超级奇怪的问题，启动的时候，第一块硬盘找不到

zwzw110

有一个V440机器，有4个147G的硬盘，OS是solaris8
出现问题如下，从硬盘启动的时候，无法mount第一块硬盘，并且使用format，无法发现第一块硬盘，使用prtvtoc检测，c1t0d0s0和c1t0d0s1的flags为10（read－only）；但是如果通过cdrom启动，就是正常的，format和prtvtoc都能得到正确的结果；如果在ok下，用probe-scsi-all，也能检测到4个硬盘

从硬盘启动，出现如下错误：

请教各位高手，到底是什么原因导致从硬盘启动无法发现第一个硬盘？

race

fsck -F ufs -o b=993312 /dev/dsk/cit0d0s0
这个超级块不是你的备用超级块，只是硬盘上表明坏块的地方。
newfs -N /dev/dsk/c1t0d0s0 查看可用的超级块，然后b=显示出来的超级块替换

zwzw110

fsck -F ufs -o b=993312 /dev/dsk/cit0d0s0中的 993312就是通过newfs -N /dev/dsk/c1t0d0s0查找出来的，使用了好几个其他的超级快，都出现同样的错误。 关键是执行之后，报Alternate super block location: 993312.
** /dev/rdsk/c1t0d0s0 (NO WRITE)
就是找到备用超级快，也写不到硬盘里去，因为硬盘1没有认出来。
就是想知道用什么方法可以在硬盘启动的时候认出第一块硬盘
