Changing the memory configuration
Display data for each memory unit and bank. You can change the state of each bank.
Each memory bank contains two DIMMs (dual inline memory
module). If the firmware detects a failure, or predictive failure,
of a DIMM, it deconfigures the DIMM with the failure, as well as the
other DIMM, in the memory bank. If memory DIMMs are being monitored
for errors, each memory bank will be in one of the following states:
- Configured by system (cs)
- Manually configured (mc)
- Deconfigured by system (ds)
- Manually deconfigured (md)
Each physical DIMM can contain a maximum of eight logical DIMMs. Each of the logical DIMMs can be configured or deconfigured individually.
With the ASMI, you can change
the state of the memory bank from cs to md, from mc to md,
and from md to mc for one or more DIMMs. If one DIMM
is deconfigured, the other DIMM in the memory bank automatically becomes
deconfigured.
Note: You can change the state of the memory bank only
if the deconfiguration policy is enabled for the memory domain. If
this policy is not enabled and you try to change the state, an error
message is displayed.
The error type is the cause of memory deconfiguration and applies to the bank in the ds state. The error type is displayed only when the bank is in the ds state.
To
perform this operation, you must have one of the following authority
levels:
- Administrator
- Authorized service provider
To view or change the memory configuration, do the following steps:
