1.用format查看系统硬盘状态:
[code:1:1bc760b98d]# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
       0. c0t0d0 
          /sbus@3,0/SUNW,socal@d,10000/sf@0,0/ssd@w2100000c507be33a,0

2.使用metadb查看db库状态:
[code:1:1bc760b98d]# metadb

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
[code:1:1bc760b98d]# metadb -d c2t6d0s7
# prtvtoc /dev/rdsk/c0t2d0s2|fmthard –s – /dev/rdsk/c2t6d0s2
# metadb -a -f -c 1 c2t6d0s7
# metadb   查看db库状态
        flags           first blk       block count
     a m  p  luo        16              1034            /dev/dsk/c0t0d0s7
     a    p  luo        16              1034            /dev/dsk/c0t1d0s7

     a    p  luo        16              1034            /dev/dsk/c2t4d0s7
     a    p  luo        16              1034            /dev/dsk/c2t5d0s7

     a    p  luo        16              1034            /dev/dsk/c2t7d0s7[/code:1:1bc760b98d]

6.将d27, d31, d55中的d115, d123, d211从镜像中分离并清除及其Soft Partition:
[code:1:1bc760b98d]# metadetach -f d27 d115
# metaclear d115
# metaclear d155

# metadetach -f d31 d123
# metaclear d123
# metaclear d161

# metadetach -f d55 d211
# metaclear d211
# metaclear d173[/code:1:1bc760b98d]

7.重建3个软分区,重建submirror并同步:
[code:1:1bc760b98d]# metainit d155 -p c2t6d0s3 -o 2890  -b 14338107 
# metainit d115 1 1 d155
# metattach d27 d115

# metainit d161 -p c2t6d0s3 -o 14340998  -b 20480121 
# metainit d123 1 1 d161
# metattach d31 d123

# metainit d173 -p c2t6d0s3 -o 34821120  -b 4194828 
# metainit d211 1 1 d173
# metattach d55 d211[/code:1:1bc760b98d]

8.使用metastat查看同步情况:
[code:1:1bc760b98d]# metastat d27
# metastat d31
# metastat d55[/code:1:1bc760b98d]

9. 同步完成检查metastat状态,全部OK,故障解决!

[color=red:1bc760b98d][b:1bc760b98d]呵呵,所有数据资料有pengtao_hlp现场提供(辛苦了,功劳是属于你的!),我做的完善和整理!  [/b:1bc760b98d][/color:1bc760b98d]:oops:

10.补充一下soft partition概念
来自:UNIX中文宝库    

背景 
由于硬盘变得越来越大,而且对于solaris系统来说磁盘阵列是一个比较大的逻辑设备,一些用户提出了需求:要求划分超过8个的细分硬盘和逻辑卷,并且创造易于管理的文件系统和分区大小。这样,soft partition技术就被引进到solaris系统中来了。 

术语介绍: 
Metadevices: 他们是类似物理硬盘分区的逻辑设备。他们习惯常常被用于描述一个单独的硬盘分区或是一组硬盘驱动器或硬盘分区。通常像下面一样命名metadevices设备: 
/dev/md/(r)dsk/d[0-255] 

Submirror: 一组由metadevice构成的逻辑设备。一个submirror不是striped就是concatenated的metadevices。 

Metamirror: 一组submirrors的逻辑联合。系统创建的所有的metamirrors至少由两个submirrors组成。每个组中的submirror包含数据的全部拷贝并且位于一个不同的硬盘上。因此如果一个disk出问题,通过恢复其他硬盘上的submirror数据完整性不会受损。这种通过双submirror的数据的复制是DiskSuite实现镜像的习惯。一个metamirror可以包括3个submirror。 

Soft Partition:Soft partitions被用来将一个disk slice或者逻辑卷划分成多个partition,具体数量根据需求来定。Soft partitions可以直接被放置在disk slice上,或者一个mirrror的顶端。Soft partitions被应用于除了根分区(root partition)和交换分区(swap partition)之外的所有分区上。

至于具体怎么创建,查看,扩大,删除和恢复,我会在以后详细介绍给大家!谢谢支持,谢谢支持CU!

看了半天,不明白为什么不用原有的7个slice做,命名感觉好混乱。
