ØRS6000有2种结构,一种是经典的采用微通道结构的MCA总线,一种是PCI总线,现在几乎全部都是PCI总线,比如试验机43p-150
ØPowerPC是1991年IBM,APPLE,MOTOROLA公司共同开发
ØPowerPC604E是1995年的产品,支持WindowsNT3.51和4.0

Ø临时性修正软件PTF,也就是补丁,分为2种维护包ML和推荐维护包RM
Ø确定是否可以从PowerPC上引导CDROM,如果返回部件号是04N2964则需要升级CDROM的微码。

Ø操作系统的运行级别有11个,编码是0-9,s,S,m,M。由/etc/inittab控制,其中四个字母表示单用户模式,也就是维护模式,0,1没有定义是为以后保留的,2是生产模式多用户状态,切换运行级别inits中止其中的进程使用ctrl+D
Ø查看运行级别#vi/etc/inittab

Ø所有PCI机器都有一个SMS系统管理维护工具,在GUI中F1即可
Ø系统启动时会记录一些启动日志,以帮助系统管理员日后检查系统启动是否正常,系统管理员有时需要检查或研究系统的启动过程。发现系统是否存在问题,系统启动时会调用rc.boot命令文件
#alog-L
boot
bosinst
nim
console
cfg
lvmcfg
lvmt
dumpsymp
#alog-o-tboot
查看引导信息
Ø安全的关闭系统shutdown+30表示30分钟后关闭系统,-i交互方式,-F
ØHalt必须由root执行,必须root用户以外的所有其他用户全部退出,实际上halt调用fasthalt命令停止。此命令会丢失数据破坏文件系统
Ø重启可以使用shutdown-r或者快速方式-Fr
Ø查看关闭系统的日子信息,首先shutdown-l,cat/etc/shutdown.log
ØSMIT是SystemManagementInterfaceTool的简称,降低复杂度,有日志可查

ØSmit中*表示要填写一个合法的值,#表示填写数字,/表示填写路径,x表示填写16进制的值,?表示填写的内容不会显示出来,+表示可以从弹出式列表中选择
ØSmit运行中会生成2个文件,smit.script和smit.log,其中,script记录带参数的文件,实际上这是一个shell脚本,root用户可以检查其他用户使用smit的情况。
