by Tom Chalfant
May, 2004

Processor off-lining is a feature whereby a processor is removed from use by Solaris in response to one or more L2 cache errors. Page retirement is a feature whereby a page of memory is removed from use by Solaris in response to repeated ECC errors within a memory page on a DIMM. This paper provides detailed discussion regarding the algorithm, implementation, kernel tunables, and the messages you are likely to see on a system running the appropriate kernel updates.
