Solaris[TM]: How to Display Retired Memory Pages (Doc ID 1004934.1)

Last updated on JULY 06, 2023

Applies to:

Solaris Operating System - Version 8 and later
All Platforms

Goal

In the event of an error correction code(ECC) memory error, which advises that the memory page has been scheduled for retirement, it can be useful to know if the page has actually been retired.
For example, the following message indicates that the error count threshold has been exceeded, and the page is scheduled for retirement:

May 31 12:34:55 host-a unix: [ID 618185 kern.notice] WARNING: [AFT0] 3 soft errors in less than 24:00 (hh:mm) detected from Memory Module SB3/P3/B1/D0 J16301
May 31 12:34:55 host-a unix: [ID 618185 kern.notice] NOTICE: Scheduling removal of page 0x00000062.44bfa000
