-----------------------------------------------------------------------------

adde.v2.common.rte                      7.1.3.0                7.1.3.45    

原因：由于adde.v2.common.rte包版本因素，导致系统没达到7100-04版本

解决办法：升级该包版本

准备文件：adde.v2.common.rte.7.1.3.45.bff

使用smitty installp命令安装

再次查看：

# instfix -i|grep ML

    All filesets for 7.1.0.0_AIX_ML were found.

    All filesets for 7100-00_AIX_ML were found.

    All filesets for 7100-01_AIX_ML were found.

    All filesets for 7100-02_AIX_ML were found.

    All filesets for 7100-03_AIX_ML were found.

    All filesets for 7100-04_AIX_ML were found.

4)        重启操作系统

四、    版本回退

如果升级版本不成功，或者和应用不兼容，需要回退版本

执行命令smitty install-> Software Maintenance and Utilities-> Reject Applied Software Updates (Use Previous Version)

包最多能选200个，分几次进行

备注：此方法在回退包过多的情况下，存在因为关联包回退不彻底现象。

这种情况，只能从mksysb或者镜像或克隆中恢复
