3.4.5.2 Determining When to Replace Detected Devices
Note –
This section assumes faults are detected by POST in maximum mode.
If a detected device is part of a hardware upgrade or repair, or if POST detects
multiple DIMMs (
CODE EXAMPLE 3-2
), replace the detected devices.
Note – The previous example shows two DIMMs on the same channel/rank, which
could be an uncorrectable error.
If the detected device is not a part of a hardware upgrade or repair, use the following
list to examine and repair the fault:
1. If a detected device is not a DIMM, or if more than a single DIMM is detected,
replace the detected devices.
2. If a detected device is a single DIMM and the same DIMM is also detected by
PSH, replace the DIMM (
CODE EXAMPLE 3-3
).
Note –
The detected DIMM in the previous example must also be replaced because
it exceeds the PSH page retire threshold.
