VXVM如何建立及刪除Disk Group、Volume、FileSystem

如何建立Disk Group、Volume、FileSystem

A、建立Disk Group ： smpdg (假設現在是將c1t1d0 和c1t2d0兩塊物理磁碟來建立smcpdg)
vxdisksetup -i c1t1d0 (格式化物理磁碟)
vxdisksetup -i c2t1d0
vxdg init smpdg smpdg1=c2t1d0 (將物理磁碟加入到Disk Group：smpdg)
vxdg -g smpdg adddisk smpdg2=c1t1d0

然後再來建立Volume、FileSystem
vxassist -g smpdg -U fsgen make lv_smp 17200m layout=nolog smpdg1
vxassist -g smpdg mirror lv_smp layout=nostripe smpdg2
newfs -C -f /dev/vx/rdsk/smpdg/lv_smp

假設現在的一台機器上掛接到/sms
mkdir /sms
chown smp:smp /sms
vxvol -g smpdg startall
mount /dev/vx/dsk/smpdg/lv_smp /sms
umount /sms
vxvol -g smpdg stopall
vxdg deport smpdg

然後再在第二台機器上掛接到/sms
mkdir /sms
chown smp:smp /sms
vxdg import smpdg
vxvol -g smpdg startall
newfs -C -f /dev/vx/rdsk/smpdg/lv_smp
mount /dev/vx/dsk/smpdg/lv_smp /sms
umount /sms

備註：以上是建立一個共享的FileSystem
往往由於smpdg要分配給某一個應用來使用，所以需要再來建立一個個邏輯機運行
時掛接的FileSystem：
vxassist -g smpdg -U fsgen make smpdg-stat 2m layout=nolog smpdg1
vxassist -g smpdg mirror smpdg-stat layout=nostripe smpdg2
newfs /dev/vx/rdsk/smpdg/smpdg-stat

B、建立Disk Group ：smpdbdg
建立Disk Group：
vxdisksetup -i c1t2d0
vxdisksetup -i c2t2d0
vxdg init smpdbdg smpdbdg1=c1t2d0
vxdg -g smpdbdg adddisk smpdbdg2=c2t2d0
vxassist -g smpdbdg -U fsgen make smpdbdg-stat 2m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror smpdbdg-stat layout=nostripe smpdbdg2
newfs /dev/vx/rdsk/smpdbdg/smpdbdg-stat

建立Volume：
vxassist -g smpdbdg -U gen make lv_rootdbs 128m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_rootdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_logdbs 300m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_logdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_phydbs 100m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_phydbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_tempdbs 1000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_tempdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk1 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk1 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk2 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk2 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk3 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk3 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk1 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk1 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk2 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk2 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk3 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk3 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk4 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk4 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk5 1700m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk5 layout=nostripe smpdbdg2

C、賦予Volume屬性
vxedit -g smpdg -v set user=smp group=smp lv_smp
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_rootdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_logdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_phydbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_tempdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk1
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk2
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk3
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk1
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk2
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk3
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk4
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk5

備註：在SUN的機器中在給Volume屬性的時候，等於用chown、chmod來作。

8、如何刪除Disk Volume
其實也就是去激活和Deport的過程，然後再來對物理磁碟重新格式化就完了。
vxvol -g smpdbdg stopall
vxdg deport smpdbdg
vxdisksetup -i c1t0d0
vxdisksetup -i c2t1d0
......

這樣做了之後就不會再有/dev/vx/smpdbdg目錄了。

如何刪除Volume
vxedit -g scpdbdg -fr rm [Volume Name]

9、如何建立共享Disk Volume 
在第一台機器上先建立Disk Volume ，假設已經建設好Disk Volume：smpdg , 現在要在第二台機器上建立共享Disk Volume：smpdg,
則先在的一台機器上將smpdg去激活、並且Deport smpdg：
smcp01>vxvol -g smpdg stopall
smcp01>vxdg deport smpdg

再來在第二台機器上激活、import smpdg:
smcp02>vxdg import smpdg
smcp02>vxvol -g smpdg startall

切換後對用以下三個命令進行查看是否切換成功：
vxdg list //用於查看Disk Group的訊息
vxdisk list //用於查物理磁碟的訊息
vxprint -vt //用於查看所有Volume的訊息

27、sun的Disk Group、Volume的建立總結步驟
SUN：Volumn manager 簡稱VM，在此環境下永久性修改smcpdg/querydg等磁碟捲組的用戶屬性及讀寫權限的時候，不能用chown和chmod來修改的，只能用vxedit來修改。

補充：
初始化物理磁碟：vxdisksetup -i c1t2d0
vxdisksetup -i c2t2d0
建立Disk Volume： vxdg init smpdbdg smpdbdg1=c1t2d0
vxdg -g smpdbdg adddisk smpdbdg2=c2t2d0
建立Disk Volume掛接的FileSystem：
vxassist -g smpdbdg -U fsgen make smpdbdg-stat 2m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror smpdbdg-stat layout=nostripe smpdbdg2
newfs /dev/vx/rdsk/smpdbdg/smpdbdg-stat
建立Volume：
vxassist -g smpdbdg -U gen make lv_rootdbs 128m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_rootdbs layout=nostripe smpdbdg2
修改Disk Volume權限：
vxedit -g smpdg -v set user=smp group=smp lv_smp
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_rootdbs
查看Disk Volume註冊情況：vxdg list
導入Disk Volume：vxdg import smcpdg
註冊Disk Volume：vxvol -g smcpdg start all
反註冊Disk Volume：vxvol -g smcpdg stop all
