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 10.0 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 information
about the Memory Page Deallocation Table (PDT) as well as single
bit errors logged by the system.
# /usr/sbin/sysdiag
Enter
DUI >logtool
Enter
LOGTOOL> memrpt detail
Enter
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 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:
