: recorded repair to mem:///component=J0202
Verifying the results: After issuing the above commands, you can check the status of memory modules by issuing fmadm faulty command. this time it will not list any results.
