Below is SUN man page output for better understanding :
# fmdump -v -u d05a9f16-e969-4988-d340-dea1b54bd307TIME
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.

Steps for Installing Solaris patch cluster

1. Check all mirrors for "needs maintenance", and if there are any, "metasync" those.

2. "metadetach" the mirror

3. "init 0"

4. "OK> boot -s"

5. If necessary, "zfs mount -a" to get everything mounted in single-user

6. "install_cluster"

7. "init 0"

8. "boot -r"
9. "metattach" the mirror that was broken
