1、操作之前先备份/etc/vfstab和/etc/system文件。
2、结合metastat -p和df -k察看对应的c#t#d#s#
不过我建议你修改前，先在ok状态，试试boot disk0还有boot disk1看看能不能正常启动到系统，然后再选择如何操作

首先感谢您的回复！我今天在ok模式下，先检查了机器一些信息如下:

然后我boot disk0失败了，跟重启时是一样的报错unexpected free inode 304295, run fsck(1M) -o f
然后我boot disk1就起来了，telnet也正常了
这是不是说镜像： d22是好的，d21有问题了？现在我该怎么修复？另外大侠您有QQ吗？真的很想跟你QQ沟通一下。。。。。万分感谢！

另外我还有一个概念性的问题不清楚啊，根卷镜像，目的是什么？就是以后启动从镜像启动而非原来的根卷路径启动吗，以此来备份和保护原有的根卷文件系统？
我/dev/dsk下面的输出如下：

那是不是说我有3块物理上分开的硬盘？
IDE盘c0t0d0
SCSI盘c1t0d0
SCSI盘c1t1d0
在没做镜像之前，启动系统是从c0t0d0s0开始的，做了主镜像之后是从c1t0d0s0开始的，我们还有一个次镜像是从c1t1d0s0开始的。那么说我做的boot disk1就是从c1t1d0s0开始启动的，这样理解对吗？
那么我现在需要修复的应该是fsck /dev/dsk/c1t0d0s0而非fsck /dev/dsk/c0t0d0s0？是这样的吗？
另外我在devalias中看到
ide /pci@1e,600000/ide@d
disk3 /pci@1c,600000/scsi@2/disk@3,0
disk2 /pci@1c,600000/scsi@2/disk@2,0
disk1 /pci@1c,600000/scsi@2/disk@1,0
disk0 /pci@1c,600000/scsi@2/disk@0,0
disk /pci@1c,600000/scsi@2/disk@0,0
按照我的理解，我应该只有disk0，disk1，ide啊，怎么冒出来的disk2和disk3？不明白了。。。
新人上路，很多问题很幼稚，多多包涵啊。。。。。感谢授业解惑！！！

昨天metareplace -e d20 c1t0d0s0之后，等待N长时间，Submirror d21状态变为OK了。然后metasync d20了一下,重启，root disk0居然好了。这是不是代表没问题了呢？
boot-s
fsck-y
reboot -- -r 回复 14# xzq12900
看一下metastat和metadb的状态，如果Submirror 状态都是OK，metadb状态也正常，那么应该是问题不大了。
另外可以看看messages日志和iostat -En对应的硬盘各种errors的数值，如果数值过大或者不停增长，就需要考虑更换硬盘了。
看一下你的eeprom输出，应该是系统镜像的启动盘设置的不全，只设置了disk0盘启动
