MC/SG共享vg中新建fs(无数据迁移)(HP_UX)

l        准备工作:

确定新lv所在的vg       (vg31)

检查目标vg当前的硬盘空间使用情况   (剩余空间足够该操作)

确定新文件系统的信息

lv属性                  -n  lvdt25     -L  20480      -r N

fs属性                  -F vxfs -b 8192 -o largefiles        

mount point名       /oracle/EOP/data25

数据所有者           oraeop:dba

l        前期工作

新建文件系统,mount点,并更改其属性

lvcreate –L 20480 –n lvdt25 vg31

lvchange -r N /dev/vg31/lvdt25     

newfs -F vxfs -b 8192 -o largefiles /dev/vg31/rlvdt25

mkdir /oracle/EOP/data25

chown –R oraeop:dba /oracle/EOP/data25

将新添加的lv信息写入新建的/etc/cmcluster/eofora/eofora.cntl.20070724中

cp /etc/cmcluster/eofora/eofora.cntl /etc/cmcluster/eofora/eofora.cntl.20070724

vi /etc/cmcluster/eofora/eofora.cntl.20070724

将/etc/cmcluster/eofora/eofora.cntl.20070724拷贝到bjeopap2上

rcp /etc/cmcluster/eofora/eofora.cntl.20070724 bjeopap2:/etc/cmcluster/eofora/eofora.cntl.20070724

将vg31生成map文件,并传到bjeopap2上

vgexport -s -p -m /tmp/vg31.map.20070724 /dev/vg31  

rcp /tmp/vg31.map.20070724 bjeopap2:/tmp/vg31.map.20070724

l        待审批批准后再作的步骤:

Bjeopd01上的操作

将文件系统挂载到mount点

mount /dev/vg31/lvdt25 /oracle/EOP/data25

将eofora.cntl文件备份,并将含有新lv信息的eofora.cntl.20070724覆盖至eofora.cntl,使新lv在MC中生效.

cp /etc/cmcluster/eofora/eofora.cntl /etc/cmcluster/eofora/eofora.cntl.20070724.bak

mv /etc/cmcluster/eofora/eofora.cntl.20070724 /etc/cmcluster/eofora/eofora.cntl

bjeopap2上的操作

将vg31去激活

vgexport /dev/vg31

新建vg31

mkdir /dev/vg31

mknod /dev/vg31/group c 64 0x040000 

将bjeopd01传来的map文件import到vg31中

vgimport -s -m /tmp/vg31.map.20070724 /dev/vg31

将现有的eofora.cntl文件备份,并将含有新lv信息的eofora.cntl.20070724文件覆盖到eofora.cntl

cp /etc/cmcluster/eofora/eofora.cntl /etc/cmcluster/eofora/eofora.cntl.20070724.bak

mv /etc/cmcluster/eofora/eofora.cntl.20070724 /etc/cmcluster/eofora/eofora.cntl
