Memory Failures
The B2000 system implements Memory Page Deallocation. This feature allows the
workstation to provide information to the operating system about memory failures.
HP-UX 10.20 uses information to map out failing memory areas and continue normal
operation. You can use the command
memrpt
with the
detail
switch to obtain information
about the Memory Page Deallocation Table (PDT) as well as single-bit errors logged by the
system, as follows:
# /usr/sbin/sysdiag
Enter
DUI > logtool
Enter
LOGTOOL> memrpt detail
Enter
The PDT can also be checked using the
pdt
command in the Service menu of the Boot
Console Handler (refer to Chapter 6).
For allowable memory configurations, see the “Memory” section on page 38.
