硬盘mount不上该如何处理！！！急

anson23

我的硬盘因为掉电，现在显示文件系统损坏。
可是我从光盘启动，无法mount 上硬盘，
＃mount /dev/dsk/c0t3d0s0 /tmp
  no such device or file!
我再用
＃format
search devices ......
  no hard disk !
可是我用dmesg命令可以看见硬盘！！
到底该如何是好！！！！急！！

/dev目录对吗？

我现在mount上了！
可是重新启动仍然报错：
/sbin/swapadd.expor:not found
/usr/sbin/swap not found
/usr/sbin/fsck nor found
........
我用fsck超级模块恢复了，可是还是出现这样问题？
如何是好？？？？

我现在的错误信息：（在boot开始）

我已经做过FSCK的超级块修复，可是问题依然！！

我从网上找到相应的回答。试着做了一下命令是没问题，可是好像没什么改变！方法如下：请高手指教错误在哪里？？！！
Two options are available.

A. Move the disk to a SCSI address that the user knows has been
defined in
the /devices directory. An example of this would be if the disk was
cloned
while installed at target 2 from a disk at target 0, both of those
targets
would be acceptable for this disk as they are fully 'defined'.

B. Create new /dev, /devices and path_to_inst entries based on the new
disk
location using the configuration generated by booting from cdrom.

   NOTE: This will only work if the architecture of the system is the
         same as that installed on the disk, for instance you can not
         move a disk from an Ultra2 to an Ultra450 as the two systems
         use different bus architectures. By the same token you could
         not move the Ultra2 disk to a SPARCstation20 as the hardware
         architectures are not compatible.

The steps to take when using option B are:

   ok boot cdrom -s
   ...
   # mount /dev/dsk/c0t3d0s0 /a        <--- t3 is being used as an example
only
   # cd /tmp/dev
   # tar cvfp - . | ( cd /a/dev; tar xvfp - )
   # cd /tmp/devices
   # tar cvfp - . | ( cd /a/devices; tar xvfp - )
   # cd /tmp/root/etc
   # cp path_to_inst /a/etc/path_to_inst

   NOTE: The vfstab file may need to be edited at this time to make
any
         changes to the target address

   # cd /tmp/root; umount /a; halt
   ...
   ok boot -rv

OKboot cdrom -sw
#fsck -y
#mount /dev/dsk/c0t0d0s0 /mnt
#more /etc/vfstab               ****check each mount point
# mount                              ****mount each mount point
