求助！root忘记密码了，网上的方法用过了还是不行。很着急
本帖最后由 feiniao222 于 2011-10-30 13:20 编辑小弟的v240机器信息如下：
1.format 信息如下，从信息上看不出是否已经作了镜像。似乎根盘时c1t0d0s0，不知道对不对。

各位，有什么办法帮我解决以下，很是着急啊。郁闷！ 请各位帮帮忙，小弟实在搞不了了，疯掉！ 希望大家给我看看，怎样才可以把root密码清掉。谢谢！ 在OK下打printenv 查看启动的硬盘顺序
在OK下setenv 可以指定启动硬盘,指定你改好密码的那一块
这样试试. bootcdrom-s
mount/dev/dsk/c1t0d0s0/mnt
cd/mnt/etc
cat vfstab
看分区表中目录挂载情况，然后再请密码。如果做过镜像，两块盘都要清除shadow中的密码。:em27: 如果做过镜像，需要修改另外一块硬盘的shadow文件，或者拆除镜像然后从c0t0d0启动然后进去再做镜像。 试着拔出一块盘，再修改相关的文件，做了mirror直接手工改2个文件是不行的，虽然文件的内容改后是一样的
或者找张带VXVM环境的光盘启动，import rootdg，修改相关文件试试 回复 7# calcm
谢谢大家的帮助，问题解决了！
