IBM BladeCenter S SAS RAID 模块运行 400 天需重启的微码问题

 reboot controller is required的微码issue

 BladeCenter  S's two SAS RAID controller modules has received a warning: controller has been up for 400 days, reboot the controller using CLI, AMM, or SCM is required in the next 90 days.
The reason is the SAS RAID controller module firmware setting for release the cache space and prevent the controller auto reboot & hung.
We recommended to backup all data and schedule a maintenance windows to manually reboot the two SAS RAID controller modules. thanks!

我记得有好几种方式，可以在amm里对iom3或者4 restart，一般都是登陆raid卡的cli里reboot
