4.检查结果：
d27有两个submirror:d114(c0t2d0状态:OK) , d115(c2t6d0状态:Needs maintenance)。
d115的Soft Partition:d155(状态:Errored, c2t6d0s3,起始块:2890,总计块:14338107)
d31有两个submirror:d122(c0t2d0状态:OK), d123(c2t6d0状态:Needs maintenance)。
d123的Soft Partition:d161(状态:OK,c2t6d0s3,起始块:14340998,总计块: 20480121）
d55有两个submirror:d210(c0t2d0状态:OK), d211(c2t6d0状态:Needs maintenance)。
d211的Soft Partition:d173 (状态:OK,c2t6d0s3,起始块:34821120,总计块: 4194828）
由于c0t2d0的景象盘c2t6d0故障，导致其中d115、d123、d211 submirror需要维护，且有一个Soft Partition要是Errored!下面停机更换硬盘使用boot –r重新引导系统后将c2t6d0的分区重新划分和原盘c0t2d0一样。
5.删除c2t6d0原始metadb并重新创建新数据库副本
# metadb -d c2t6d0s7
# prtvtoc /dev/rdsk/c0t2d0s2|fmthard –s – /dev/rdsk/c2t6d0s2

6.将d27, d31, d55中的d115, d123, d211从镜像中分离并清除及其Soft Partition：
# metadetach -f d27 d115
# metaclear d115
# metaclear d155
# metadetach -f d31 d123
# metaclear d123
# metaclear d161
# metadetach -f d55 d211
# metaclear d211
# metaclear d173
7.重建3个软分区，重建submirror并同步：
# metainit d155 -p c2t6d0s3 -o 2890 -b 14338107
# metainit d115 1 1 d155
