3.解决方法（修改vfstab和system文件）
3.1.进入ok模式
在维护模式输入init0进入ok模式
#init0
#svc.startd:
Thesystemiscomingdown.Pleasewait.
svc.startd:
81systemservicesarenowbeingstopped.

3.2.从光盘引导进入单用户模式
把盘放入光驱，bootcdrom–s从光盘引导进入单用户模式
okbootcdrom-s

#mount/dev/dsk/c0t1d0s0/a//把c0t1d0s0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
3.4.修改vsftab和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。
#TERM=vt100;
exportTERM;
//修改当前环境变量，用户vi编辑
#cd/a/etc//进入/a/etc/目录
#cpvfstabvfstab.bak//备份vfstab文件
#vivfstab//编辑vfstab文件
//注释掉镜像的行，添加关于磁盘分区的信息

3.5.Umount目录/a
编辑好/a/etc/vfstab和/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
3.6.重启系统并查看系统状态
重启系统，并查看系统状态
