P630 小型机CPU使用疑问？
一台P630 POWER4+的小型机，插入2块CPU板子，引导时认出是4个CPU，但逻辑CPU个数为何只有3个，相关命令如下：
1.查看物理CPU个数为4个
prtconf |grep Processors
Number Of Processors: 4
2.查看逻辑CPU个数为何只有3个？
pmcycles -m
CPU 0 runs at 1453 MHz
CPU 1 runs at 1453 MHz
CPU 2 runs at 1453 MHz
3.lsdev
proc0 Available 00-00 Processor
proc1 Available 00-01 Processor
proc2 Available 00-02 Processor
proc3 Available 00-03 Processor
4.Proc1 显示属性，为何会是Faulty状态？
lsattr -El proc1
frequency 0 Processor Speed False
smt_enabled false Processor SMT enabled False
smt_threads 1 Processor SMT threads False
state faulty Processor state False
type PowerPC_POWER4 Processor type False

同时在SP显示如下错误：

最新状态：
在SP里把Processor改成手动，貌似又好了
pmcycles -m
CPU 0 runs at 1453 MHz
CPU 1 runs at 1453 MHz
CPU 2 runs at 1453 MHz
CPU 3 runs at 1453 MHz
