3. 解决方法1(修改system文件)
3.1. 进入ok模式
在维护模式输入init 0进入ok模式
# init 0
# svc.startd: The system is coming down. Please wait. svc.startd: 81 system services are now being stopped. svc.startd: The system is down. syncing file systems... done Program terminated ok ok

3.3. 修改/etc/system文件
在format中查看硬盘，找到系统根目录所在分区，并把该分区挂载给/a。

partition> # #
# mount /dev/dsk/c1t0d0s0 /a //把c1t0d0s0分区mount到/a目录
有时会提示需要fsck先检测磁盘的文件系统，如果文件系统损坏则无法mount #
# TERM=vt100;export TERM; //修改当前环境变量，用户vi编辑 # cd /a/etc //进入/a/etc/目录，不要直接vi /etc/system #cp system system.bak //备份system文件
# vi system //编辑/a/etc/system文件
* Begin MDD root info (do not edit) rootdev:/pseudo/md@0:0,100,blk * End MDD root info (do not edit)
set md:mirrored_root_flag=1 //最后加入这一行，用户在metadb 仅一半有效时
候仍能启动系统
3.4. Umount目录/a
编辑好/a/etc/system文件后，取消mount的/a目录,不mount可能会出现挂载问题；
# cd / //回到根目录， # umount /a //umount 目录/a
3.5. 重启系统并查看系统状态
重启系统，并查看系统状态。
