以SUN Fire V880 Server(6*73GB Dsik)为例讲解在Solarsi8下使用命令行的方式安装及维护RAID1和RAID5。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。
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RAID5

系统盘(c1t0d0)分区及镜像盘(c1t1d0)情况:

c1t0d0s0(d10) d0 c1t1d0s0(d20) / 1024M

c1t0d0s1(d11) d1 c1t1d0s1(d21) swap 8192M

c1t0d0s2 c1t1d0s2 overlap 69999M

c1t0d0s3(d13) d3 c1t1d0s3(d23) /usr 4096M

c1t0d0s4(d14) d4 c1t1d0s4(d24) /opt 10240M

c1t0d0s5(d15) d5 c1t1d0s5(d25) /var 2048M

c1t0d0s6(d16) d6 c1t1d0s6(d26) /home free

c1t0d0s7 c1t1d0s7 /metaDB 30M

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/cdrom0/Solaris_8/EA/installer & 选择默认安装就可以。

用root用户登陆,运行以下命令:

#prtvtoc /dev/rdsk/c1t0d0s2|fmthard –s – /dev/rdsk/c1t1d0s2

fmthard: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。

#umount /metaDB

#rm –r /metaDB

#vi /etc/vfstab

将下面这行注释掉或删除,如下:

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

一、RAID1

对各个分区逐一作镜像:

①先生成replicas,这是DiskSuite内部用的。

#metadb –a –f –c 3 c1t0d0s7 c1t1d0s7

#metadb

②Creating a mirror from swap

#metainit –f d11 1 1 c1t0d0s1

#metainit d21 1 1 c1t1t0s1

#metainit d1 –m d11

#vi /etc/vfstab

/dev/dsk/c1t0d0s1 - - swap – no –

should be changed to:

/dev/md/dsk/d1 - - swap – no -

#reboot

#metattach d1 d21

③Creating a mirror from /usr

#metainit –f d13 1 1 c1t0d0s3

#metainit d23 1 1 c1t1t0s3

#metainit d3 –m d13

#vi /etc/vfstab

/dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0s3 /usr ufs 1 yes –

should be changed to:

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

#reboot

#metattach d3 d23
