Operating System Overview; Memory Failures - HP Visualize J5000 - Workstation Service Handbook

Operating System Overview

This workstation uses the HP-UX operating system, versions 9.05 PCO1 or 10.0 and
later. Instant Ignition systems (systems with preloaded software) have X-windows
and the Hewlett-Packard HP VUE 3.0 graphical user interface installed and
configured. See the user's guide for more information.
To verify which version of the operating system you are running, use the following
command in a terminal window:
# grep fv /system/UX-CORE/index
If you're running HP-UX 9.05 PCO1, the result from this command will be:
fv: A.B.9.05.1M
For problems or questions with Instant Ignition, refer to Using Your HP Workstation
for more information.

Memory Failures

The J Class system (with HP-UX 10.0 and later) uses Memory Page Deallocation, a
feature that allows the system to provide information to the operating system about
memory failures.
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.
# /usr/sbin/sysdiag
DUI >logtool
Enter
LOGTOOL> memrpt detail
The pdt can also be checked using the pdt command in the Service menu of the boot
console handler (Refer to Chapter 9). If a failing SIMM is replaced, use the Service
menu pdt clear command to clear out the PDT.
HP-UX 9.05 halts when it detects the presence of bad memory at boot up and
displays the following message:
ISL booting hpux
