RAID1和RAID5的安装及恢复

本文档以SUN Fire V 880 Server 6*73GB Dsik为例讲解在Solarsi8下使用命令行的方式安装及维护RAI D 1和RAID 5。本文档内容都经本人实践验证过但对于不同机型仅供参考谢谢支持

Disk分布情况

0:c1t0d0

1:c1t1d0

2:c1t2d0

3:c1t3d0

4:c1t4d0

5:c1t5d0

注 0,1做镜像 2 3 4 5做RAI D 5

系统安装完成后使用Solarsi8 software 2 of 2安装DiskSuite_4.2.1软件安装路径/cdrom/cd rom0/Solaris_8/EA/insta l ler&选择默认安装就可以。

用root用户登陆,运行以下命令

#prtvtoc/dev/rdsk/c 1t0d0s2|fmthard–s–/dev/rdsk/c 1t1 d0s2fmthard:New volume table of contents now in place

上面命令将第二块硬盘(c1t1d0)的文件分区表调整为和引导盘一致。

#u m o u nt/m eta D B

#rm–r/metaDB

#v i/etc/vfsta b

将下面这行注释掉或删除,如下

#/dev/dsk/c1t0d0s7/dev/rdsk/c1t0d0s7/metaDB ufs 1 yes–

一、 RAID 1

对各个分区逐一作镜像

①先生成replica s,这是D iskSu it e内部用的。

#metadb–a–f–c 3 c1t0d0s7 c1t1d0s7

#metad b

②Creating a mirro r from swap

#metainit–f d11 1 1 c1t0d0s1

#metainit d21 1 1 c1t1t0s1

#metainit d1–m d11

#v i/etc/vfsta b

/dev/dsk/c 1t0d0s1 - -swap–no–should be changed to:

/dev/md/dsk/d 1 - -swap–no-

#reboot

#metattach d1 d21

③Creating a mirro r from/usr

#metainit–f d13 1 1 c1t0d0s3

#metainit d23 1 1 c1t1t0s3

#metainit d3–m d13

#v i/etc/vfsta b

/dev/md/dsk/d3/dev/md/rdsk/d3/usr ufs 1 yes–#reboot

#metattach d3 d23

④Creating a mirro r from/opt

#metainit–f d141 1 c1t0d0s4

#metainit d241 1 c1t1t0s4

#metainit d4–m d14

#v i/etc/vfsta b

/dev/dsk/c1t0d0s4/dev/rdsk/c1t0d0s4/opt ufs 1 yes–should be changed to:

/dev/md/dsk/d4/dev/md/rdsk/d4/opt ufs 1 yes–#reboot

#metattach d4 d24

⑤Creating a mirro r from/var

#metainit–f d15 1 1 c1t0d0s5

#metainit d25 1 1 c1t1t0s5

#metainit d5–m d15

#v i/etc/vfsta b

/dev/dsk/c1t0d0s5/dev/rdsk/c1t0d0s5/var ufs 1 yes–should be changed to:

/dev/md/dsk/d5/dev/md/rdsk/d5/var ufs 1 yes–#reboot

#metattach d5 d25

⑥Creating a mirro r from/home

#metainit–f d161 1 c1t0d0s6

#metainit d261 1 c1t1t0s6

#metainit d6–m d16

#v i/etc/vfsta b

/dev/dsk/c1t0d0s6/dev/rdsk/c1t0d0s6/home ufs 1 yes–should be changed to:

/dev/md/dsk/d6/dev/md/rdsk/d6/home ufs 1 yes–

#reboot

#metattach d6 d26

⑦Creating a mirro r from/

#metainit–f d101 1 c1t0d0s0

#metainit d20 1 1 c1t1t0s0

#metainit d0–m d10

#metaroot d0

#loc kfs–fa

#reboot

#metattach d0 d20

#metastat (检查镜像进度)

镜像完成后还需作如下操作

测试ok boot rootdisk系统启动正常。

ok boot mirrordisk系统启动正常。

假如c1t0d0盘坏掉则停机更换硬盘后需做恢复工作如下ok boot mirrordisk-s
