CME Option - H06.16/J06.05 and later RVUs

The CME option displays relevant information related to correctable memory errors

(CMEs) that have occurred since the processor was last loaded.

The occurrence of CMEs is considered normal with the high-density memory

technology used in Integrity NonStop servers and in HP Neoview platforms. CMEs are

handled automatically. No EMS event is logged in response to a CME.

When appropriate, a CME can result in removal of the enclosing memory page from

further use. A limit is placed on the number of such page removals, based on a small

percentage of total memory size.

When you enter the command PEEK /CPU 0/ CME , an output similar to this example

is generated:

PEEK - T9050J02 - (01MAY05) - (31MAY05) SYSTEM \HALF3

SYSTEM \HALF3

8 JUN 2005 , 12:42___ELAPSD 16:17:03___CPU 0(NSE-P)___Num IPUs=2

AVAILABLE FUTURE CME PAGE REMOVALS: <value>

where,

<value> starts (upon reload of the processor) at the maximum number of allowed

page removals for the processor and decreases as pages are removed from use.

A <value> of zero is the only condition for which a CME-related service action might

be considered appropriate (although not required). It is not recommended to take

special step

s to monitor for this condition; however, if you observe that <value > has

reached zero, contact the Global Mission Critical Solution Center (GMCSC) to

determine whether a service action is appropriate.

The <value> is re-initialized to the maximum number of allowed page removals

for

the processor only upon reload of the processor. This behavior is independent of

whether or not a CME-related service action has been performed.

CME Option - For releases before H06.16/J06.05 RVU

The CME option displays the number of correctable memory errors (CMEs) that have

occurred since the processor was last loaded. The CME display reflects only initialized

pages and can indicate chip or address-line failures. For definitions of the terms, see

the Glossary.

Note. The “Num IPUs” option shown in the above example is visible in the ouput generated

by a system running on J-series RVU only and not on a system running on H-series RVU.

The “NSE-P” value shown in

the above example is specific to the particular Processor Type

and CPU Model that PEEK is running on. For more information about the processor types

used, see the Guardian Procedure Calls Reference Manual.
