Memory Failures
The J6000 workstations require special Memory Page Deallocation to be implemented.
This feature allows the workstation to provide information to the operating system about
memory failures.
HP-UX uses this information to map out failing memory areas and continue normal
operation. You can check the Memory Page Deallocation Table (PDT) using the pdt
command in the Service menu of the Boot Console Handler (refer to Chapter 4). If a failing
DIMM is replaced, use the command pdt clear in the Service Menu to clear out the PDT.
