Memory DIMM
disabled for DIMM n
Status.
(n = DIMM number)
Info DIMM disabled.
1. Make sure the DIMM is installed
correctly (see “Installing a memory
module” on page 250).
2. If the DIMM was disabled because
of a memory fault (memory
uncorrectable error or memory
logging limit reached), follow the
suggested actions for that error
event and restart the server.
3. Check the IBM support website for
an applicable retain tip or firmware
update that applies to this memory
event. If no memory fault is
recorded in the logs and no DIMM
connector error LED is lit, you can
re-enable the DIMM through the
Setup utility or the Advanced
Settings Utility (ASU).
