In the Solaris 9 8/03 operating environment, on UltraSPARC II based systems, the CP Event message that accompanies some Uncorrectable Memory Error messages is not always produced. These include the following systems:
Sun EnterpriseTM 10000
Sun Enterprise 6500
Sun Enterprise 6000
Sun Enterprise 5500
Sun Enterprise 5000
Sun Enterprise 4500
Sun Enterprise 4000
Sun Enterprise 3500
Sun Enterprise 3000
The result is that some information needed to identify a failing CPU might not always be present.
