Description
unexpected duplicate address-type or
context-type reply. This could indicate a
hardware, blade server firmware, or
SAS expansion card firmware problem.
reply-type is Address for an
address-type reply and Context for a
context-type reply.
Description
The DIMM is not a DDR2 DIMM.
The DIMM is not a registered DIMM.
The maximum I/O-frequency of the
DIMM is slower than memory
controller's frequency.
The DIMM does not provide a CAS
Latency setting for an I/O-frequency of
333 MHz or the configuration data is
inconsistent.
The DIMM does not support a Burst
Length of 4.
The DIMM has a bank count different
from 4 and 8.
The DIMM's the data width is different
from 36 and 72.
Action
1. Reboot the blade.
2. Power down then remove and
reinstall the blade server in the
BladeCenter unit.
3. Remove and reinstall the SAS
Expansion Card.
4. Ensure the SAS Expansion Card
firmware and blade firmware
version are at the correct level.
5. If the error started after a SAS
Expansion Card firmware upgrade
or a blade server firmware
upgrade, consider a rollback to the
previous firmware versions. Check
with the documentation at
http://www.ibm.com/systems/
bladecenter/support/ to verify
whether rollback is possible.
6. Plug the SAS expansion card into
another blade server. If the problem
persists, the SAS Expansion Card
may need replacement.
7. Plug a different SAS expansion
card into the blade server. If the
problem persists, the blade server
system board may need
replacement.
Action
Replace the DIMM with a DIMM of type
DDR2.
Replace the DIMM with a DIMM of type
"registered".
Replace the DIMM with a DIMM
allowing an I/O-frequency of at least
333MHz.
Replace the DIMM with a DIMM with
correct configuration data.
Replace the DIMM with a DIMM
supporting a Burst Length of 4.
Replace the DIMM with a DIMM with a
bank count of 4 or 8.
Replace the DIMM with a DIMM with a
data width of 36 or 72.
