SPARC T5 Series and SPARC M5-32/M6-32 Servers System Firmware Version 9.4.2.c and 9.4.2.d May Erroneously Disable CPUs (Doc ID 2027245.1)
Description
For SPARC T5 Series and SPARC M5-32/M6-32 Servers system firmware, the memory retirement function supports the ability to take portions of memory DIMMs offline proactively in response to certain error conditions. With system firmware Version 9.4.2.c and 9.4.2.d, when a retirement occurs, and during subsequent boots, the firmware will also disable the perfectly functional CPUs with which that memory is associated. This can result in a loss of performance or the inability to bind resources to guest domains.
