以SUN Fire V880 Server(6*73GB Dsik)為例講解在Solarsi8下使用命令行的方式安裝及維護(hù)RAID1和RAID5。本文檔內(nèi)容都經(jīng)本人實(shí)踐驗(yàn)證過(guò)，但對(duì)于不同機(jī)型僅供參考。
Disk分布情況:

0:c1t0d0

1:c1t1d0

2:c1t2d0

3:c1t3d0

4:c1t4d0

5:c1t5d0

注:0,1做鏡像;2，3，4，5做RAID5

系統(tǒng)盤(pán)(c1t0d0)分區(qū)及鏡像盤(pán)(c1t1d0)情況:

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

系統(tǒng)安裝完成后，使用Solarsi8 software 2 of 2安裝DiskSuite_4.2.1軟件，安裝路徑:/cdrom/cdrom0/Solaris_8/EA/installer & 選擇默認(rèn)安裝就可以。

用root用戶登陸,運(yùn)行以下命令:

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

fmthard:New volume table of contents now in place

上面命令將第二塊硬盤(pán)(c1t1d0)的文件分區(qū)表調(diào)整為和引導(dǎo)盤(pán)一致。

#umount /metaDB

#rm –r /metaDB

#vi /etc/vfstab

將下面這行注釋掉或刪除,如下:

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

一、RAID1

對(duì)各個(gè)分區(qū)逐一作鏡像:

①先生成replicas,這是DiskSuite內(nèi)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

④Creating a mirror from /opt

#metainit –f d14 1 1 c1t0d0s4

#metainit d24 1 1 c1t1t0s4

#metainit d4 –m d14

#vi /etc/vfstab

/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 mirror from /var

#metainit –f d15 1 1 c1t0d0s5
#metainit d25 1 1 c1t1t0s5
#metainit d5 –m d15
#vi /etc/vfstab
/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 mirror from /home

#metainit –f d16 1 1 c1t0d0s6

#metainit d26 1 1 c1t1t0s6

#metainit d6 –m d16

#vi /etc/vfstab

/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 mirror from /

#metainit –f d10 1 1 c1t0d0s0

#metainit d20 1 1 c1t1t0s0

#metainit d0 –m d10

#metaroot d0

#lockfs –fa

#reboot

#metattach d0 d20

#metastat (檢查鏡像進(jìn)度)

鏡像完成后，還需作如下操作:

修改EEPROM

ok devalias(察看啟動(dòng)設(shè)備)

ok nvalias rootdisk /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@0,0

ok nvalias mirrdisk /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@1,0

ok setenv boot-device rootdisk mirrdisk

eeprom命令:

boot-device=rootdisk mirrdisk

use-nvramrc?=true

nvramrc=devalias mirrdisk /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@1,0

devalias rootdisk /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@0,0

#ls -l c1t0d0s0

lrwxrwxrwx 1 root root 70 1月 2 10:45 c1t0d0s0 -> ../../devices/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000000870e80e7,0:a

對(duì)應(yīng):/pci@8,600000/SUNW,qlc@4/fp@0,0/disk@0,0

root@voiplnjvr4 # ls -l c1t1d0s0

lrwxrwxrwx 1 root root 70 1月 2 10:45 c1t1d0s0 -> ../../devices/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000000870fb287,0:a

對(duì)應(yīng):/pci@8,600000/SUNW,qlc@4/fp@0,0/disk@1,0

測(cè)試:

ok boot rootdisk 系統(tǒng)啟動(dòng)正常。

ok boot mirrordisk 系統(tǒng)啟動(dòng)正常。

假如c1t0d0盤(pán)壞掉，則停機(jī)更換硬盤(pán)后需做恢復(fù)工作，如下;

ok boot mirrordisk -s

#metadb -d c1t0d0s7

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

#metadb –a –f –c 3 c1t0d0s7

#halt

ok boot mirrordisk

#metareplace -e d0 c1t0d0s0

d0: device c1t0d0s0 is enabled

#metareplace -e d1 c1t0d0s1

d1: device c1t0d0s1 is enabled

#metareplace -e d3 c1t0d0s3

d3: device c1t0d0s3 is enabled

#metareplace -e d4 c1t0d0s4

d4: device c1t0d0s4 is enabled

#metareplace -e d5 c1t0d0s5

d5: device c1t0d0s5 is enabled

#metareplace -e d6 c1t0d0s6

d6: device c1t0d0s6 is enabled

#metastat (檢查鏡像恢復(fù)進(jìn)度)

二、RAID5

#metainit d55 –r c1t2d0s2 c1t3d0s2 c1t4d0s2 c1t5d0s2

#metastat d55 (檢查RAID5的進(jìn)度)

作完后reboot

#newfs /dev/md/rdsk/d55

#mkdir /raid5

#vi /etc/vfstab

添加一行:

/dev/md/dsk/d55 /dev/md/rdsk/d55 /raid5 ufs 2 yes –

#reboot

RAID5壞掉一個(gè)盤(pán)的恢復(fù)方法:

例c1t4d0盤(pán)壞掉，更換壞硬盤(pán)后作如下工作:

ok boot -r

#metareplace –e d55 c1t4d0s2

#metastat d55

卸去RAID5的方法:

#umount /raid5

#metaclear d55

#vi /etc/vfstab

注釋此行:

#/dev/md/dsk/d55 /dev/md/rdsk/d55 /raid5 ufs 2 yes –
