紧急问题！！！！！

unix-xyz

紧急问题，操作系统启动不成功，报以下错误，我现在知道错误所在了，可是如何修复呀？主要问题是做完系统镜像后，vfstab文件也都改成md的了，后来在调试文件系统时，又将以前备份的vfstab文件改成现在可用的vfstab文件，将改成md文件系统vfstab改名了，现在就启动不了，只能进入单用户模式，且vfstab等文件不能编辑，有什么办法吗？
[root@test]# ls -al vf*

[root@test]# mv vfstab vfstab1

mv: cannot rename vfstab to vfstab1: Read-only file system

Try mount -o remote,rw /
If it doesn't work, try
df -k to find out which device is mounted on / and issue: mount -o remote,rw the_device_name

unix-xyz

我刚才按照这个方法做了一下：
镜像盘的boot引导：
①启动信息
#installboot /usr/platform/`uname –i`/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0
（本系统是solaris10，做这步时提示如下，不知是否完毕：
[root@test]# installboot /usr/platform/ 'uname -i' /lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0
Usage: installboot bootblk raw-device
[root@test]# installboot /usr/platform/'uname -i' /lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0
Usage: installboot bootblk raw-device
[root@test]# installboot /usr/platform/'uname -i'/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0
/usr/platform/uname -i/lib/fs/ufs/bootblk: File not found ）

②修改EEPROM
推荐进入OK模式修改
#ls –l /dev/dsk/c0t0d0s0 **获得启动参数
lrwxrwxrwx 1 root root 41 Jun 14 11:08 /dev/dsk/c0t0d0s0 -> ../../devices/pci@1f,4000/scsi@3/sd@0,0:a
#init 0
ok devalias （察看启动设备）
ok nvalias rootdisk /pci@1f,4000/scsi@3/disk@0,0
ok nvalias mirrdisk /pci@1f,4000/scsi@3/disk@1,0
ok setenv boot-device rootdisk mirrdisk disk:a
③测试
ok boot rootdisk **系统正常启动，找到启动文件
ok boot mirrdisk **系统正常启动，找到启动文件
现在系统的/目前成了
Filesystem            kbytes    used   avail capacity  Mounted on
/pseudo/md@0:0,0,blk 10332220 1018434 9210464    10%    /

谢谢你的解答。
vfstab文件肯定是在/目录下，如果mount -o /的话，系统会不会启不来呀，也就是说连单用户模式都进不了，我是第一次做，谢谢你的继续答复。

现在的问题就是要如何将vfstab文件中的/dev/dsk/c0t0d0s* 改为/dev/md/dsk/d*

当然,前提是有网络引导. 试试看boot cdrom -s后修复呢?

试着boot cdrom -s了，可是提示需要输入filename，输入什么呢，试着输入vfstab，提示not found this file，输入其它也是，下一步该如何呢

mount -o remote,rw /
无法做这步，总是提示/ busy

没记错的话,应该输入unix
