Descriptions for the states of the power supply LEDs follow:
If both the ac power and dc power (green) LEDs are on solid (not flashing) and the error and identify function (amber) LED is off, the power supply is operating correctly. If the ac power LED is on, the dc power LED is flashing, and the error and identify function (amber) LED is off, then the system is turned off, but the power supply is still connected to the power source. If the error and identify function (amber) LED is flashing, the power supply is not operating correctly or the identify function has been selected.4.查找机器的s/n号,打IBM 800报修
5.第二天配件到后,根据IBM硬件信息中的提示更换电源。为了保险起见,我先把主机上的应用切换到备机上--->shutdown主机-->下电-->换电源-->上电等待3分钟自检--->启操作系统--->起HA--->把应用切回主机---->测试应用正常---->换电源完毕
后记:因为是双电源,所以换电源本来是一个很简单的操作,即拔即插就行,完全可以下线操作。但是为了顺便测试一下HA,所以做以上操作。尽管整个过程耗时不多,但在切换过程中备机还是不能takeover RG,原因是Oracle的某些配置文件在主机上修改还没有在备机上同步修改,所以告戒所有系统管理员,HA是好,但是怎样让它好是你需要把握的。
