Memory Failures - HP Visualize J280 Owner's Manual

Memory
Failures
J Class systems use Memory Page Deallocation, a feature that allows
the system to provide information to the operating system about

memory failures.

HP-UX 10.20 uses Memory Page Deallocation information to map
out the failing memory areas, and continue normal operation. You can
use the command memrpt with the detail switch to obtain informa-
tion about the Memory Page Deallocation Table (PDT) as well as
single bit errors logged by the system.
# /usr/sbin/sysdiag
DUI >logtool
LOGTOOL> memrpt detail
NOTICE: You must be logged in as superuser to use the
memrpt command.
To exit the sysdiag and logtool utilities, use the exit command.
The pdt can also be checked using the pdt command in the Service
menu of the boot console handler. If a failing DIMM is replaced, use
the Service menu pdt clear command to clear out the PDT.
