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.
