IBM小型机检查命令

三：查看报错信息主要查看硬件的永久性报错#errpt-dH|pg软件的永久性报错#errpt-dS|pg系统报警灯四、机器的序列号#uname-MuIBM,9131-52AIBM,030666C5G五、操作系统版本：#oslevel-r# oslevel-r5300-05注：有时候不能使用是因为系统版本低的原因。六、其他检测1、执行sysdumpdevl检查dump是否设置为alwaysallowsysdump；#

、检查是否有raid保护#smittyssaraid-ListAllDefinedSSARAIDArrays(2) 、检查是否有HotSpare#smittyssaraid-ListComponentsinaHotSparePoolListAllDefinedSSARAIDArrays查看71330对于7133，执行Smittyssaraidraid状态，正常应该为good状态。Change/ShowUseofanSSA对于7133，执行SmittyssaraidPhysicalDisk查看7133硬盘状态，正常应该为member或者spare状态对于FastT，分别登录上两个controller，查看是否有错误日志。
