对vfstab 文件修改错误后怎么样修改
/etc/vfstab原先bash-3.00# vi /etc/vfstab#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/dsk/c0t0d0s1 - - swap - no -
/dev/md/dsk/d0/dev/md/rdsk/d0 / ufs 1 no -
/dev/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /usr ufs 1 no
-
/dev/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4 /var ufs 1 no
-
/dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /data ufs 2 yes
-
/dev/dsk/c0t0d0s3 /dev/rdsk/c0t0d0s3 /opt ufs 2 yes
-
/devices - /devices devfs - no -
sharefs - /etc/dfs/sharetab sharefs - no -
ctfs - /system/contract ctfs - no -
objfs - /system/objectobjfs - no -
swap - /tmp tmpfs - yes -
~
然后做了镜像修改了/etc/vfstab
/dev/md/dsk/c0t0d0s1 - - swap - no -
/dev/md/dsk/d0/dev/md/rdsk/d0 / ufs 1 no -
/dev/md/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /usr ufs 1 no
-
/dev/md/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4 /var ufs 1 no
-
/dev/md/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /data ufs 2 yes
-
/dev/md/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /usr ufs 1 no
-
重启后出现了如下的提示

现在是目录也找不到 也挂不上去
不想做操作系统
各位能不能帮出个主意??? /dev/md/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /usr ufs 1 no
-
要改成：
/dev/md/dsk/d5 /dev/md/rdsk/d5 /usr ufs 1 no

这个样子 对,是这样的,但是目前,/opt /var /等目录都挂不上,命令也用不了,我修改之前把/etc/vfstab这个文件备份,怎么样给他恢复呢? Boot from CDROM, or from Jumpstart.... 用光盘引导到单用户模式下修改好了 先光盘进入，会挂载在/a下面，修改正确后就能正常启动了，以后要注意一下，修改任何文件之前，一定要先备份，呵呵，这也是一位老鸟教我的，你的问题，我前不久就碰到过！ 光盘引导进到单用户
