Determine Which DIMM Is Faulty (Oracle ILOM)
■
DDR channel (CH) number (where z is
0
or
1
)
This information is useful when servicing DIMMs and when assessing error messages. For
example, the following output identifies faulty DIMMs on two different SPARC M7 CMIOUs.
2013-09-06/17:16:20 ereport.hc.dev_fault@/SYS/CMIOU1/CM/CMP/BOB11/CH1/DIMM

Determine Which DIMM Is Faulty (Oracle ILOM)
At the Oracle ILOM prompt, type
show faulty
.
The following output might be slightly different, depending on the server in use.

The first line of the preceding output shows the CMIOU number, buffer chip number, and DDR
channel number. See “DIMM Names” on page 108 for information about the slot numbers
on the CMIOU.
Note - If two DIMMs are reported as faulty, replace both of the DIMMs.
